Planar Circularly Polarized Antenna for UWB High Band Applications
In this paper, we propose the design of $1\times 2$ array circularly polarized (CP) slot antenna for UWB High band applications. The proposed antenna element is composed of three parts: a top metal that consists of L-shaped slot structure, a dielectric substrate (FR4), and a bottom floating metal layer. To realize a high gain toward the z-axis direction, the two antenna elements are arrayed, and each antenna is connected with the branched CPW (coplanar wave guide) transmission line. The simulated results of S-parameter, axial ratio, and the antenna gain of the $1\times 2$ array antenna are presented. The operation bandwidth of the proposed antenna is 1.10 GHz (9.35 GHz–10.45 GHz), and the relative bandwidth is 11.1%. The peak gain is 6.05 dBic at 9.9 GHz.
