Abstract
ABSTRACTRecent surge in the development of wireless communication has increased the need of the antennas that can operate at more than one frequency band. To meet the requirements, reconfigurable antennas are used. This paper presents design and analysis of a low profile, planar and, frequency reconfigurable E-shape patch antenna, using a 1.6 mm thicker FR-4 substrate. The antenna operates in two single-band and two dual-band modes, depending on the status of the two switches. The proposed antenna works efficiently (>90%) with an adequate gain (>2 dBi) and bandwidth (430 MHz–1 GHz) in the desired frequency bands {WiFi (2.45 GHz), WiMAX (3.59 GHz), WLAN (5.2 GHz), Military/NATO (4.5 GHz), C-Band (6.22 and 6.27 GHz)}. The antenna is optimally matched (VSWR < 1.45) in all these six frequency bands. The proposed antenna is compact in size (40 × 35 mm2) and can be used in portable electronic devices to support multiple wireless services. The antenna is analysed in computer simulation technology, microwave studio (CST MWS). The prototype is fabricated and measurements are conducted to validate the simulations.
