Receiving Loop Antenna

Frequency sweep simulation of a receiving circular loop antenna.

The loop is modeled using conformal segments, which exactly follow the contour of the antenna geometry. This is far better than using straight segments as in NEC-based apps. AN-SOF is the only commercial simulation software that implements the Conformal Method of Moments (CMoM) >.

The antenna is in receiving mode, so it is excited by an external incoming plane wave. As the frequency increases, more sine function semi-cycles are obtained as a current distribution along the loop.

The radiation pattern shows the re-radiated power, and a plot of the RCS (Radar Cross Section) can be obtained in this case.
