Parabolic Dish near Wire Crane

This application note examines the influence of the crane to the radiation pattern of the antenna with parabolic dish. Using Wire entities as building elements enables the code to very efficiently model wire-like structures (such is the crane presented in this document), with many times less unknowns than equivalent all-plate models.

Two models are investigated: a solitary dish antenna above perfectly conducting ground plane and the dish antenna in vicinity of a crane above perfectly conducting ground plane. The parabolic reflector diameter is 3.57 m and it is fed by a dual-mode horn with a choke. The system is designed for the operating frequency of 2.8 GHz. The crane is 30 m high and its arms are 28 m long, in total.

The radiation pattern with and without the crane is compared. The simulations were carried out on regular desktop PC (or any laptop) lasting just a couple of seconds for both models.
