Abstract

A novel and compact antenna for ISM 433MHz frequency band is presented. The wireless system working at ISM band consists of a metal meander micro-strip line, a transceiver circuit with a metal shield and a rectangular plane ground serving as both the battery´s ground and a part of the radiator. To make the antenna work in such a small area, and meanwhile, maintain enough bandwidth, the metal shield of the transceiver circuit in this work is connected to the metal meander line, which is different from the traditional design. The antenna is designed to operate at ISM 433MHz band on a small PCB (76mm*55mm) and has a bandwidth of 3MHz.
