A -45/spl deg//+45/spl deg/ dual polarized microstrip antenna for wireless communication

A novel -45/spl deg//+45/spl deg/ dual polarized microstrip antenna array for wireless applications within the 5.300-5.550 GHz range is designed and fabricated. The two ports of the antenna corresponding to -45/spl deg/ and +45/spl deg/ polarization are operated on the same frequency band. The simulations and experimental measurements of the VSWR and the isolation are presented. The relative bandwidth of 4.3% for VSWR <2 and isolation >16 dB are achieved.
