Abstract
Antennas suitable for deployment as part of a satellite, such as a low earth orbit (LEO) satellite. Some embodiments relate to antenna arrays for LEO satellites. An antenna, including a base; a first antenna patch body; and a second antenna patch body disposed substantially parallel to and spaced from the first antenna patch body; wherein the first and second antenna patch bodies are aligned along a central axis and coupled to the base; and wherein each of the first and second antenna patch bodies define surface corrugations.
Claims55
An antenna, comprising:
- a base;
- a first antenna patch body;
- and
- a second antenna patch body disposed substantially parallel to and spaced from the first antenna patch body,
- wherein the first and second antenna patch bodies are aligned along a central axis and coupled to the base,
- wherein each of the first and second antenna patch bodies define surface corrugations, and
- wherein the first and second antenna patch bodies are integrally formed as part of a unitary body.
An antenna patch body for a stacked patch antenna, the antenna body being integrally formed as a unitary body including a first antenna patch body, a second antenna patch body and a central portion joining the first antenna patch body to the second antenna patch body, wherein the first and second antenna patch bodies are substantially parallel with each other and spaced from each other.
A stacked patch antenna, comprising:
- a base;
- a first antenna patch body;
- a second antenna patch body disposed substantially parallel to and spaced from the first antenna patch body;
- and
- first, second, third and fourth straight walls projecting from the base on respective four sides of the first and second antenna patch bodies;
- wherein the first and second antenna patch bodies are aligned along a central axis and coupled to the base;
- wherein the first and second antenna patch bodies have a rectangular profile when viewed in a direction of the central axis;
- and
- wherein the first antenna patch body and the second antenna patch body are formed as part of a unitary body, wherein the unitary body includes a central portion joining the first antenna patch body to the second antenna patch body.
