An antenna assembly can be configured for RF communications. The antenna assembly can include a ground plane disposed on a substrate. The antenna assembly can include a patch antenna structure spaced apart from the ground plane. The antenna assembly can include one or more grounded posts coupled to and extending from the substrate. The one or more grounded posts can be arranged along at least a portion of a periphery of the patch antenna structure. The patch antenna structure can emit a radiation pattern based at least in part on a transmit signal. The radiation pattern can induce a resultant field in the one or more grounded posts to adjust a characteristic of the radiation pattern.

A patch antenna array system is provided. The patch antenna array system can include a plurality of patch antennas oriented with respect to each other to provide a nearly symmetric radiation pattern over a range of frequencies, such as from 1500 Megahertz (MHz) to 1700 MHz. The patch antenna array system can include a sequential phase feed network that is in communication with the plurality of patch antennas. The sequential phase feed network can be configured to provide a radio frequency (RF) signal to each patch antenna of the plurality of patch antennas such that the patch antenna array system has an axial ratio of less than 1 decibel (dB) over the range of frequencies.
