TL;DR: A microstrip array antenna consist of a 4×4 rectangular-shaped patch radiating element with a microstrip line feeding technique using a quarter-wavelength transformer impedance matching that is suitable and promising for C-band satellite applications is proposed.
Abstract: C-band satellite receiving antenna requires a high gain to reach the long-distance wireless transmission between ground station and satellite. Among various antenna types, the advantages of microstrip antennas are low profile, easy to fabricate, easy to feed, easy to incorporate with other microstrip circuit elements and integrate into systems, and easy to use in an array to increase the directivity. This paper proposes a microstrip array antenna consist of a 4×4 rectangular-shaped patch radiating element with a microstrip line feeding technique using a quarter-wavelength transformer impedance matching. The array antenna technique has the purpose of obtaining high gain and achieving greater directivities. This research considers an FR-4 Epoxy substrate in which the thickness and dielectric constant are 1.6 mm and 4.3, respectively, to deploy the antenna structure. The antenna design is simulated and parameterized by using CST Microwave Studio to obtain the most optimum performance. The result shows that the 4×4 microstrip rectangular patch array antenna has an overall gain of 13.7 dB, and from the return-loss graph shows, the working bandwidth is 734 MHz ranges from 3.794–4.528 GHz. These results indicate that the proposed antenna design is suitable and promising for C-band satellite applications.

TL;DR: In this paper, a circular ring microstrip patch antenna using aperture coupling feeding techniques with rectangular slots on the patch for LTE was designed, which produced multi resonant frequencies than the original characteristics.
Abstract: This paper designed circular ring microstrip patch antenna using aperture coupling feeding techniques with rectangular slots on the patch for LTE. The use of aperture coupling feeding techniques were expected to optimize antenna parameters performance. The addition of rectangular slots on the patch produced multi resonant frequencies than the original characteristics. The simulated optimized design generated 1.8 GHz, 2.1 GHz, and 2.72 GHz with Return Loss value -22.3683 dB, -18.8133 dB, -24.3451 dB and VSWR value 1.1648, 1.259, 1.1291. Meanwhile, the measurement results of fabricated antenna showed the frequency produced by the antenna was 1.8 GHz with value of Return Loss and VSWR -18.257 dB and 1.278 in a reference value of VSWR < 2 and Return Loss < -10 dB.

TL;DR: In this article , the authors analyzed the bandwidth performance of microstrip patch antenna (MPA) using novel proximity coupled fed and comparing with aperture coupled fed on 50 Ω characteristics impedance at 10 GHz.
Abstract: Aim: To analyze the bandwidth performance of microstrip patch antenna (MPA) using novel proximity coupled fed and comparing with aperture coupled fed on 50 Ω characteristics impedance at 10 GHz. Material and Methods: The RF characteristics (Gain, Bandwidth, Return loss, Voltage standing wave ratio (VSWR), and Impedance) of proximity coupled fed (n = 19) with aperture coupled fed (n=19) on 50 Ω characteristic impedance at the frequency range of 10 GHz. The 19 samples were calculated by sample calculation with pre-test power 0.8. Result: Proximity coupled fed has significantly higher bandwidth performance (Bandwidth: 523 MHz) than aperture coupled fed (Bandwidth: 462 MHz). The optimized dimensions for proximity coupled fed were 50 x 50 x 1.6 mm3 and aperture coupled fed was 47.64 x 39.04 x 1.6 mm3. Conclusion: The proximity coupled fed antenna is reported to have significantly better bandwidth performance than aperture coupled fed antenna.

TL;DR: In this article, a rectangular microstrip patch antenna with enhanced performance for radar and satellite communication is presented, which exhibits resonant frequency at 7.5 GHz with return loss of −63.83 dB.
Abstract: We demonstrate a rectangular microstrip patch antenna with enhanced performance for radar and satellite communication. The FR-4 epoxy substrate-based antenna exhibits resonant frequency at 7.5 GHz with return loss of −63.83 dB. The implementation of defected ground structure yields wideband response with substantial increase in the percentage bandwidth from 6.13 to 39.17%. The designed antenna’s structure has significantly high gain and high directivity of 8.5 dB and 8.21 dBi, respectively. The rectangular patch, feedline, and ground components are of copper. The performance evaluation is done in terms of return loss, resonant frequency, gain and directivity. A comprehensive analysis on parametric alterations is carried out to obtain the optimized structure. The parametric analysis will be discussed thoroughly illustrating the effect on antenna performance. The structure is fabricated and tested using anechoic chamber integrated E5071C Network Analyzer. We found that the practical results match very closely with simulated results.

TL;DR: Directional radiation pattern obtained is useful for application such as mobile full duplex relaying which utilises directivity to isolate the self interference.
Abstract: This paper presents a design of compact wideband directional antenna with L-slot technique on the ground plane for LTE application at frequency of 2.6GHz. The structure of the design consist of three layers of conductive copper and separate by two layers of FR4 substrate with the permittivity of 4.7. Two L-slots has been added to the ground plane for bandwidth enhancement. The simulation has been performed and meets the requirement of LTE standard with the centre frequency of 2.6GHz and achieves the bandwidth 247MHz at 10dB return loss, a peak gain of 4.114dB in simulation. Directional radiation pattern obtained is useful for application such as mobile full duplex relaying which utilises directivity to isolate the self interference.

TL;DR: In this article, the authors proposed two novel designs of a multiband antenna using multiple rings, one consisting of a set of self-similar circular rings and the other by varying the shape of the circular structure to an elliptical one.
Abstract: This paper proposes two novel designs of a multiband antenna using multiple rings. The first design consists of a set of self-similar circular rings. This is an alternative to the recently reported triangular fractal Sierpinski gasket monopole antenna, and comparison is made to this and the circular disk monopole antenna. The second design is realized by varying the shape of the circular structure to an elliptical one. Larger bandwidth and improved patterns are achieved. In comparison to the circular disk, improved radiation pattern control at higher operating bands, due to the discrete structure of the multiple rings, is shown by numerical and experimental results. The bandwidth is significantly larger than the Fractal Sierpinski gasket and Parany monopole.

Abstract: A method for calculating the resonant frequency of electrically thin and thick rectangular microstrip antennas, based on the backpropagation multilayered-perceptron network, is presented. The method can be used for a wide range of substrate thicknesses and permittivities, and is useful for the computer-aided design (CAD) of microstrip antennas. The calculated resonant-frequency results are in very good agreement with the experimental results reported elsewhere.

TL;DR: In this article, the design of higher order dominant mode circular microstrip antennas is addressed, with an example and measurements for the n=3 case, and a design example is given for a roof-mounted circular patch for vehicular communications.
Abstract: For circular microstrip antennas, single-mode design techniques work well for the dominant mode (n=1, where n is the azimuthal dependence of the fields in the antenna), but this is not the case for zero-order (n=0) and higher order (n>1) modes, where a modal expansion is necessary. The design of higher order dominant mode circular microstrip antennas is addressed, with an example and measurements for the n=3 case. Measurements for the n=3 modes show reasonable agreement with theory in the forms of the impedance loci, but the frequency dependence is in error by the order of the bandwidth of the antenna. A design example is given for a roof-mounted circular patch for vehicular communications. The example indicates that an n=3 dominant mode patch can be used as a two-port antenna for diversity applications or with a 90 degrees phase shifter and adder as a single-port antenna for omnidirectional coverage with (essentially) circular polarization. >
