Design and performance enhancement of a modified corrugated Vivaldi micro-strip patch antenna for remote sensing applications

In this study, a practical modified corrugated Vivaldi micro-strip patch antenna (MC-VMSPA) is designed for the use of remote sensing applications such as through-wall radar applications. First, the basic design of Vivaldi micro-strip patch antenna (VMSPA) is optimized for the targeted band of frequencies of the through-wall radar applications. Then, a modified design that consists of a series of parasitic radiating patches on the substrate antenna is proposed to enhance the operational bandwidth of the radar and to attain the required directiveness with a practical gain value. The outcome after the design and the optimization of the proposed antenna is presented in comparison with the classical VMSPA. Analyzing the optimized design in terms of antenna parameters demonstrates the effectiveness and the availability of the designed MC-VMSPA for the use of remote sensing radar applications.
