Effect of the chassis length on the bandwidth, SAR, and efficiency of internal mobile phone antennas

The effect of the chassis length on the characteristics of the combination of an internal mobile phone antenna and a phone chassis were studied with simulations at 900 MHz and 1800 MHz. The results show that a local increase of SARs and a local decrease of radiation efficiency occur when the bandwid...

Zusammenfassung:The effect of the chassis length on the characteristics of the combination of an internal mobile phone antenna and a phone chassis were studied with simulations at 900 MHz and 1800 MHz. The results show that a local increase of SARs and a local decrease of radiation efficiency occur when the bandwidth reaches its maximum. This happens when the resonant frequency of the chassis equals that of the antenna. © 2003 Wiley Periodicals, Inc.
