“…One of the important applications of this antenna is the use of transmitting or receiving systems that require circular polarization. Circular polarization is obtained by perturbing an unsymmetrical structure which results in orthogonal field components with quadrature phase-shift [1][2][3]. Circularly polarized antennas are more useful in wireless communications, RFID (radio-frequency identification), wireless LAN, and GPS.…”

This paper presents a circularly polarized microstrip patch antenna for WiMAX (Worldwide Interoperability for Microwave Access) application with improved impedance bandwidth and axial ratio compared to the existing designs. The antenna is designed at a resonant frequency of 3.56GHz on the FR4 substrate with 2mm thickness. The dimensions of the antenna are 0.35λo×0.35 λo×0.023λo and it is fed through a probe feed. An impedance bandwidth of 360MHz (10.11%) in the frequency range of 3.44GHz−3.8GHz, with a gain of 3.16dBi, axial ratio bandwidth of 1.9% (3.56GHz−3.63GHz) and VSWR<2 are obtained.

“…There is circular polarization (CP) due to the orthogonal field components of electric fields [6]. Various techniques are used to enhance the bandwidth of CP antennas such as folding the edge of the radiating patch antenna with slots loaded; with these techniques, the size of the antenna reduces to 44.8 %, so that the antenna appropriatness for the 5G mobile phone is discussed in [7].…”

The research paper presents a novel and compact circularly polarized (CP) antenna for a 5G wireless local area network (WLAN) application. It consists of a circular patch and a coaxial probe feed radiator. Circular polarization (CP) is attained by symmetric semi-circular slits of radius r1 at three edges of a circular path with 90° in direction, and the other semicircular slit is of different radius r2. To improve the impedance bandwidth and axial ratio, the radius of the fourth semicircular slit on circular patch antenna is varied. The design is verified by fabricating a compact antenna of 0.65λ0 × 0.65λ0 × 0.01λ0. The measured 10 dB impedance bandwidth is 3.9 % (5.36–5.56 GHz), 3-dB axial ratio bandwidth is 1.1 % (5.43–5.49 GHz) and gain of 6.6 dBi at resonant frequency of 5.37 GHz is obtained. The authors also describe two-dimensional radiation patterns of azimuth and elevation plane surface current distribution of the CP patch, VSWR < 2. The proposed CP antenna is suitable for the 5G WLAN application. The proposed design is compared with various techniques in literature and tabulated. The measured results are also discussed and they are in good agreement with simulated results.
