Abstract—With the increasing improvement of computer and computational method, many electromagnetic simulators solving antenna problems are widely used. In this paper, the electromagnetic simulator CST is applied to the analysis and design of a planar circular ring antenna with stub for ultra wideband applications with band notch performance. The antenna parameters are adjusted to achieve return loss of 10 dB over the desired frequency range (3.1 – 10.6 GHz) except the notch frequency band. The simulated result for return loss is in good agreement with the measured result.
Index Terms—Band notched antenna, Circular ring monopole antenna, electromagnetic simulator.
