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