The leaky lens: a broad-band fixed-beam leaky-wave antenna [PDF]
IEEE Transactions on Antennas and Propagation, 2005 A novel type of leaky-wave antenna is presented. Differently from previously reported leaky-wave antennas, it is characterized by a constant beam direction over a very wide range of frequencies. The radiation originates at a slot etched at the interface between air and a dense dielectric, which is shaped to form a cylinder of elliptical cross sections ...
