Mitigation of undesired electromagnetic radiation using passive elements

摘要

The present invention relates to an apparatus for mitigating undesired portions of electromagnetic radiation (EMR) associated with an antenna. The apparatus comprises a coupling element EM inductively coupled with the antenna, the coupling element being substantially co-polarized with the antenna. The apparatus further comprises one or more dissipating elements EM inductively coupled with the coupling element, each of the one or more dissipating elements being substantially differently polarized than the antenna, for example cross-polarized to the antenna. The coupling element may be a conductive element configured for predetermined EM inductive coupling with at least the antenna and the one or more dissipating elements. Each of the one or more dissipating elements may be a conductive element configured for predetermined EM inductive coupling with the coupling element. A method of manufacture is also provided.

1. An apparatus for mitigating undesired portions of electromagnetic radiation (EMR) associated with an antenna, the apparatus comprising:
a. a coupling element EM inductively coupled with the antenna, the coupling element being co-polarized with the antenna; and b. one or more dissipating elements EM inductively coupled with the coupling element, each of the one or more dissipating elements being differently polarized than the antenna;
wherein the coupling element is positioned at a fixed predetermined location proximate to the antenna between the antenna and the one or more dissipating elements such that EMR is reduced in a predetermined spatial region, and whereinthe coupling element and the one or more dissipating elements form a barrier between the antenna and the predetermined spatial region operable to limit EMR in the predetermined spatial region.
