Abstract

A phased array antenna panel includes a central radio frequency (RF) front end chip, neighboring RF front end chips, and an antenna. The antenna has a proximal probe and a distal probe. The proximal probe has one end at a near corner of the antenna adjacent to the central RF front end chip, and reduces an insertion loss in signals processed by the central RF front end chip. The distal probe has one end at a far corner of the antenna adjacent to one of the neighboring RF front end chips, and increases the isolation between signals processed by the central RF front end chip and signals processed by the one of the neighboring RF front end chips.
