Mobile phones have become a popular communication equipment in our daily life. Increasing of signal receiving capability of a mobile-phone ordinarily is obtained by the antenna on the top surface of the phone. A mobile phone is not connected with a conductor normally, and is powered by batteries. Thereby it must transmit and receive signals by aiding of an antenna. An antenna, one of essential components of the cellular phone, is a crucial factor for determining speech quality. Various types of antennas are known for use with cellular telephones. Generally, antennas either have a fixed length or are retractable from an extended position. Retractable antennas enable the user to retract most of the length of the antenna into the device housing, thereby improving device portability. Antennas for cellular transceivers comprise a helical coil antenna mounted atop a rod antenna. Both the rod antenna and coil antenna are adapted for transmitting and receiving electrical signals. Plannar inverted F-antennas (PIFA) are antennas that include a metallic plate or layer acting as ground plane for the antenna, a resonator plate or layer acting as radiating element, and a feeding point supplying the signal to the antenna. Cell phone antenna using only a single frequency (900 MHZ) can suit two different frequencies (900 MHZ and 1800 MHZ) when it uses a frequency matching structure.
