Abstract
In this paper, a microstrip line-fed antenna with a Spidron fractal shape in the ground plane is presented. The proposed antenna is able to work in two frequency bands i.e. from 6.27–6.97 GHz and 15.73–19.38 GHz with corresponding resonant frequencies of 6.57 and 17.61 GHz. The impedance bandwidth obtained for both operating bands is 0.703 GHz and 3.64 GHz respectively. High gain of 9.04 dB and 7.82 dB for both bands is obtained. Due to the Spidron defected ground structure, the decrease in the resonant frequency can be seen. The volumetric dimensions of the proposed antenna are highly compact (36 mm×36 mm×0.762 mm) and hence, can be easily integrated with other microwave circuits. The proposed structure covers super-extended C-band, partial K-band and Ku-band, hence suitable for several satellite transmission applications. The proposed antenna designs have been simulated using ANSYS HFSS. The design concepts, rules and procedure for the proposed antenna are also discussed in detail.
