Abstract

A stacked patch configuration is used to electromagnetically couple a GaAs MMIC chip to a patch antenna integrated in the lid of the MMIC package. The lid is formed using a liquid crystal polymer substrate. Presented is the first implementation that covers the E-band frequency range from 71–86 GHz for long-range wireless communications. Antenna gain is greater than 8 dBi using a short horn with straight sidewalls.
