Summary:
The Planar inverted-F antenna (PIFA) is currently in use as an embedded antenna in many radiotelephone handsets [1-8]. It is one of the most promising antenna types because it is small and has a low profile, making it suitable for mounting on portable equipments. The planar inverted-F antenna which is a type of microstrip antenna shows much promise in dealing with the shortfalls of the λ/4 monopole antenna in mobile communication applications [9]. The planar inverted-F antenna also has exhibited a reasonably high gain and possesses a bandwidth that is broad enough for mobile operation. [10-14]. However, PIFA have some drawbacks such as low efficiency, narrow bandwidth and inability to have a multi-band resonance. To enhance these shortcomings, especially narrow bandwidth, while meeting the miniaturization requirements of mobile devices, Fractal PIFA has been proposed, designed and presented in this work. Fractal PIFAs can be used as an internal antenna solution and to produce a wideband frequency range [15-18]. The proposed designs are able to provide coverage at all desired frequency bands i.e. GSM 1800/1900, Universal Mobile Telephone System (UMTS) and High Performance Wireless Local Area Network (HiperLAN) application. In order to obtain a good fundamental antenna design, the initial studies were carried out theoretically, using CST Microwave Studio software.
