Size Reduction of Rectangular Dielectric Resonator Antenna with Symmetric Radiation Patterns and Low Cross Polarization
By
Progress In Electromagnetics Research Letters, Vol. 21, 159-167, 2011
Abstract
A 50% size reduction of the rectangular dielectric resonator antenna (DRA) is achieved by introducing shorting posts at the edge of the DRA in this paper. By choosing proper height of the shorting posts, the radiation pattern in E-plane maintains almost the same shape as the conventional rectangular DRA. The cross polarization can also be controlled to be a relative low level. By adding an open stub in the feed line, the proposed antenna has almost the same resonant frequency with the conventional rectangular DRA. The measured results for the constructed prototype are also exhibited and discussed.
