This article describes the design, fabrication, and measurement of an internal FM radio ferrite sheet flexible antenna using an arrow-shaped patch to enhance passive gain performance for mobile handsets. To obtain sufficient passive gain performance >=-20 dBi, an arrow-shaped patch is inserted in the antenna radiator and monopole type wire is used. The measured result of the fabricated antenna provides passive gain performance (15.6-13.5 dBi) from 86 to 108 MHz with the frequency modulation (FM) bandwidth from 83.20 to 123.72 MHz (<= voltage standing wave ratio (VSWR) 6: 1). Also, a good radiation pattern is achieved within the FM bandwidth (86-108 MHz) range. VC 2011 Wiley Periodicals, Inc.
