Summary:
The tremendous growth in wireless networking demands design of low cost, compact, single layer antennas for efficient communication. Wireless router plays a major role in wireless local area networks (WLAN) to facilitate interconnection between PCs, laptops, smart phones and other wireless modules. The major challenges in the design of antennas for these applications include miniaturization, low cost and single layer design while maintaining impressive radiation characteristics. The IEEE standard specification for 2.4GHz WLAN is from 2400MHz - 2485MHz and 5.2 hyperlan spectrum includes frequency from 5150MHz ? 5350MHz. At present many other systems such as cordless phones, microwave oven and Bluetooth accessories also utilizes the 2.4GHz spectrum which resulted most of the WLAN systems utilize 5.2GHz band for efficient, distortion less communication. In this scenario a single, compact antenna supporting both these WLAN bands is of important significance and this has attracted many researchers around the world [1,2,3,4] In this paper, the authors present a compact dual band, low cost, single layer antenna suitable for 2.4/5.2GHz WLAN applications. The CST Microwave Studio? [5] is utilized for the optimization and analysis of the antenna. A prototype of the optimized design which meets the design goals as per the IEEE 802.11 specification is fabricated and experimentally characterized. Details of the proposed antenna design, along with the simulated and measured results are presented and discussed.
