宽带宽轴比圆极化天线阵列
A broadband wide axis ratio circularly polarized antenna array
摘要
Abstract
In this paper,a 2×2 broadband wide axis ratio circularly polarized microstrip antenna array is proposed.The antenna unit is fed by a microstrip line-metallized perforation and consists of a square patch with an orthogonal gap and four curved patches.By optimizing the arc size,the area of the four arc patches is equal to the area of the orthogonal slit,thus ensuring the effective radiation area of the antenna and im-proving the radiation efficiency.The designed microstrip antenna units are formed into 2×2 arrays to en-hance gain and improve radiation directional deflection.Measured results of the fabricated antenna array show that-10 dB impedance bandwidth is 35.7％(29～41.6 GHz)and 3 dB AR bandwidth is 26.6％(29～37.9 GHz)with a peak gain of 11 dBic.Cross-polarization levels are below 20 dB in all three CP major modes.关键词
