An Inverted-L Monopole Array With High Beam Coverage for Antenna-in-Package Modules at the 151.5–164 GHz Band

IEEE Access
An inverted-L monopole radiating element is proposed for antenna-in-package modules at the 151.5-164 GHz band. Its radiation pattern is half-isotropic and is well-suited for phased arrays for mobile communications.
