摘要
In this work, a new microstrip circularly polarized leaky-wave antenna is presented for X -band applications. The design of the proposed leaky-wave antenna is inspired by the conventional 3 dB branch-line coupler. The geometry of the unit cell of the proposed leaky-wave antenna is realized by removing the two collinear feed lines of the branchline coupler. The open stopband is eliminated by optimizing the geometry. The proposed leaky-wave antenna provides impedance bandwidth with vertical bar S-11 vertical bar < -10 dB between 8.2-11.1 GHz. The bandwidth corresponding to axial ratio < 3 dB is 9.4-10.3 GHz. The antenna radiates in the broadside at 9.9 GHz with 14.1 dBic gain.
