Dual-Band Antenna For Fixed Satellite Service With Amateur Radio

In the proposed paper, we presented a dual-band applicative antenna for satellite communication. According to WARC-92, a band with 13.75-14.0 GHz has been allocated for FSS considering a primary basis. This band covers by our proposed antenna and at the same time, another band which is also a part of satellite communication term as 3-centimeter wave i.e. operating frequency is 10GHz. This band is allocated to amateur radio and satellite use as far as a secondary basis is considered. The antenna size is 35.5x35x0.8mm3and the substrate is Rogers RT-Duroid with relative permittivity (€r) of 2.2. The reflection coefficient| S11| observe at the 10 GHz is -31.43 dB, at the 13.75 GHz is - 18.14dB and at 14.0GHz is -13.8 dB. The bandwidth covered by the first band i.e. 10 GHz is 100 MHz. The second band resonating from 13.2 GHz (lower Ku band) to 14.4 GHz (upper Ku band) under which our required band is easily covered with an ample amount of return loss. The peak gain of 7.642 dB and 6.81 dB is observed at respective bands. The simulation is done with HFSS software.
