Abstract

This paper proposes a symmetrically stacked planar phased-array (SSPA) concept to fundamentally improve the spherical coverage CDF of millimeter-wave cellular handsets featuring full metallic frames. The proposed SSPA achieves three independent main beam directions (pm z- textaxes /+x-textaxis) by adjusting the input weighting matrix of the SSPA. It has been experimentally verified that the proposed SSPA concept significantly improve the spherical coverage CDF of the present-day cellular device without structural deformation of the metallic frame. The measurement results confirm that the proof-of-concept model achieves a maximum beamsteering angles of ±43° (peak gain: 8.4 dBi) in the broadside modes and ±33° (peak gain: 5.1 dBi) in the endfire mode. The use of SSPA modules improve the spherical coverage CDF more than 5 dB at the 25th percentile compared to the reference model.
