A new approach for a dual-polarized low cost patch antenna with low cross- polarization, high bandwidth and high isolation

In this paper a new approach for a dual-polarized broadband patch antenna is presented. A novel feeding approach enables a high -10dB bandwidth up to 21 % as well as an isolation more than -29 dB. The realized antenna gain is > 6 dBi in the frequency range of 1320 MHz to 1680 MHz. Additional, due to the reflector shaping, a low back radiation is achieved. Since standard components and FR4 material are used, the antenna concept enables an effective low cost antenna production.
