Abstract

A novel and compact CPW fed triband antenna suitable to support WLAN and WiMAX communications in 2.4/3.5/5.5 GHz bands is reported. The 5.5 GHz band extends from 4.9 to 5.94 GHz. So the proposed antenna can support the use of 4.94-4.99 GHz band allotted for fixed and mobile service (except aeronautical mobile service) for use in support of public safety and 5.85-5.925 GHz band for Dedicated Short-Range Communications (DSRC) services in the Intelligent Transportation System (ITS) radio service. Metallic radiating stub extending from the feed is used to excite the resonance at 2.4 GHz. An open slot in the stub and a pair of open slots in ground plane are used to excite the other resonances. An arc shaped parasitic element is also included in the design for improved radiation performance. The proposed antenna geometry is developed on FR4 glass epoxy substrate with relative permittivity 3.8 and loss tangent 0.02. The geometry is developed and optimized using High Frequency Structure Simulator and experimentally validated the results. Performance comparison of the proposed antenna with similar antennas in literature is presented. Measured radiation patterns and gain are also included in this paper.
