Electronically steerable antenna array

A system, comprising:

• a steerable and switchable antenna array configured to produce a first beam with a first coverage range and a second beam with a second coverage range;
• a processor;
• and
• a memory storing instructions that, when executed by the processor, enable the steerable and switchable antenna array to:
• switch signal inputs to narrow-beam antenna arrays included in the steerable and switchable antenna array;
• steer the first beam to one of a first positive offset, a first negative offset, and a first neutral position;
• steer the second beam to one of a second positive offset, a second negative offset, and a second neutral position;
• and
• transmit signals received from the signal inputs via the first beam and the second beam.

A method, comprising:

• forming, by a first antenna segment, a first beam with a first coverage range, wherein forming the first beam includes:
• steering the first beam to one of a first neutral position, a first positive offset, or a first negative offset by phase shifting signals for transmission according to the first beam across a first antenna array;
• forming, by a second antenna segment, a second beam with a second coverage range, wherein forming the second beam includes:
• steering the second beam to one of a second neutral position, a second positive offset, or a second negative offset by phase shifting signals for transmission according to the second beam across a second antenna array;
• wherein the first coverage range and the second coverage range form a boresight pattern when the first beam is steered to the first positive offset and the second beam is steered to the second negative offset;
• and
• wherein the first coverage range and the second coverage range form an expanded linear pattern with spatial isolation between the first coverage range and the second coverage range when the first beam is steered to the first negative offset and the second beam is steered to the second positive offset.
