Meandered planar inverted-F antenna for PCS mobile phone

This paper describes an internal antenna design for a PCS mobile phone. The structure of the antenna was designed as a meandered planar inverted-F antenna (PIFA) in order to obtain a high gain. The radiation level in the vicinity of the human head was lowered to obtain a low SAR (specific absorption rate). However, the antenna was designed to achieve the highest degree of forward radiation level. The antenna designed in this study was installed at a commercial mobile phone, where it was applied to the actual environment.
