An improved approach of locating failed elements in antenna arrays based on far field radiation pattern is proposed using genetic algorithms (GA). The locations of the failed elements were found based on the comparison between the results of the proposed model and the simulation from HFSS which was treated as the measured results of the array with failed elements. The success rate of the diagnosis...
A novel S band dual circularly polarized antenna array with 12 elements is presented for airborne satellite communication applications. The antenna array is composed of microstrip patches, 3dB hybrids and dividers. The simulated and measured results show that an impedance bandwidth of 14% (VSWR<2) is achieved. Radiation patterns with low cross polarization are achieved. The overall size of the...
