Abstract

The primary object of this paper is to investigate the polarization mismatch effects between transmitter and receiver antennas in noncontact monitoring applications. It is shown that circularly-polarized antennas have better performance compared to similar linearly-polarized ones in the presence of the human body. A novel y-slot wideband CP antenna is proposed. The antenna consists of a u-shaped feed, a y-slot, and a parasitic stub. Simulation results show a bandwidth of 82% (3-7.2 GHz) for VSWR<2:1 with a 3 dB axial ratio (AR) bandwidth of 33% (4.6-6.4 GHz). The proposed antenna has a low profile with an overall size of 28 mm×28 mm×1.6 mm.
