摘要

The return loss of tradition eleven antennas is large and the reflected energy will effect circular polarization characteristics. In this paper, an eleven antenna loaded with lumped resistances of 470 ￡2 is presented for square kilometer array (SKA) radio telescope application. The eleven antenna is a traveling wave antenna and the lumped resistance is loaded to absorb the reflected energy. The proposed eleven antenna has a bandwidth from 0.4 GHz to 2 GHz for VSWR < 2.1 : 1. The 10 dB main beam is about 102°. Compared with tradition eleven antennas, only about 5% efficiency is reduced. A experimental model is fabricated to validate the analytical results. Obtained experimental results are in good agreement with numerical data.
