The use of frequency- and time-domain simulation algorithms for the prediction of free-running and injection-locked oscillators is discussed. The modelling of the passive radiating part of the antenna using the FDTD method is covered. Free-running oscillators are shown to be handled accurately and efficiently using the harmonic-balance algorithm, but injection-locked oscillators are a source of difficulty. The FDTD method, when compared to measurements, gives good results for the input impedance and mutual coupling of the passive array An overview of the modelling of an active microstrip patch array K Williams HC Reader DB Davidson doi:10.1109/COMSIG.1998.736985 Communications and Signal Processing, 1998.

The availability of an accurate model for the MRF136 MOSFET prompted the choice of 280 MHz as a convenient operating frequency. To facilitate time domain measurements, a second oscillator at 100 MHz was designed Nonlinear modelling of 1 watt active patch antenna HC Reader K Williams GA Hoile Antennas and Propagation, 1995., Ninth International Conference on (Conf.
