A novel circularly polarized hexagonal ring microstrip patch antenna with asymmetrical feed is proposed for S, C, and X‐band applications. A semi‐arc‐shaped slot is integrated into the ground plane, and the hexagonal ring is tilted by an angle of 25° with respect to the microstrip‐line feed (asymmetric), which creates a circularly polarized UWB. The simulation of the proposed antenna is carried out using Ansoft HFSS v.13 and the measurement is done with an N5230A vector network analyzer. The simulated and the measured results of our proposed antenna are in good agreement. The successful implementation of the asymmetrical feed shows a broader impedance bandwidth of 134% (B.W = 9.55 GHz) from 2.34 to 11.89 GHz at 7.12 GHz of the center frequency. The 3‐dB axial ratio B.W is 2.8% (7.1‐7.3 GHz) and 21.8% (9.8‐12.2 GHz) in the UWB range. The average gain of the proposed antenna is 4.15 dBi. Good RHCP waves are also found in the x‐z and y‐z planes. The proposed antenna can be effectively used in S, C, and X‐band applications.

“…Besides having a wide 3 dB ARBW sometimes, it is desirable to have an antenna with multiple circularly polarized (CP) bands for interference reduction between various frequency bands. Keeping this in mind, a variety of antenna designs having multiple CP bands were proposed in the available literature …”

“…Various novel techniques for getting multiple CP bands were proposed in Refs . In Ref , solid arcs and grounded tuning stub were used for achieving dual circularly polarized bands having 3 dB ARBW of 15.1% (2.15–2.6 GHz) and 4.1% (5.67–5.91 GHz), respectively.…”

“…Fractal geometry was used on patch for getting triple circularly polarized bands having 3 dB ARBW of 3.2%, 1.6%, and 3% at operating frequencies 2.45, 3.4, and 5.8 GHz in Ref . In Ref , vacant quarter printed rings at 90° phase difference were used on patch for getting triple bands having 3 dB ARBW of 9.7% (2.34–2.58 GHz), 4.5% (5.14–5.38 GHz), and 2.7% (5.72–5.88 GHz) respectively. Moreover, these antennas have a complex structure and large size, thus it is difficult to integrate them in portable handheld terminals.…”

This article presents two compact circularly polarized microstrip antennas with a very wide 3 dB axial ratio bandwidth and triple circularly polarized bands. A hexagonal stub (circular polarization element) along with tuning element in the ground plane is used for achieving wide 3 dB ARBW in antenna-1, while a novel approach of using a parasitic strip around the circular polarization element is used in antenna-2 for introducing band elimination notches in the circularly polarized band of antenna-1. The antenna-1 has a 210 dB impedance bandwidth of 12.34% (3.8-4.3 GHz), 84.02% (4.9-12 GHz), and 3 dB ARBW of 79.94% (4.9-10.9 GHz). The antenna-2 displays circularly polarized band elimination notch characteristics with 210 dB impedance bandwidth of 24

“…While Designing of symmetrical microstrip antenna, it has been found that microstrip antenna has narrow Bandwidth [9], Asymmetrical position of patch antenna on ground affect the performance of antenna that is to enhance bandwidth it was also found that asymmetrical position of slot on patch affects performance of antenna [10] that is asymmetrical L-shape, U-shape position of slot on patch affects the performance. In another study [10,11] reported asymmetrical L-shaped slot on patch antenna for UWB application with acceptable return loss that is10dB and peak gain of 2.2 to 6.1 dBi for operating bandwidth 3.01-11.30 GHz frequencies.…”
