Design and Study of QWT FED Microstrip Patch Antenna at 6.5 Ghz Application

Abstract

We design the QWT fed micro strip patch antenna at 6.5 GHz application. The first stage is to design square shaped patch Antenna and feeding is done with the QWT feed to match the impedance of 50 ohm. In the simple rectangular microstrip patch, two slots in the patch have been made. The two slots have been made along two corners of the patch. The parametric changes provide the result for 6.5 GHz applications. The frequency 6.5 GHz is chosen because the frequency gives extremely high performance i.e the return loss response exhibiting the characteristic three transformation zeros exceeds 40 dB.
