Abstract
A cylindrically symmetric satellite antenna that provides directional and omnidirectional operating modes in a compact form factor. Feed points located at the top of the cylindrical structure provide increased platform isolation. Combining networks, disposed below or within the cylindrical structure, may be replaced with inexpensive baluns composed of coaxial line sections.
Claims11
An antenna apparatus comprising:
- four quadrant elements, each quadrant element comprising a conductive cylinder side section, a conductive cylinder top section, and a feed point;
- a first pair of the four quadrant elements positioned opposite to one another along a major axis;
- a second pair of the four quadrant elements elements positioned opposite to one another along the major axis;
- one or more capacitive elements interconnecting the conductive side section and the conductive top section of one or more of the quadrant elements;
- and
- a phasing module for selectively combining the feed points provided by respective quadrant elements.
