I have to design a microstrip inset fed patch antenna that resonates at 12.1GHz using a glass substrate of dielectric constant= 4.8 and effective dielectric constant=3.5, I found out my patch length= 6.5 mm and patch width= 8.26 mm, and inset length(inset distance from the edge toward the center of the patch)= 1.84 mm- does these sound right, as the measurements indicate that the antenna is going to be very small?? I am having problem with designing the inset, what should be the width of the 50 ohm transmission line feed and the inset gap length- is there any equation to find them?
