摘要：

This paper puts forward a low-profile, circularly polarized (CP), wideband Euler's Spiral Dielectric Resonator Antenna (ES-DRA) having a footprint of 0.68 lambda x 0.68 lambda x 0.096 lambda and operating in X and Ku-band (8.26-14 GHz). A cross-shaped aperture is used to couple the power from 50 Omega walking stick-shaped microstrip line to the ES-DRA. The antenna generates circular polarization radiation in the frequency band 10.47-11.69 GHz and has a peak gain of 8.1 dBic. There is a good matching between radiation and total efficiency in the operating band. The antenna can be put to use in weather mapping and detecting, long-range tracking radar and missile applications. The prototype has been fabricated and tested for experimental validation and the results are in good coherence with the simulated ones.
