Abstract :
A new type of dielectric surface-wave antenna (DSWA) has been proposed using a tapered cylindrical dielectric structure. The structure is radially tapered in permittivity to produce a directive endfire beam that is omnidirectional in the azimuth direction. Unlike a dielectric resonator antenna (DRA) that uses a cavity mode to achieve radiation, this antenna uses a radially-propagating surface wave to create an endfire beam.
