Abstract

This paper proposes a new type of a dual-band internal antenna for GPS/PCS handsets. The antenna has three monopoles in different lengths, and this structure is referred as a 3-fingers type antenna in this paper. The antenna with low-profile structure is designed to use internal space of handset maximally. The fabrication and the measurement are accomplished by attaching the 3-finger type antenna to the inside of a commercial handset. We obtain gain of 1.97 dBi$\~$0.66 dBi in the GPS band, and -0.92 dBi$\~$1.02 dBi in the PCS band and almost omni-directional patterns at all bands.
