Multiband Flat-Plate Inverted-F Antenna for Wi-Fi/WiMAX Operation

A printed multiband flat-plate inverted-F antenna (IFA) is presented. The antenna is complexly structured and can operate as an internal laptop antenna over multiple Wi-Fi and WiMAX frequency bands. The antenna was studied by means of numerical simulations. The predicted achievable -10 dB return loss bandwidth of the antenna is confirmed and demonstrated by experimental measurements.
