Enhancement of Gain of Printed T MonopoleAntenna Using Uniplanar EBG for ISM Band(2.4GHz) Applications

A novel and simple printed T monopole antenna with EBG Structure is proposed. The antenna comprises T-shaped monopoles of different sizes, which generate resonant modes for the desired 2.4GHz frequency range. The proposed antenna has a low profile and can easily be fed by using a 50 microstrip line. Prototypes of the proposed antenna designed for WLAN operations in the 2.4GHz bands have been constructed and tested. Good radiation characteristics of the proposed antenna have been obtained. Effects of varying the monopole dimensions and the ground-plane size on the antenna performance have also been studied. To introduce uniplanar EBG Structure for enhancement of gain of the antenna is been done. Effects of varying EBG Structure and antenna performance have also been studied using HFSS Sotfware
