Abstract :
A planarly fed UWB leaky lens antenna is presented integrated with wide band transmit and receive front-end electronics, to be used in a SAR-based imaging system. The unique non-dispersive characteristics of this antenna over a very wide bandwidth, together with the dual band front-end electronics based on `off the shelf´ components and integrated using standard PCB technology makes them very attractive as transmit-receive element for a MIMO array configuration. Design and measurement results of the leaky lens antenna characteristics are presented, and design considerations for the integrated mm-Wave electronics are discussed.
