C Band Dual Polarized Low SLLArray Antenna

This paper designed a higher isolation,dual polarization,lower SLL planer array antenna.The unit of this array antenna is composed by pyramidal horn antenna.pyramidal horn antenna can get higher gain.use air microstrip line in designed of array feed,can be achieved lower loss,pyramidal horn antenna is taken as the air microstrip probe can get higher polarize-isolation.Using Taylor weight Realized-23dB SLL in design array antenna,and using reversal phase technology can further improve the polarized isolation and cross polarization.The result of simulation and measurement indicates that,with 6GHz±200MHz,VSWR is less than 2,the gain of array is more than 23dB,cross polarization level is less than-30dB
