“…8,9 Although, the techniques are sufficiently developed for obtaining the wideband response with single feeding, still, the researchers are struggling for obtaining the high gain in the case of wideband CPDRAs. 10,11 Few techniques have been utilized for improving the gain of wideband CPDRA like staking of deformed DR geometries 10 and using frequency selective surfaces (FSS). 12 The use of staking generally increases the height of the DR and placing FSS is a complex task.…”

“…14 This antenna provides the inconsistent gain profile throughout the passband in the passband, which is the most required thing in the case of CPDRA arrays. 10 The other method those were utilized are related to the use of superstrates like reported in References 12,16,17. The use of superstrates is a quite complex task due the increased antenna height.…”

“…CP-DRA has potential to surmount all the downsides of LP-DRA. It also overpowers the effect on the orientation of transmitting and receiving antennas [1][2][3]. Most of the circularly polarized antenna have dual-feeding mechanism which increases the size and complexity of the circuit.…”

“…It gives a percentage CP bandwidth of 24.75%. 15 Varshney et al presented inverted-Sigmoid-shaped DRA for multiband CP applications. However, the antenna design provides better results, but it suffers from a complex fabrication process.…”
