Abstract

See full text

An electromagnetic bandgap device is mountable on a RF disturbing structure of an antenna to minimize signal field disturbance imparted thereby. The RF disturbing structure is oriented in a direction substantially parallel to a path of travel of an antenna signal and located within a field covered by the signal transmitted by a feed. The bandgap device comprises a plurality of RF perturbing elements connected to the RF disturbing structure and spaced apart from one another in the direction substantially parallel to the signal path. The perturbing elements are positioned, configured and sized to direct a disturbed portion of the signal away therefrom to reduce field disturbance generated by the disturbed signal portion interacting with an undisturbed portion of the antenna signal.
