DUAL BAND COMPACT MONOPOLE ANTENNA FOR ISM 2.4/5.8 FREQUENCY BANDS WITH BLUETOOTH, WI-FI, AND MOBILE APPLICATIONS

摘要

In this work, a dual bands omnidirectional monopole antenna is proposed. A planer Y-shaped patch is loaded on the top of the surface and a slot is loaded on the ground plane to obtained broad-band. Rogers RT/duroid5880(tm) substrate is used with dielectric constant 2.2 and loss tangent 0.0009. The results of the proposed antenna for the variation of width and length of the ground plane are investigated. Two licensed free frequency bands at 2.4 GHz and 5.8 GHz are obtained for WiFi and Bluetooth application. The measured frequency bands of 2.3-2.52 GHz at 2.4 GHz and 4.22-10.30 GHz with two resonant frequencies at 4.96 and 8.36 GHz are obtained. The peak antenna gain of 4.6 dBi at 2.4 GHz is achieved. Simulation has been done using MOM base Ansoft designer software. (C) 2017 Wiley Periodicals, Inc.
