Planar Antenna's Performance Belies Size

Often, designers of compact wireless products find their antenna options and performance limited by size, cost and cosmetic considerations. The Splatch planar antenna provides an alternative. The device uses a proprietary grounded-line technique to deliver high performance from a tiny surface-mount element.Unlike many compact antennas, the Splatch antenna is said to be highly immune to proximity effects, making it suitable for use in hand-held applications such as remote controls, pagers and alert devices. Its stable design enables even engineers without prior RF experience to obtain excellent performance. The antenna measures 1.1" long x 0.5" wide x 0.062" tall. It exhibits a 50 ohm characteristic impedance and low VSWR. Standard and custom frequencies range from 300 MHz to 900 MHz.
