Abstract
A multilayer antenna structure configured to receive Global Navigation Satellite System (GNSS) and augmentation signals. The antenna includes a microstrip patch radiation element disposed at a top layer and a ground plane forming a first interior layer, the ground plane including at least two coupling apertures, and the ground plane isolated from said radiation element by a low loss dielectric. The antenna structure also includes a bottom layer, the bottom layer is isolated from the ground plane by another dielectric; at least two feed lines operably connected to a hybrid coupler disposed on the bottom layer; and an active circuit on the bottom layer, a first port of said active circuit operably connected to the hybrid coupler.
