摘要：
A wideband (WB) and circularly polarized (CP) antenna is modelled, fabricated, and characterized. The wideband antenna comes with a conical dielectric resonator antenna excited by microstrip fed slot coupling mechanism. In addition to this, a set of tapered sheet is suspended on both sides of the feed line up to the WB slot to ensure circular polarization. From authors' point of view this kind of approach for CP is quite new in this domain. This proposed geometry is modelled with commercial finite element solver HFSS v13.0. The measurement results shows a wide band of 11.46 % (over 7.4 GHz-8.3 GHz) and 5.7 dBi peak gain. In addition to this, a circular polarization (AR < 3 dB) of 4.5% bandwidth is obtained over 7.65 GHz-8 GHz. In view of these results, this model satisfies the basic criteria for X-band wireless applications.
