多频天线设计A Multiband Antenna for Mobile Phones
by Hiroyuki Tamaoka * , Hiroki Hamada * and Takahiro Ueno *

Antennas for mobile phone handsets are generally required to have such characteristics as compactness, complete built-in mountability, multiband operation and environmental isolation, as well as broad bandwidth and high efficiency. However, conventional technologies represented by planar inverted-F antenna (PIFA) are reaching their limit of improvement to meet the market requirements. In an effort to better such a situation, we have developed a novel model of antenna --for single band and multiband operation-best suited for mobile phone handsets through full utilization of electromagnetic simulation techniques. The antenna developed here features the use of a specific radiator pattern and a r
