Simulation and Experimentation Analysis of Dielectric Covers on Square Patch Antenna in Wireless Communications

In this paper the different dielectric covers affects on square patch antenna is investigated and compared their performance. The designed at 2.4GHz with arlon diclad 880 substrate. constant of substrate 2.2 thickness 1.6mm. or superstrates are used whose constants 2.2, 3.2, 4.8 10.2. simulated using Ansoft electromagnetic simulator such as HFSS. effect cover height (H) =0 antenna, result performance slightly decreased increase above increases patch, but optimum height, results which same without cover. uses to providing protections from physical damage, rain snow also protecting heat other environmental hazards. This specifications frequency in wireless applications.
