TL;DR: In this paper, a low-cost and high-gain microstrip/dielectric resonator hybrid antenna was proposed for short-range millimeter-wave communication systems operating in the 57-65 GHz frequency band.
Abstract: A new low-cost and high-gain microstrip/dielectric resonator hybrid antenna is described for short-range millimeter-wave communication systems operating in the 57-65 GHz frequency band. The impedance bandwidth (VSWR < 2) of the proposed antenna is wide enough to entirely cover this portion of unlicensed spectrum (ap 5%). Furthermore, the measured high gain (11.9 plusmn 0.9 dB) is fairly constant across the operating band. A study of the electric and magnetic fields inside the hybrid structure concludes that the excitation of a higher-order mode inside the dielectric resonator (namely the HEM15delta hybrid mode) is responsible for the improved gain since the electrical size of the antenna is increased. In order to validate the proposed design, theoretical calculations and measurements from a fabricated prototype are provided.

TL;DR: In this paper, a single-element circularly polarized antenna for millimeter-wave applications is presented, which uses a simple hybrid microstrip/elliptical dielectric ring resonator configuration to achieve a relatively high antenna gain.
Abstract: A new single-element circularly polarized antenna for millimeter-wave applications is presented in this letter. A simple hybrid microstrip/elliptical dielectric ring resonator configuration is used to achieve a relatively high antenna gain. A reversed T-shaped coupling slot generates the circular polarization. The ring-shaped dielectric resonator is used to increase the gain and fine-tune the axial ratio (AR) bandwidth. Measurements show that an impedance bandwidth of 12% and a considerably wide axial ratio bandwidth (10%) are possible. The measured gain is maintained over 9 dB for a large portion of the operational bandwidth.

TL;DR: In this paper, a dual-fed dual-polarized antenna for millimeter-wave applications is proposed, which achieves a very large impedance bandwidth (11.33 GHz) and high gain (peak value of 12.9 dB) with a simple low-cost hybrid configuration.
Abstract: This paper introduces a novel dual-fed dual-polarized antenna for millimeter-wave applications. Both a very large impedance bandwidth (11.33 GHz) and a high gain (peak value of 12.9 dB) are achieved with a simple low-cost hybrid configuration. The isolation between the two independent feed ports is better than 19 dB across most of the operating bandwidth.

TL;DR: In this paper, a high-gain circularly polarized antenna for operation at 60 GHz was presented, which generates more than 11 dB of gain over a 3 % axial ratio bandwidth.
Abstract: A high-gain circularly polarized antenna for operation at 60 GHz has been presented. It generates more than 11 dB of gain over a 3 % axial ratio bandwidth. All dimensions were chosen to allow fabrication with a simple PCB-based process, making the proposed antenna a viable candidate for low-cost millimeter-wave communication systems.

TL;DR: The basic characteristics of dielectric resonator antennas are explained, with emphasis on the effect of the form factor on their resonance (operating) frequencies.
Abstract: This paper explains the basic characteristics of dielectric resonator antennas (DRAs), with emphasis on the effect of the form factor on their resonance (operating) frequencies. It is followed by discussions on their recent developments in higher order mode, circularly polarized, dual function, and transparent designs over the last few years. The idea of using glass DRAs as decoration antennas is proposed and demonstrated for the first time.

TL;DR: In this paper, a single-fed low-cost wideband and high-gain slotted cavity antenna based on substrate integrated waveguide (SIW) technology using high-order cavity modes is demonstrated.
Abstract: A novel single-fed low-cost wideband and high-gain slotted cavity antenna based on substrate integrated waveguide (SIW) technology using high-order cavity modes is demonstrated in this paper. High-order resonant modes ( ${\text T}{{\text E}_{{130}}}$ , ${\text T}{{\text E}_{{310}}}$ , ${\text T}{{\text E}_{{330}}}$ ) inside the cavity are simply excited by a coaxial probe which is located at the center of the antenna. Energy is coupled out of the cavity by a $3 \times 3$ slot array etched on the top surface of the cavity. Two antennas with different polarizations are designed and tested. Measured results show that the linearly polarized prototype achieves an impedance bandwidth $\left(\vert{{\text S}_{{\text 11}}}\vert of $> {26}\% $ (28 to 36.6 GHz), and a 1-dB gain bandwidth of 14.1% (30.3 to 34.9 GHz). In addition, a measured maximum gain of 13.8 dBi and radiation efficiency of 92% are obtained. To generate circularly polarized radiation, a rotated dipole array is placed in front of the proposed linearly polarized antenna. Measured results show that the circularly polarized antenna exhibits a common bandwidth (10-dB return loss bandwidth, 3-dB axial ratio bandwidth, and 1-dB gain bandwidth) of 11%.

TL;DR: In this paper, a new millimeter-wave (MMW), electromagnetic band-gap (EBG) structure without the use of metallic vias or vertical components is formed by etching two slots and adding two connecting bridges to a conventional uniplanar EBG unit-cell.
Abstract: A new millimeter-wave (MMW), electromagnetic band-gap (EBG) structure is presented. The proposed EBG structure without the use of metallic vias or vertical components is formed by etching two slots and adding two connecting bridges to a conventional uniplanar EBG unit-cell. The transmission characteristics of the proposed EBG structure are measured. Results show that the proposed EBG structure has a wide bandgap around the 60 GHz band. The size of the proposed EBG unit-cell is 78% less than a conventional uniplanar EBG, and 72% less than a uniplanar-compact EBG (UC-EBG) operating at the same frequency band. Moreover, and despite the fabrication limitations at the 60 GHz band, the proposed EBG unit-cell provides at least 12% more size reduction than any other planar EBG structures at microwave frequencies. Its enhanced performance and applicability to reduce mutual coupling in antenna arrays are then investigated. Results show a drastic decrease in the mutual coupling level. This EBG structure can find its applications in MMW wireless communication systems.

TL;DR: In this article, a stair-shaped dielectric resonator antenna (DRA) with a wideband circular polarization (CP) radiation is introduced for wireless local area network (WLAN) applications.
Abstract: A circularly polarized stair-shaped dielectric resonator antenna (DRA) with a wideband circular polarization (CP) radiation is introduced for wireless local area network (WLAN) applications. This antenna is implemented by using two rectangular dielectric resonators (DRs), which are joined together to form a stair-shaped dielectric resonator antenna (DRA). In this structure, the excitation of multiple orthogonal modes leads to a wideband CP bandwidth. Measured results show that the proposed antenna has an axial ratio (AR) bandwidth of 22% (5.2–6.5 GHz), an impedance bandwidth of 37% (4.6–6.7 GHz), and a peak gain of 5.7 dB. In addition, the antenna radiation efficiency of more than 90% is achieved.
