"Ultra Wideband Dual Circularly Polarized Patch Antenna for 5G and Cube" by Mohamed El Hammoumi, Najiba El Amrani El Idrissi et al.
In this paper, we propose a compact single-fed corner arc-truncated square patch antenna with T -diagonal slot and periodically defected ground (PDGS) plane for X band and mm-wave CubeSat applications. A square patch antenna printed on a grounded FR4 slab is used as the building block. Furthermore, its performance is enhanced in terms of impedance bandwidth by adding periodically circular slots in the ground plane to obtain ultra-wideband characteristics. Dual circular polarization, at two reson...
