Antenna solution for mm-wave systems

An antenna system configured to provide a fixed radiation pattern, the antenna system comprising:

• a first antenna element configured to provide a peak gain in a broadside direction;
• and
• a plurality of additional antenna elements, each additional antenna element oriented and directional to have a peak gain in an off-broadside direction where a gain of the first antenna element falls off from the peak gain in the broadside direction;
• and
• a beamformer configured to feed the first antenna element and the plurality of additional antenna elements to produce a fixed beam that has a donut pattern surrounding the broadside direction and has at least one peak gain in an off-broadside direction.

An antenna system for providing a fixed radiation pattern that is rotationally symmetric about a broadside direction and having a gain over an angular sector of greater than 120 degrees that includes the broadside direction, the antenna system comprising:

• a broadside antenna element configured to provide a broadside radiation pattern with a higher gain in the broadside direction than a gain of the broadside antenna element at 120 degrees;
• a beamformer having beam shaping capabilities and configured to feed the broadside element and an array of additional antenna elements to provide a fixed rotationally symmetric off-broadside radiation pattern to extend coverage of the antenna system to the angular sector of greater than 120 degrees;
• and
• the array of additional antenna elements disposed around the broadside antenna element, each antenna element of the array of additional antenna elements having a directional radiation pattern pointed toward an off-broadside direction to produce a composite beam that has a donut pattern.
