Design of Dual-Polarized Microstrip Array on L-Band

A dual polarized navigation microstrip array which is used in L-band is proposed in this paper. The unit uses the structure of H-slot coupling microstrip and the array is shaped by Taylor expression. Both of the antenna unit and the array are optimized and manufactured. The simulated and measured results are also given in the paper. The 3dB beam width of the L-band array is less than 21.64° and the level of cross polarization in the beam width is less than 29.76dB. Both of the main beam efficiency of the two polarizations is more than 95%.
