摘要

A new hybrid-antenna that is capable of wide-bandwidth operation and is small size is presented. The structure of the proposed antenna consists of a cylindrical dielectric resonator, metallic posts that are embedded in the resonator, and a rectangular patch. The proposed design generates three resonances: the full-cylindrical HE, half-HE-like mode, and radiation by the patch antenna. An electromagnetic analysis using a finite integration method (CST microwave studio) was performed to investigate the resonances. Furthermore, a prototype of antenna has fabricated for the experimental verification. The simulation results are in close agreement with the experimental findings. The proposed antenna offers a fractional bandwidth of 16.5% at the centre frequency of 9.27 GHz and a peak gain is >4.56 dBi in the matching band.
