Rectangular Microstrip Patch Antenna

A rectangular microstrip patch antenna over ultra-wideband with superstrate are designed and analyzed. Four iterations A, B, C, D were designs. Iterations A and B represent the parametric study of the microstrip patch antenna. Iteration C represents Ultrawide band microstrip patch antenna with peak realized gain 4.196 dB at frequency 10.12 GHz, the gain was enhance using superstrate above the microstrip patch antenna as in iteration D, a novel enhancement happens for the whole ultra-wideband frequency band (3.1–10.6 GHz) with highest salient realised gain of 5.3 dB at frequency 10.55 GHz. The proposed antenna gain at iteration D is increased by 26.49%, which is useful for many applications such as satellite communication. Simulation and discussion results of the proposed antenna are present within this paper.

Microstrip Patch

A microstrip patch antenna is designed for a wearable antenna. The performance of microstrip patch antenna loaded with reactive impedance surface (RIS) is described in terms of gain, bandwidth and return loss. The antenna is investigated in two conditions which are conventional microstrip antenna with RIS and without RIS. The designed antenna is also aimed at size reduction therefore it will be suitable for a wearable application. This antenna which is made fully using textile and it is designed for operation in the 2.45 GHz band. The performance of microstrip patch antenna loaded with RIS is described in terms of gain, bandwidth, return loss and radiation pattern. The antenna designed with RIS operates at 2.45 GHz. Bandwidth enhancement is achieved with RIS where the designed antenna can cater frequency from 2.4 GHz to 3 GHz. A gain enhancement is achieved of 20% is achieved compared with the conventional patch antenna. Although the size of the patch is reduced with the introduction of RIS, the overall size of the antenna with the substrate is almost similar to the conventional patch antenna. However, the performance of the antenna is greatly enhanced with the use of RIS.
