摘要：

This letter presents the performance of a T-shaped monopole antenna loaded with an annular dielectric resonator as an ultrawideband transmitting/receiving antenna. By adjusting the length of the monopole and load arm, a 10-dB bandwidth of 110% is achieved while maintaining monopole-like radiation pattern. The antenna factor of the same antenna, while used as electromagnetic interference (EMI) sensor is also presented for the desired and cross-polarized component of incident electric field. The results for antenna factor show an ultrawide bandwidth with the cross-polarization isolation better than 86 dB/m for the T-monopole/DRA as EMI sensor. The simulated result for return loss is verified with the measured data from a prototype antenna.
