The design opens a new dimension for the microstrip antenna design engineers by avoiding the necessity of cutting any slot within the radiating patch for getting the band notch characteristics. In our design the impedance bandwidth is obtained from 3.08GHz to 11.1GHz matching with the Federal Communication Commission (FCC) regulated band. The steps need to be adjusted properly to obtain the desired impedance bandwidth. The antenna is also found with a band rejection property from 4.5GHz to 7.2GHz for -10dB return loss.

frequency orthogonally polarized rectangular patch antenna
integrated with defected ground structure (DGS). A spiral-shaped DGS-integrated microstrip line enhances the port isolation of the antenna, while feeding the 2.45 GHz port, port-1 to the antenna and filtering out 3.0 GHz receiving signal from port-2.Similarly a rectangular shaped DGS-integrated microstrip line enhances the
port isolation of the antenna, while feeding the 3.0 GHz port, port-2 and filtering out the 2.45 GHz signal from port-1. The microstrip line at two different ports integrated with DGS restricts the high order harmonics signals coming from transmitter or receiver. The patch is excited through microstrip feed line of 75Ω line impedance. DGS-integrated microstrip line offers image impedance of 150Ω and it is controlled by DGS geometry. An experiment of investigating isolation between the ports has been performed by employing with and without DGS. Measurements show an improvement of more than 25dB in the port isolation when DGS integrated microstrip antenna.
