Design optimization of 15–34 GHz Ultrawideband Tapered Slot Antenna Array with Defected Ground

Design and optimization of 15–34 GHz ultra wideband tapered slot antenna array with defected ground is proposed in this paper. Systematic approach for design of single element antenna followed by performance analysis over curved surfaces has been reported. After achieving the desired performance over the required band for both planar and conformal cases, studies on array analysis has been performed. The maximum realized gain of the single antenna shows a minimum of 8 dBi from 15 GHz to 34GHz. The gain has been significantly increased through array approach. The paper also reports the axial ratio analysis towards study of polarization effect. The analysis shows that, the proposed antenna array is suitable for wireless systems that can be used in aerospace platform.
