Abstract

A 2×2 phased array consisting of beam reconfigurable four-arm Right Handed Circularly Polarized (RHCP) curl unit element antennas is presented. This array is designed at test frequency of 5.2 GHz and can undertake a high-gain near-the-horizon scanning with low grating lobes. Each curl antenna elemen...
