Abstract
A high gain bidirectional reflect-transmit array antenna for millimeter wave applications is proposed which combines the properties of transmitarray and reflectarray antenna. The bidirectional antenna array is composed of phase and amplitude modulating digital metabits. The digital metabit consists of a dipole with end loading printed on the top layer of the substrate and a slotted end-loaded dipole on the bottom layer. A bidirectional transmit-reflect array of dimensions 5.6 λo × 5.6 Ao is designed and fed by an antipodal Vivaldi antenna. A maximum broadside gain of 13.1 dBi is obtained at 28 GHz in both transmission mode and reflection mode simultaneously. The designed 1-bit transmit-reflect array finds its application in the 5G communication system.
