Abstract: An analytical model of Edge Feed Micro Strip Stacked Patch Antenna (EFMSSPA) with twin slots operating at 5Ghz frequency is proposed and this lies within the microwave C-band (4-8 GHz). Micro strip Patch antennas (MSPA) with simple making procedure are preferred because of light weight, low profile low volume and easy to fabricate. These are used for satellite communication, wireless communication, medical, military systems and microwave radar applications. The antenna parameters like return Loss (S11), Voltage Standing Wave Ratio (VSWR), Gain and Directivity have been studied in this paper. The scale of the antenna 37.2*61.94*1.6mm3 has been increased by applying the Parametric Analysis. A unsighted trial and error means of analysis is take up to study the effects of twin slots on the patches. This Edge Feed Micro Strip Stacked Patch Antenna (EFMSSPA) with twin slots is designed using computer simulation Technology (CST) Microwave Studio. The CST Microwave Studio helps in understanding the features like Gain, Directivity, Return Loss (S11) and Voltage Standing Wave Ratio. The design process of an EFMSSPA and EFMSPA (Edge Feed Micro Strip Patch Antenna) is obtained by using FR4 Epoxy having a dielectric constant of 4.3. The Patch width (PW) and Patch length (PL) of an antenna are 18.43mm and 13.92mm the twin slots in the patch and stacked Patch placed with 3mm air gap above original patch increases the Return loss (S11), Gain and Directivity. A comparison of EFMSPA and EFMSSPA is considered and proved that EFMSSPA exhibits good results than EFMSPA.
