A Novel Violin Type UWB Patch Antenna for X & Ku Bands using metamaterial: A Review

The main motive of this paper is to design an antenna using metamaterial that provides lower return losses, high gain and good performance in X and Ku Bands. The antenna is a violin shaped structure and resonates at 9.4 GHz and 14.2 GHz. The center frequency Fr is 10 GHz. The design is finalized by employing metamaterial based split circular ring resonator. RT Duroid 5880 is used as substrate and patch is design on 20 x 20x 1.588 mm substrate body. Comparison is also studied by employing (CSSR) Complementary Split Rectangular structure and different results have been simulated on HFSS software showcasing the return loss and VSWR. The E and H patterns lies on same plane and good gain is achieved up to 16dB. The simulated results show –15 dB and –21 dB impedance bandwidth for X-band applications which is in range of 9.42 GHz and for Ku-band applications which is in range of 14.2 GHz. Circular notch is also inserted to have good bandwidth. The radiation efficiency is found to be approximately 98% for the bandwidth. The VSWR is also less than 2 for both bands which makes it suitable for applications in satellite and radar communications.
