A vertical-strip-fed dielectric resonator antenna exhibiting broadband circular polarization characteristics is presented. A broad 3 dB axial ratio bandwidth (ARBW) is achieved by combining multiple orthogonal modes due to the use of a special-shaped dielectric resonator. The proposed antenna is fabricated to evaluate its actual performance capabilities. The antenna exhibits a measured 3 dB ARBW of 44.2% (3.35-5.25 GHz), lying within a -10 dB reflection bandwidth of 82.7% (2.44-5.88 GHz). The measured peak gain within 3 dB ARBW is found to be 5.66 dBic at 4.8 GHz. The measured results are in good agreement with the simulated results.
本文提出了一种具有宽带圆极化特性的垂直带状馈电介质谐振器天线。由于使用了特殊形状的介质谐振器，通过组合多个正交模式实现了较宽的3 dB轴比带宽（ARBW）。制作了所提出的天线以评估其实际性能。该天线测得的3 dB ARBW为44.2%（3.35 - 5.25 GHz），位于82.7%（2.44 - 5.88 GHz）的 -10 dB反射带宽内。在3 dB ARBW内测得的峰值增益在4.8 GHz时为5.66 dBic。测量结果与模拟结果吻合良好。
