Abstract :
A low-profile, switched-beam, end-fire antenna integrated with a novel microstrip-to-slot transition is presented. The antenna module consists of wire-bonded switch and PA integrated in liquid crystal polymer substrate package. The proposed transition exploits slow-wave techniques to transform a 50 Ω microstrip into a 110 Ω slot mode over 55 to 67+ GHz. The 10 mm × 10 mm active antenna 3 dB beamwidth is 55°/68° (E/H plane) in each switched state with an average 19 dBi peak gain over 55 to 67 GHz.
