“…Recently, a truncated square patch suspended over the ground plane with capacitive feed for obtaining circular polarization and wideband to cover the entire frequency of GPS (1.15-1.6 GHz) was discussed in [9]. The simulation results showed better axial ratio BW of 16% and impedance BW of 32% in [9]. The axial ratio BW is substantially more than earlier reported results in [5,6].…”

Wideband Circularly polarized antenna receive much attention in the wireless communication applications such as Global positioning system (GPS) and Personal communication system (PCS). In this paper, a microstrip square patch, truncated in opposite corners, suspended above the ground plane is proposed. The geometry incorporates the capacitive feed strip which is fed by a coaxial probe. The proposed structure is designed, simulated and fabricated to cover the entire frequency of GPS, i.e., L 1 (1.575 GHz), L 2 (1.227 GHz), and L 5 (1.176 GHz), covering from (1.15 GHz-1.6 GHz). The parameters such as return loss, VSWR, impedance, radiation efficiency axial ratio and radiation pattern are used for analyzing the performance of the antenna. Both simulated and experimental results are presented and they exhibit broadband characteristics, covering the desired frequency bands.

“…The single layered antenna had been designed to resonate in dual frequency mode and achieved reduction in patch size up to 71%.The design was obtained by cutting rectangular slots at two sides of the patch. A wideband circularly polarized microstrip patch antenna [3] was proposed. In this, square patch was truncated in opposite corners.…”

A compact dual band microstrip patch antenna is designed for C (4-8 GHz) band and X (8-12 GHz) band applications. The proposed antenna consists of a rectangular patch having four U-slots and one I-slot with H-shaped DGS (Defected Ground Structure) . The antenna has overall size of 25mm by 23 mm and gives bandwidth of about 140 MHz from 5.85 GHz to 6 GHz and of about 1.21 GHz from 7.87 to 9 GHz at resonating frequency of 5.9 GHz and 8.8 GHz respectively with DGS. The antenna without DGS mainly resonates at 6 GHz and 8.7 GHz. The antenna with DGS has return losses -16.29dB at 5.9 GHz and -18.28 dB at 8.8 GHz, gain 1.2 dBi for 5.9 GHz and 4.4 dBi for 8.8 GHz. This antenna has been analyzed using IE3D electromagnetic solver.
