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.

Abstract A single-layer ultra-wideband (UWB) stop-band frequency selective surface (FSS) has several advantages in wireless systems, including a simple design, low debugging complexity, and an appropriate thickness. This study proposes a miniaturized UWB stop-band FSS design. The proposed FSS structure consists of a square-loop and metalized vias that are arranged on a single layer substrate; it has an excellent angle and polarization-independent characteristics. At an incident angle of 60°, the polarization response frequencies of the transverse electric and magnetic modes only shifted by 0.003 f0 and 0.007 f0, respectively. The equivalent circuit models of the square-loop and metallized vias structure are analysed and the accuracy of the calculation is evaluated by comparing the electromagnetic simulation. The 20 × 20 array constitutes an FSS reflector with a unit size of 4.2 mm × 4.2 mm (less than one-twentieth of the wavelength of 3 GHz), which realizes an UWB quasi-constant gain enhancement (in-band flatness is <0.5 dB). Finally, the simulation results were verified through sample processing and measurement; consistent results were obtained. The FSS miniaturization design method proposed in this study could be applied to the design of passband FSS (complementary structure), antennas and filters, among other applications.
