Abstract
In this work, an aperture-coupled patch array antenna with wideband characteristics was designed and arrayed in a $4{\times}1$ S-band. The designed antenna structure consists of two layers, and it possesses wideband characteristics achieved using coupling between the two layers. The first layer is comprised of four radiation patches and the second layer has an aperture and a ground plane. The antenna structure possesses 15 % wideband characteristics and the center frequency is at 3.2 GHz. A phase shifter was added to the array antenna to enable beam steering. The proposed phase array antenna was fabricated and measured. Our proposed design enables beam steering up to $35^{\circ}$.
