Abstract

The design process of dual-band reconfigurable PIFA antenna is introduced and investigated. The design procedure is based on loading a lumped capacitor (or varactor) at one fixed location along a slot of the radiator. The changes in first and second resonances are significantly quite similar and almost cover the entire dual-band operation, with considerable frequency ratio tuning range. The proposed antenna was implemented and tested using chip capacitors varied between 1.5 to 4pF. The proposed tuning method has been demonstrated and measured over the range of 1.1 to 2.2GHz. Good agreement is obtained between the predicted and measured results over the whole frequency range.
