Penta-Band Coupling Element Based Mobile Phone Antenna

In recent years, the mobile phone manufacturers have
increasingly focused on thinner and more
mechanically mixed products. These devices need to
be able to be operating with several different
mobile phone systems and in different frequency
bands. Based on the evolution in the wireless
industry, the handsets need also to be equipped with
other wireless functionality such as WLAN,
Bluetooth, and GPS. In order to work in multi-band
wireless systems, the design of the mobile phone antenna becomes a key issue.Based on the work by
Vilanen et al., a small, low profile and efficient
coupling element based antenna with penta-band
operations for the use in mobile telephones has been
studied in this book. The antenna was designed by a
High Frequency Structure Simulator, HFSS, built and
verified. Cases with different antenna dimensions
also have been investigated for the coupling
affection. The resulting antennas operate over two
wide bands from (824-1300) MHz and from (1710-2170)
MHz, covering five cellular bands
(GSM850/900/1800/PCS1900 and UMTS).
