摘要
In this communication, we present a new circularly-polarized array antenna using 2 x 2 linearly-polarized sub grid arrays in a low temperature co-fired ceramic technology for highly-integrated 60-GHz radio. The sub grid arrays are sequentially rotated and excited with a 90 degrees-phase increment to radiate circularly-polarized waves. The feeding network of the array antenna is based on stripline quarter-wave matched T-junctions. The array antenna has a size of 15 x 15 x 0.9 mm(3). Simulated and measured results confirm wide impedance, axial ratio, pattern, and gain bandwidths.
