A miniaturized dual band microstrip antenna for Worldwide interoperability microwave access and C band radio navigation

Abstract

Here a 26 x 32 x 1.6 mm3 sized dualband microstrip antenna that realized the frequencies 3.4Ghz and 6.7Ghz for the applications wimax and radionavigation respectively is designed. FR4 dielectric with permitivity 4.4 is the dielectric material used. The S11 in dB with standing wave ratio for the generated frequencies are -28.29 and - 23.01 with 1.08 and 1.15 respectively. It comprises of a rectangular slot on the patch to achieve impedance matching. The analysis of return loss, gain and radiation patterns was done using HFSS tool.
