Abstract :
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. The antenna was designed using the High Frequency Structure Simulator, HFSS, from Ansoft. Two prototypes with different antenna profile heights have been built, verified and tested. The bandwidth of the antenna is extended compared to the original design. A lumped element based network is used to optimize the matching. The resulting antenna operates (|S11|<-5 dB) from 824 to 1300 MHz and from 1710 to 2170 MHz, covering in total five cellular bands with an efficiency better than -3 dB and a total volume of less than 4 cm3.
