A very small Dual-Band MIMO Slot Antenna for WLAN and Wi MAX Applications
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2018, Vol 13, Issue 6
Abstract
A very small dual band two element MIMO antenna for wireless local area network (WLAN) and Worldwide Interoperability for Microwave Access (WIMAX) applications is presented in this project.A microstrip line-fed antenna with two quarter wavelengths slots of different lengths, which radiate at 2.5GHz and 5.6GHz, is used as an antenna element. The antenna is designed on 1.6 mm thickness FR-4 substrate with Ɛr=4.4 .Since WiMAX application is divided into two categories based on its radius of coverage area, the antenna design is varied by shifting the ground slot to new coordinates and resonant frequency is attained at 17.2 GHz for larger coverage area (>100feet).For smaller coverage area of WiMAX, the frequencies 2.5GHz and 5.6GHz would give the required response. The desired antenna design is achieved using HFSS 13.0. The antenna occupies an overall area of 24x25 mm2 . The antenna elements are fed by two 50 Ω stepped microstrip lines ,which is used as a simple decoupling network, based on a wide slot and a pair of narrow slots, to achieve good isolation (better than 20 dB) between the ports. The antenna is designed Moreover, the Envelope Correlation Coefficient (ECC) of the proposed antenna is within the acceptable limit. By placing a ground slot in a finite antenna ground plane, other reconfigurable features can be included. Thus such antennas that are small in size and have multiband capability can be promising for many wireless applications.
