Broadband, Low Profile, Circularly Polarized, Slot Antenna With S‐Shaped Coupling Structure for Vehicle‐to‐Satellite Communications
In this study, a low‐profile circularly polarized (CP) slot antenna featuring an S‐shaped coupling structure is proposed for vehicle‐to‐satellite communications. By leveraging the S‐shaped coupling feed, both wide impedance bandwidth and CP radiation are achieved. In addition, a defected ground structure (DGS) is incor...
