Abstract
A new wide slot antenna with capacitively coupled CPW-feed and metalli c strips in the apertures is presented. The numerical analysis is base d on the Galerkin moment method in the spectral domain approach. A sim plified formula to calculate the input impedance is proposed. Theoreti cal and experimental results demonstrate the significant performance i mprovement of this modified structure. The influence of various design parameters is investigated. A 50% impedance bandwidth (SWR <2.0) and cross-polarisation levels below -20 dB are demonstrated.
