Abstract
The present invention provides a radome for an endfire antenna array that includes a honeycomb core, an inner skin attached to the honeycomb core, a first set of conductive slats disposed on the inner skin of the honeycomb core and a second set of conductive slats that are disposed within the honeycomb core. The two sets of conductive slats are capacitively-coupled to one another.
Claims13
A radome for an endfire antenna array comprising:
- a honeycomb core;
- an inner skin attached to the honeycomb core;
- a first plurality of conductive slats, disposed on the inner skin, arranged to provide a space between each slat;
- and
- a second plurality of conductive slats, disposed within the honeycomb core, arranged to provide a space between each slat and capacitively-coupled to the first plurality of conductive slats, wherein
- the first set of conductive slats prevents a substantial portion of an electromagnetic field from passing through the inner skin to the honeycomb core.
