Design and Characterization of Rectangular Stud Antenna

Abstract

This paper refers to the investigation and design of Stud (Cup link) Antenna. Studs are part of daily wears. Studs are available in various shapes and designs. To investigate the electromagnetic behavior of studs and its use as antenna, the analysis shows that studs can be used as antenna and it radiates electromagnetic energy from guided medium to free space. A rectangular stud antenna is considered and it parameters e.g. resonant frequency, directivity, radiation efficiency, half power beam width etc are calculated. The effects of dimensions e.g. length, width and thickness of conductor and substrate on resonant frequency, directivity and radiation efficiency are analyzed and it has been observed that these parameters can been modified by changing the dimensions of stud antenna.
