本文提出了一种具有倒F形微带馈线和两个相连的矩形缝隙的宽带圆极化缝隙天线。该天线提供了一个紧凑的尺寸（以前提出的缝隙天线具有类似的AR带宽几乎是两倍的大小），而不采用过孔或其他无源元件的宽3 dB轴比（AR）带宽。测得的AR带宽为83.5%（4.3和3-7.3 GHz），与测得的92.6%（5和2.9-7.9 GHz）<inline-formula><tex-math notation="LaTeX">的S_{11}$</tex-math></inline-formula>带宽完全重叠。
In this communication, a broadband circularly polarized slot antenna with an inverted-F-shaped microstrip feed line and two linked rectangular slots in the ground plane is proposed. This antenna offers a wide 3 dB axial ratio (AR) bandwidth in a compact size (previously proposed slot antennas with a similar AR bandwidth are almost double in size) without employing vias or other passive components. Measured AR bandwidth is 83.5% (4.3 and 3–7.3 GHz) which is completely overlapped by the measured <inline-formula> <tex-math notation="LaTeX">$S_{11}$ </tex-math></inline-formula> bandwidth of 92.6% (5 and 2.9–7.9 GHz).
