Design of a Wideband Microstrip Antenna for Mobile Handset Applications

Abstract: This article summarizes the design, construction and experimental results for a new wideband miniaturized antenna operating in the 1.9 GHz band. This antenna is intended for handset applications, and may also be used as an element in a larger array. Using shorting pins at the zero-potential plane, a compact antenna with a 21 percent bandwidth was designed and tested, with quite good agreement between measured data and the performance predicted by simulation.

Shorted microstrip patch antenna with parasitic element

Abstract: This paper describes a small microstrip antenna that operates at 2.45 GHz which is the frequency band for wireless applications such as WiFi and Bluetooth. Two techniques of enhancing the performance of the conventional patch antenna, which are shorting pins and parasitic element, were studied. The results are obtained through simulation and measurement. Additional slots were included to further enhance the bandwidth of the antenna. Comparisons among conventional patch antenna, shorted patch antenna and shorted patch with parasitic element were conducted in terms of return loss and radiation pattern. From the measurement results, the bandwidth of the modified antenna increased up to 2% compared to the conventional patch antenna. By shorting the patch also reduces its width from 30 mm to 15 mm or 50% reduction. The improvement of gain could be achieved by adding a layer of parasitic element. All simulation was done using CST Microwave Studio 2008.

Shorted patch antenna with parasitic elements

Abstract: This paper focuses on two techniques to improve the performance of a conventional rectangular microstrip patch antenna in terms of impedance bandwidth and gain. The effect of shorting the patch and adding layers of parasitic elements will be investigated in this paper using CST Design Studio. The antenna was designed to tune at 2.45 GHz and uses FR4 board. It is found that notable increase of bandwidth and gain after modifications were made to the normal patch.

Design Of Compact E-Shape Microstrip Patch Antenna For 4G Communication Systems

Abstract: In this paper, the design and analysis of E-shape microstrip patch antenna for the 4G mobile communication system is presented. The shape of proposed antenna will provide the wide bandwidth which is required for the operation of 4G mobile communication systems. The operating frequency of antenna is 3GHz, The antenna design consists of a single layer of thickness 1.6 mm with dielectric constant of 4.2 and fabricated on glass epoxy material. The simulation results of proposed E-Shape antenna are done by the help of IE3D Zeland Software (Version 12.0). For the analysis of antenna we used the Cavity Model. This antenna is fed by a co-axial probe feeding. The effects of different antenna parameters like return loss, voltage standing wave ratio (VSWR) are also studied. Keywords— Microstrip patch antenna, Return loss, VSWR.
