Miniaturization of Ultra Wide Band (UWB) Antenna with Peripheral Slits Method at Frequencies of 500MHz-2.5GHz
AbstractAs the development of wireless communication technology is increasing, the high public demand for wireless telecommunications facilities is increasingly large. Current wireless technologies, such as TV, WiFi, and Cellular use one antenna with a single band frequency and size that is quite large. So in this final research, designing and making microstrip antennas for several applications using Ultra Wide Band (UWB) technology with smaller sizes in the frequency range of 500MHz - 2.5 GHz. A miniaturization technique that can reduce antenna patch dimensions by up to 43% is peripheral slits. Simulation and measurement results show there is a frequency shift after the antenna has been fabricated by 90 MHz on antennas without peripheral slits and 163 MHz on antennas with peripheral slits. Expected return loss at certain work frequencies already meets the expected parameters. The biggest return loss on the measurement results is at 771 MHz and 900 MHz frequencies reaching -26 dB and the resulting VSWR <2. Polaradiation from simulation and measurement results is omnidirectional. The application of peripheral slits technique proved to be able to reduce the dimensions of the antenna, so that an optimal final design was obtained with a enlcosure size of 144.8 Ã— 107 mm and patch size of 101 Ã— 86 mm.
