Abstract :
This paper describes numerical modelling of a dual band multi-layered patch antenna operating at 35 GHz on an in-house semi-insulating GaAs substrate. The simulated and measured resonant frequencies at both the lower and upper resonant frequencies will be compared, so as to assess the suitability and accuracy of the different numerical techniques.
