A shaped-beam dielectric antenna
Abstract
An approximate method is developed to calculate the radiation of a rectangular dielectric block excited by a circular waveguide. The dimensions are optimized with respect to the E and H plane pattern shape difference over a wide range of microwave frequencies. A dielectric coating is then applied to improve input matching and bandwidth.
