- Abstract
- The development of a small electrical antenna plays an important role in the rapidly growing mobile communication market This paper presents the design of a novel small and wideband planar inverted F-antenna that simultaneously covers the GSM900/GPS/DCS1800/DCS1900/IMP2000/WLAN/DMB service bands. A very wide impedance-bandwidth characteristic was achieved by optimizing both the distance between the feed line and short strip and the width of a short strip. The commercial electromagnetic software CST Microwave Studio is used to design the structure. The maximum gains at the frequencies of 915, 1850, 2025, and 2450 MHz were 1.79, 3.56, 3.65. and 1.67 dBi, respectively. The overall radiation pattern is suitable for mobile application.
