Abstract
Multiband guiding structures for antennas and methods for using the same are described. In one embodiment, an antenna comprises: an antenna aperture with radio-frequency (RF) radiating antenna elements; and a center-fed, multi-band wave guiding structure coupled to the antenna aperture to receive a feed wave in two different frequency bands and propagate the feed wave to the RF radiating antenna elements of the antenna aperture.

An antenna comprising:
- an antenna aperture with radio-frequency (RF) radiating antenna elements;
- and
- a center-fed, multi-band wave guiding structure coupled to the antenna aperture to receive a feed wave in two different frequency bands and propagate the feed wave to the RF radiating antenna elements of the antenna aperture.
A multi-band antenna comprising:
- an antenna aperture with radio-frequency (RF) radiating antenna elements;
- and
- a guiding structure to propagate a feed wave in first and second bands at different frequencies, the guiding structure having first and second layers with first and second impedances, respectively, separated by a distance to create different spatial frequency responses for the first and second bands.
