Abstract :
A broadband microstrip antenna for DBS (direct broadcasting by satellite) reception is presented. DBS in Europe requires a linear polarisation, a relative bandwidth of 17.5% (from 10.70 GHz to 12.75 GHz) and a cross-polarisation less than -20 dB. According to these requirements, a dual polarised aperture coupled microstrip antenna was designed in two steps. In the first step, a new disposition of the feeding lines was used. A single patch element permits to obtain a bandwidth of more than 26% whereas an additional patch element as a parasitic element is currently used in the literature to increase the bandwidth. In the second step, a perforated patch element was used in order to ameliorate the cross-polarisation.
