Abstract :
The three dimensional finite difference time domain (FDTD) algorithm is used to analyze broadband “finite sized” phased arrays antennas that are suitable for wireless communications applications. The antennas analyzed are a coaxially-fed and capacitively coupled stacked microstrip. A phase shift in the time domain is implemented to model the effects of scanning angle. A rigorous feed model, suitable for FDTD analysis with the perfectly matched layer (PML) is used. The mutual coupling and active impedance are calculated and compared to measurements
