Design and Analysis of E Shape Defected Ground Antenna Using Matlab

This paper presents the design of E shape defected ground antenna at 4.75 GHz using matlab simulation & CST. The operating frequencies can have the same polarization plane. This antenna can be considered to consist of two connected resonators of different sizes. E shape microstrip patch antenna defected ground and without defected ground is analysed using Matlab and CST software comparison is made between them. This antenna is based on a thickness of 1.6mm Flame Retardant 4 (FR-4) substrate with a dielectric constant of approximately 4.4.
