E-shaped patch antenna at 4.87 GHz

This paper represents designing & analysis of E-shape microstrip patch antenna for wireless communication. Low volume, low profile configuration, easily mounted, light weight, low fabrication cost is the advantages of this antenna. The operating frequencies of antenna are 2.97 GHz and 4.85 GHz, the substrate FR4 is used for proposed antenna with dielectric constant 4.2 and thickness of 1.7mm. Two parallel slots are cut to perturb the surface current path, which provides a bandwidth of 11%. The E-shape has return loss of −28 dB of and −14.03 dB at operating frequencies 2.97 GHz and 4.85 GHz respectively. Designing and simulation of this antenna has been done by the help of HFSS Software. This antenna is fed by a co-axial probe feeding. In this paper, the effects of different types of antenna parameters studied.
