摘要：
In this article, a four-element multi-layer multi-permittivity (MLMP) cylindrical dielectric resonator antenna (CDRA) for broadband application is proposed. The proposed antenna provides the measured input impedance bandwidth of 58.1% (at resonance frequency 4.03 GHz) from 3.48 GHz to 5.82 GHz for input reflection coefficient (S11) less than 10 dB. The measured average gain is 4.82 dB in the frequency range of 3.48 to 5.82 GHz. The design provides consistent omnidirectional characteristics and low cross polarization within the operating band. Design details of the proposed antenna and the results of both simulation and experiment are presented and discussed. (c) 2012 Wiley Periodicals, Inc.
