Abstract

A novel millimeter wave antenna array with harmonic rejection property is designed for wireless power transfer applications. The proposed antenna is a proximity coupled dual-polarized antenna with a coupled dual-mode open-stub resonator in the feed for suppressing higher harmonics. Odd and even mode resonance of open-stub loaded resonator is tuned to the second and third order harmonics of the antenna element respectively to realize the configuration as a dual-band reject filter. The designed dual-polarized antenna has a bandwidth of 2.23 GHz (centred at 35 GHz) and worst case isolation of 20 dB between the two feeds. The antenna element has a high gain of 7.76 dB. The proposed four-element antenna array has a very good gain of 12.4 dB, dual polarization, and harmonic rejection which makes it a good solution for wireless power transfer (WPT).
