Abstract

r exploring the possibility of dual frequency response, a higher order mode frequency response in the air suspended design of a wideband E-shape microstrip antenna is studied, by appropriately decreasing the air gap.The decrease in the air gap realizes the impedance matching at higher order TM12 mode which along with the fundamental TM10 mode,gives dual frequency response. On an air suspended FR4 substrate with total thickness of 0.043λg, optimized single patch configuration yields dual band response at 2427 and 5730 MHz giving frequency ratio of 1:2.36. It yields impedance bandwidths of 6.6 % and 4.8% at two frequencies with respective broadside gains of 6.8 and 2.1dBi. The proposed configuration satisfies the requirements of 2.4/5.8 GHz WLAN applications. Parametric formulations are proposed for various antenna dimensions. The MSAs redesigned using them at given fundamental mode frequency yield a similar dual band response.
