Electromagnetic detection system
First Claim
1. An electromagnetic detection system comprising a transmitter-receiver apparatus and at least one antenna element, said transmitter-receiver apparatus being coupled to said at least one antenna element to form an electromagnetic interrogation field in an interrogation zone, structural confining means for defining the range and area of said interrogation zone and for physically confining mobile entities to be interrogated in said interrogation zone, and a plurality of responders attached to each of said mobile entities and capable of generating a detectable signal under the influence of said interrogation field, said at least one antenna element being formed as an integral part of said structural confining means, said structural confining means comprising an automatic feeding station for animals comprising a food dispenser, two side railings, and two bows for reinforcing said side railings and extending over said railings and said interrogation zone, said at least one antenna element being integrally formed with at least one of said bows.

Abstract
An electromagnetic detection system comprises a transmitter-receiver apparatus coupled to at least one antenna element to form an electromagnetic interrogation field in an interrogation zone defined at least in part by physical means. A plurality of responders is capable of generating a detectable signal under the influence of an interrogation field. According to the invention, at least one antenna element is a suitably formed structural element forming part of the physical means.
