Design and implementation of a filtenna with wide beamwidth for Q-Band Millimeter-Wave short range wireless communications

Abstract

An integrated millimeter wave filtenna is proposed for Q-band indoor short range wireless communications (IEEE 802.11aj). Comprising of a substrate integrated waveguide (SIW) filter and a printed angled dipole with a reflector, the proposed filtenna performs a bandpass response over 43.5-47GHz and the wide beamwidth larger than 120° in main cuts. The proposed filtenna and its counterpart without the filter are simulated, fabricated, and measured. By comparing the measured return loss and radiation patterns between the filtenna and the original antenna, it is concluded that the performance of the filtenna is kept nearly no change within the operating frequency band while the out of band signal is effectively filtered.
