Multiband Microstrip Antenna for 4G Mobile Application

Abstract

In proposed work which has been analyzed and designed on IE3D tools, we cut a different types of slot like Lslot, Z-slot, U-slot and finally got the result at our desired frequency that is for 4G application at 2300MHz. In this research, we achieved multiband which is a essential parameter of wireless communication. The VSWR, Return loss, Bandwidth, Directivity, Gain is acceptable for this application. We have VSWR = 1.18 & Return loss = -21.5 dB at 2270MHZ. For this design we use RT Duroid as a substrate material with dielectric constant 2.2. These characteristics make the designed antenna suitable for 4 G applications.
