Abstract

A broadband right-hand circularly polarized (RHCP) cross-type traveling wave antenna array is proposed for High-Rate Close Proximity (HRCP) point-to-point (P2P) wireless communication system at 60 GHz. Instead of low temperature co-fired ceramic (LTCC) technology, a single-layer structure of the proposed 2x1 element antenna array is fabricated with a conventional printed circuit board (PCB) process, to provide low manufacturing cost and low profile (0.05 λ0 at 60 GHz). A wide impedance bandwidth (57-64 GHz, VSWR < 2) and broad RHCP bandwidth (57-64 GHz, axial ratio (AR) < 3 dB) are achieved. The RHCP gain is higher than 6 dBic in the entire operating frequency band (57-64 GHz).
