Research paper DESIGN AND SIMULATION OF THE SLOTTED E-PATCH MICROSTRIP DUAL BAND ANTENNA FOR WIFI APPLICATIONS Alfred-Abam Edmund Fubara icyfubu@yahoo.com Raifu Isola Salawu College of Engineering, Department of Electrical & Electronics Engineering BELLS University of Technology Nigeria, Km 8, Idiroko Road, Ota, Ogun State Email: risalawu@gmail.com Abstract Microstrip patch antennas have become more popular in portable wireless communication systems. These antennas are light in weight, low profile, support wideband and low in the cost of fabrication. Wireless communication deals with antenna performances, which has led to several researches on dual band and wideband antennas in which these antennas are embedded into an RF printed circuit board, so they cannot be seen from the device point of view. The E-patch antenna is one of a microstrip antenna type currently under research and improvement which has led to quite a number of them already been implemented in satellite communications operating in KU, X- band and S-band. In this presentation, the E-patch is designed to receive Wi-Fi signals. It operates in a dual band mode and resonates at frequencies of 2.4 GHz and 5.8 GHz of which the operating frequencies can be useful for high performance of digital communication with less noise interference. The Electromagnetic simulator software ADS will be used for the simulation of the E patch for performance enhancement and the parameters to be studied in the simulation are impedance, return loss, VSWR, gain, bandwidth and radiation pattern In which after the simulation phase, the E-patch antenna will be fabricated and tested. Therefore At the end of this research all the parameters will be analyzed and compared with the practical result. Keyword: Microstrip patch antenna, Return loss, VSWR, Dual band, ADS software. 1. Introduction 1.1 Historical on the Evolution of the Microstip Antenna In the late 1970s microstrip antenna embarked on its journey and by the beginning of 1980s microstrip antennas were fully in operation for antenna design and modeling (Fiedziuszko, 2001). In the last few decades microstrip antennas or printed antennas have been extensively used because of their characteristic advantages like low profile, light weight, low cost and ease of fabrication. A microstrip antenna consists of a conducting or radiating patch on one side of
