Journal ArticleDOI
Resonator-based analysis of the combination of mobile handset antenna and chassis
TL;DR: In this paper, the performance of the mobile phone handset antenna-chassis combination is analyzed based on an approximate decomposition of the waves on the structure into two resonant wavemodes: the antenna-element wavemode and the chassis wavemode.
Journal ArticleDOI
Angular power distribution and mean effective gain of mobile antenna in different propagation environments
TL;DR: The results show that in non-line-of-sight situations, the power distribution in elevation has a shape of a double-sided exponential function, with different slopes on the negative and positive sides of the peak.
Journal ArticleDOI
Coupling element based mobile terminal antenna structures
TL;DR: The study of internal low-volume antenna structures for mobile terminals shows that the studied antenna concept is a very promising alternative for traditional antenna technologies.
Journal ArticleDOI
Bandwidth, SAR, and efficiency of internal mobile phone antennas
TL;DR: In this paper, the effects of several phone chassis-related parameters-length, width, thickness, and distance between the head and phone-on the bandwidth, efficiency, and specific absorption rate (SAR) characteristics of internal mobile phone antennas are investigated.

Tunable antenna for wireless communication terminals
TL;DR: In this article, a radio antenna (10) comprising a tuning component, such as a transmission line (40), coupled to the radiating element (20) for providing a frequency shift from the resonant frequency, and an adjustment mechanism (60) for adjusting the frequency shift by effectively changing the length of the transmission line.
