Abstract

In this letter, we present a Ka-band 8-element E-plane beam steering/shaping phased antenna array (PAA) using antipodal elliptically tapered slot antenna (AETSA). The power feeding network, phase shifter and antenna element were fabricated on a single low cost PCB substrate to avoid the extra loss caused by connection of different circuit pieces and for easier integration and easier fabrication. The system achieved wide scanning angle, which is from −21° to +24° and the 3 dB beamwidth is widened by 10°, the latter being the requirement for plasma imaging application.
