Group antenna with two polarisations and a common aperture, defined by a planar waveguide-fed slot group, and a linear short backfire group : CA 2177191 CA2177191C (en) 1995-06-06: 1996-05-23: Dual polarization common aperture array formed by a waveguide-fed planar slot array and a linear short backfire array High gain dielectric loaded exponentially tapered slot ... Dielectric loaded exponentially tapered slot antenna design. The ETS antenna is also known as flared notch antenna, is among one of the most promising antenna satisfying all requirements described in the technical challenges . It is fundamentally a planar traveling wave antenna with end fire radiation. Infrared Tapered Slot Antennas Coupled To Tunnel Diodes
Tapered slot antennas are also suitable to be used at high operating frequencies (greater than 10 GHz), where a long electrical length corresponds to a considerably short geometrical length. The main disadvantage of the TSA is that only linear polarization can be obtained with conventional geometries.
