NOVEL TRI-BAND WHIP ANTENNA FOR HANDHELD RADIO INCLUDING GPS BAND

摘要

Novel tri-band-whip antenna is investigated for 800/900 MHz bands digital and analog portable handheld radio application including GPS (1575 MHz) band. The tri-band characteristics are obtained by including two monopole elements with single feed point. Prototype of the proposed antenna is presented and its detail experimental analysis is described. Antenna parameters such as return loss, efficiency, and radiation gain patterns are measured and compared for various structures of the Whip antenna.
