Design of a Novel Coaxial Feed Triple Frequency Patch Antenna with Slots and Shorting Pin

This paper presents a detailed explanation on the design of a novel triple frequency rectangular slot antenna for wireless local area network (WLAN) applications in IEEE 802.11b/g/a systems. This proposed antenna operates in ISM band at frequency of 2.4 Ghz and also in C band at 4.85 Ghz AND 6.1Ghz. The antenna has been designed and simulated on a foam substrate with dielectric constant of 1.06 and a thickness of 7 mm. The design is analysed by Finite Element Method based HFSS Simulator Software (version 13.0) by which return loss, 3D polar plot and Gain of the antenna are computed. In addition, the measured results show good radiation characteristics at the three operating frequencies, proving the dual-band operation of the proposed antenna.
