Abstract
In this paper two triple-band monopole antennas are proposed for portable wireless applications such as WiFi, WiMAX and WLAN. Two different geometrical structures are used for the radiating elements of these antennas, each printed on a low cost FR-4 substrate. Truncated metallic copper ground is used to attain optimum radiation pattern and better radiation efficiency. The frequency of the antennas is reconfigured using a lumped-element switch. The proposed antennas covers three frequency bands 2.45, 3.50 and 5.20Â GHz depending upon the switching conditions. Both antennas works with an optimum gain (1.7-3.4Â dB), bandwidth (6-35%), VSWR (<1.5) and radiation efficiency (85-90%). Due to its affordable size (1.6Â ÃÂ 35Â ÃÂ 53Â mm3), the antennas can be used in modern and portable communication devices such as laptops, iPads and mobile phones. The prototype of the antennas are fabricated and the measurements and simulations are found in close agreement.
