ScholarBank@NUS Repository. https://doi.org/10.1109/TAP.2003.818007 | Abstract: | In this paper, we present an electrically small antenna for use with high efficiency power amplifiers for wireless applications. A planar inverted-F antenna design is described that can be optimized as a class-F termination for use as a load at the output of a field effect transistor (FET) for optimum output power and efficiency. An active planar inverted-F antenna is shown to have greater than 50% power-added efficiency at several frequencies between 1-2 GHz by scaling the radiating element. These antennas are also shown to provide a copolarized field component in the azimuth plane and a cross-polarized field component in the elevation plane. | Source Title: | IEEE Transactions on Antennas and Propagation | URI: | http://scholarbank.nus.edu.sg/handle/10635/54879 | ISSN: | 0018926X | DOI: | 10.1109/TAP.2003.818007 |
