Study and simulation of wide band spiral microstrip antenna

摘要

The expanding use of wireless devices has prompted the need of larger bandwidths by these devices. This need is a result of larger bit-rates or the use of different standards using different frequency bands. In this work, Ultra Wide Band (UWB) 2-14GHz with its matching circuit is presented. The antenna responses, input impedance radiation pattern, currant distribution and VSWR at various frequencies are studied and compared to that of a commercial antennas. The viability of this antenna is tested using the simulator of CST-2010 tool.
