Antennas for Broadband Microwave/mm-Wave Communication Systems
An overview is presented of the antenna and microwave circuit research, applicable to broadband communication systems, carried out by the Directorate of Antennas and Integrated Electronics (DAIE) of the Communications Research Centre (CRC). This paper concentrates on the antenna hardware research and development within DAIE. Recent research in antenna hardware has been focused on printed multi-layer arrays, dielectric resonator antennas, flat reflectors, active circuit integration, and low loss feed networks. The antenna elements presented have operating bandwidths varying from 5% to 28% and hence are all suitable candidates for various broadband communication systems. The microwave circuit division is focused on monolithic microwave integrated circuits (MMIC) and miniature hybrid microwave circuits (MHMIC). A prototype K/Ka-Band transceiver demonstrating these technologies is presented.
