Abstract
A satellite assembly 10 is provided, including an RF radiating element 12 including a plurality of RF choke elements 18, each of said plurality of RF choke elements 18 being defined by an RF dimensional set 20 including an RF depth 22 and an RF width 24. The satellite assembly 10 further includes a null aperture field zone 26 created by the plurality of RF choke elements 18, the null aperture field zone 26 created by tuning each of the RF dimensional sets 20. At least one field sensitive component 14 is positioned within said null aperture field zone 26.
Claims22
A satellite assembly comprising:
- an RF radiating element including a plurality of RF choke elements, each of said plurality of RF choke elements being defined by an RF dimensional set including an RF depth and an RF width;
- a null aperture field zone created by said plurality of RF choke elements;
- said null aperture field zone created by tuning each of said RF dimensional sets;
- and
- at least one field sensitive component positioned within said null aperture field zone.
A satellite assembly comprising:
- an aperture antenna including a number N of RF choke elements, each of said number N of RF choke elements being defined by an RF dimensional set including an RF depth and an RF width;
- a null aperture field zone created by said number N of RF choke elements;
- said null aperture field zone adjusted by the quantity of said number N of RF choke elements and by tuning each of said RF dimensional sets;
- and
- at least one field sensitive component positioned within said null aperture field zone.
A method of reducing the effects an RF radiating element, including a plurality of RF choke elements, on a field sensitive component comprising:
- tuning the RF depth of each of said plurality of RF choke elements such that the plurality of RF choke elements create a null aperture field zone that coincides with the placement of a field sensitive component.
