A rectangular microstrip patch antenna with multilayer substrate structure is designed in this paper. The designed antenna is analysed for the multilayer substrate structure. The height of the one dielectric substrate is taken as 1.6mm. Hence different antenna characteristics such as gain, bandwidth, return loss, directivity and VSWR are analysed four layer structureof the dielectric substrate. The resonant frequency of the designed antenna is 2.4 GHz. The dielectric substrate material used to design the antenna is FR4-epoxy having a dielectric constant of 4.4. The designed antenna has a bandwidth which covers the frequency band of WLAN applications. It is observed that the return loss of the antenna changes significantly with the layered structure of dielectric substrate. A return loss of -28.28 dB is achieved for the four layer substrate structure of the designed antenna which is much greater than the single layer structure. Microstrip line feeding method for energizing the antenna. Voltage standing wave ratio for the designed antenna is less than 2.The antenna is designed and simulated with Software High Frequency Structure Simulator (HFSS 13.0).
