Abstract

Abstract It is possible to construct a multi-tuned antenna to place a small metallic object near by the original antenna which has a fundamental resonant frequency. The size of the metallic object parasitic element) is much smaller than the original antenna. The intrinsic resonant frequency of the parasitic element is higher than the original antenna. The antenna with the parasitic element has two resonant frequencies. One is the original resonant frequency and other is the parasitic resonant frequency. This type of antenna can be operated at 2.4 GHz and 5.2 GHz ISM bands wireless LAN application and also suitable for a software wireless equipment by single antenna system without any switching device.
