Abstract
Various arrangements of transmit and receive shared-aperture array antenna systems are presented herein. The arrangements can include an antenna that includes: a planar substrate; a first row of a first plurality of transmit patches arranged on the planar substrate; a second row of a plurality of receive patches arranged on the planar substrate; and a third row of a second plurality of transmit patches arranged on the planar substrate. The first row, second row, and third row can be parallel and the second row can be between the first row and the third row.
