Abstract

In this paper, we explain how to accurately simulate, using the method of moments (MoM) and the physical optics (PO) approximation, antennas with a coaxial probe feed. Special attention is given to properly modeling with MoM the connection between the antenna and the coaxial cable. Results were validated by comparison with measurements covering different electrical sizes of a grounded monopole antenna for airplanesatellite communication at the IEEE C-band. Good agreement, in radiation pattern and gain, is observed between MoM and PO. Equivalent circuit parameters are obtained through simulation, which allows to predict the communication system performance.
