This article presents a ring‐shaped antenna array for multistatic microwave breast imaging. The antenna element uses a compact double‐ridged waveguide probe operating from 3 to 6 GHz, and its radiation performance is experimentally verified in a lossy immersion liquid with a pass loss of −0.67 dB/mm. Eight antenna elements are integrated into a 150 mm diameter ring structure that sufficiently surrounds the breast. The ring structure has a 15 mm groove between the antenna elements to reduce the electromagnetic influence of the ring wall to less than 0.5 dB.

用于多静态微波乳房成像系统的环形天线阵列

本文介绍了一种用于多静态微波乳房成像的环形天线阵列。该天线元件使用紧凑的双脊波导探头，工作频率为3至6 GHz，并在有损耗的浸没液体中通过了-0.67 dB / mm的通过损耗，并通过实验验证了其辐射性能。八个天线元件集成到直径为150 mm的环形结构中，该结构充分围绕乳房。环形结构在天线元件之间具有15毫米的凹槽，以将环形壁的电磁影响减小到小于0.5 dB。
