Abstract

In this paper, a Multiband-Frequency-Reconfigurable Antenna with a small compact size (20×35×1.6 mm3) is presented. The designed antenna can work effectively under the following modes: two modes of single band and one mode with dual bands. The reconfigurability has been achieved accurately by switching (ON/OFF) the incorporated PIN-diodes. The designed antenna is tested under the following applications; 3G, 4G AWS1 (1700-2100 MHz), Wireless-Area-Network (2.45 GHz and 5 GHz) and Worldwide Interoperability for Microwave Access (3.5 GHz). The designed antenna is fabricated as a C-shape monopole placed on the commercial FR-4 substrate. The antenna is simulated using the student version of the Computer Simulation Technology (CST-MWS). The three modes match the Reflection Coefficient (S11) < -10 dB and the efficiency >84%. The average gain ranged from 1.9 to 3 dBi. A prototype has been fabricated and measured. The comparison between the fabricated and simulated antenna results, such as S11, Efficiency, and gain, are illustrated. A good agreement between the results has been noticed which validates the design concepts.
