Abstract :
It is important to have analysis and design methods which are accurate and efficient as well as designs of active integrated antennas that satisfy the most important specifications in the area of wireless communications. We introduce an active integrated antenna design and analysis approach based on a hybrid combination of full wave/nonlinear circuit solvers. A prototype antenna working at 2.01 GHz is designed and fabricated using a low cost medium power silicon bipolar transistor. The radiation patterns are calculated with two different FDTD models of the antenna and compared with measurements. Numerical and experimental results for the radiation patterns are found to be in good agreement and the cross-polarizations in the main beam region are 30 dB and 25 dB down in the H- and E-planes, respectively.
