Compact planar antenna for short range and low power transceivers

This paper presents design, simulation, fabrication and testing of compact planar antenna for short range and low power applications. It was designed to the center frequency of 867.5 MHz with the bandwidth of 5 MHz unlicensed ISM band. The planar epsiv_r = 4.3 glass epoxy was selected and designed for ISM band specifications. It was simulated using ADS 2002C which is a widely used RF and microwave component and system design tool. The fabricated antenna was tested using J6800 which is Agilent´s vector network analyzer used to measure up to 20 GHz. The results of simulated and tested antenna parameters were compared and concluded the performance of given antenna.
