Minaret Shape Micro-Strip Patch Antenna with Partial Ground Plane for Lower 5G and Wi-Max Applications

Antennas are a difficult component to design, yet they play critical functions in wireless transmission systems. To construct the required antenna, the antenna designer must overcome enormous challenges in getting all of the antenna's optimal qualities. Antenna designers must consider antenna factors like bandwidth, return loss, VSWR, gain, directivity, efficiency, and so on, for specific applications. So keep all parameter values as optimal as possible; sometimes you may need to adjust the design of the antenna from its standard shape. The present investigation describes the development of a partial ground-plane micro-strip patch antenna in the shape of a minaret for use in lower 5G and Wi-MAX networks. A microstrip patch antenna with a minaret-shaped radiating element and a partial ground plane is suggested.

In this study, an antenna is proposed that operates at THz spectrum for sixth generation (6G) short-range future wireless communications. A modified photonic band gap (MPBG) substrate is employed to design an octagonal ring shaped microstrip patch antenna with wideband and high gain properties. Unlike the conventional photonic band gap (PBG) form, the proposed MPBG substrate structure is created by variable sized cylindrical air holes. The radii of each air cylinder in the row is determined with the help of particle swarm optimization (PSO) algorithm, where the goal is set to achieve the highest gain and impedance bandwidth (S_11≤-10 dB) possible. The simulation results of the antennas that are built on 1) non-PBG, 2) conventional PBG and 3) the proposed MPBG substrate structures are compared. It is observed that the radiation performance is most enhanced by implementing MPBG structure. In comparison to the antenna without PBG, the reported MPBG structure offers almost 300% gain and 11% bandwidth improvement. To summarize, the designed antenna with its proposed MPBG substrate structure achieves an excellent radiation performance within a wide operating bandwidth.

Field Asymmetry Ratio: A new quantitative parameter to select microstrip antenna geometries for low cross-polarization application

This paper proposes a new quantitative parameter on identifying the primary factor for appropriate geometry selection of microstrip patch antennas dedicated to low cross-polarization (XP) applications. The significance of point-symmetric (PS) and non-point-symmetric (NPS) geometries has been analyzed on the basis of ‘Field Asymmetry Ratio’ (FAR), a new parameter, defined to quantify the level of electric field asymmetry leading to XP radiation in any regular shaped microstrip patch antennas. Based on this analysis, a conclusive inference has been established on the importance of point-symmetric patch geometry selections to achieve lower XP radiation. The 6-element circular cluster of shorting pins (CCSP) has been adopted as the XP suppression tool for S-band applications to validate the proposition. An XP suppression of approximately 9 dB at the boresight and 5 dB at ±30°around the boresight in H-plane has been achieved for the square-shaped patch geometry.
