Circularly Polarized Sector- shaped Patch Antenna for WLAN Applications

A Compact Circularly Polarized Rotated L-Shaped Antenna With J-Shaped Defected Ground Strucutre for Wlan and V2x Applications

“…The CP radiation and high radiating performance antennas with their favorable features such as low profile, light weight, and planner structure are very essential for modern wireless communication including Industrial Internet of Things (IIoT), machine to machine communication in aerospace, security, commercial, agricultural as well as V2X applications [1,2]. In this context, several antenna designers and researchers have reported outstanding CP/dual CP antennas to meet the growing demand for broad bandwidth and multimedia applications in the near future [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Among them, slots with various geometries of the radiating element are gaining more attention [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] as they can be utilized to generate CP radiations easily for desired wireless bands.…”

“…To reduce the cost, the antennas in [8][9][10][11] are designed on cost-effective and easily available FR-4 substrate. Here, a fan-shaped CP antenna operating in the 2.4 GHz WLAN band is reported in [8], while [9] has reported a fractal defected ground patch antenna operating in the 1.55 GHz band.…”

“…In [10], a truncated square aperture patch antenna operating in the 2.4/5 GHz WLAN band has been investigated, whereas a gap coupled patch antenna operating in the 3.6/5.3 WLAN/WiMAX band is discussed in [11]. However, the antennas in [8][9][10][11] have demonstrated a very narrow ZBW and do not cover the entire band of operation. Wideband antennas designed on cost-effective FR-4 substrate have been reported in [12][13][14][15][16].…”
