Planar Inverted F-Antenna (PIFA) The Planar Inverted-F antenna (PIFA) is increasingly used in the mobile phone market. The antenna is resonant at a quarter-wavelength (thus reducing the required space needed on the phone), and also typically has good SAR properties. This antenna resembles an inverted F, which explains the PIFA name.

Antenna selection guidelines By Placido De Vita Introduction The antenna is a very important component of communication systems. By definition, an antenna is a device used to transform an RF signal, travelling on a conductor, into an electromagnetic wave in free space (transmit mode), and to transform an RF Limitations And Advantages Of A Directional Antenna Fixed beam antenna has fixed gain profile with a primary lobe pointing in a single direction. We only can steering the beam by changing the orientation of the antenna physically , which permit relatively slow changes at best. This kind of antenna does provide high gain for their cost and are widely deployed in practice.
