Design of a Coupling Element Based Penta-band Mobile Phone Antenna

• Based on the work by Vilanen et al., a small, low profile and efficientcoupling element based antenna with penta-band operations for the use inmobile telephones has been studied. The antenna was designed using the HighFrequency Structure Simulator, HFSS, from Ansoft. Two prototypes withdifferent antenna profile heights have been built, verified and tested. Thebandwidth of the antenna is extended compared to the original design. Alumped element based network is used to optimize the matching. Theresulting antenna operates (|S11|≤-5 dB) from 824 to 1300MHz and from1710 to 2170MHz, covering in total five cellular bands with an efficiencybetter than -3dB and a total volume of less than 4cm3.
