Abstract :
A novel technique to design and optimize a low profile wire antenna with high broadside gain is introduced. The desired antenna properties are achieved by loading an electrically long inverted-F antenna (IFA) with two optimal wire stubs along the body of the antenna. The best lengths and locations of the stubs as well as other antenna design parameters were selected by a new nature-inspired technique called Wind Driven Optimization (WDO). The results of this work demonstrate that an optimized stub-loaded inverted-F antenna (SLIFA) can provide not only lower profile than that of a conventional IFA but also an enhanced gain of 8.2 dB at broadside where the IFA has a null.
