As an example an inset feed microstrip antennas is designed to
resonate at 10 GHz frequency with dielectric constant ("r) = 4:7,
substrate thickness h = 1:588 mm, L = 6 mm, W = 8:88 mm on a
ground plane. All dimensions of the antenna is in mm. The length and
the width of the patch are calculated initially by the relationships (1){
