A novel, interlocking, snap-fit connection between an antenna aperture and a ground plane layer that contains coaxial connectors is described herein. The snap-fit design provides a simple and solderless transition from the connectors to elements of the antenna aperture. This design facilitates easy assembly and disassembly, allowing parts to be removed, reinstalled and/or reused.

Modular solderless connector integration for conformal phased arrays

Embodiments are directed configurations of antenna elements for conformal phased arrays (e.g., circular or cylindrical) to support either omnidirectional or directional high-gain beams. Antenna elements may be spaced about a circle or cylinder with a vertical and circumferential element spacing that is based on a wavelength of an operational frequency. Such a configuration of antenna elements enables easy scaling to different frequency bands and a straightforward extension from single-linear to dual-linear polarization. Furthermore, the antenna elements and their configurations enable conformal phased arrays to be formed as one integrated structure or with multiple modular structures.

Conformal phased arrays

An antenna system having a transmit assembly with a first set of antenna elements for transmitting signals. Each antenna element in this first set may be disposed from a respective adjacent antenna element by a predetermined azimuthal increment and by a predetermined altitudinal increment. The antenna system further includes a receive assembly having a second set of antenna elements for receiving signals. Each antenna element in this second set may be disposed from a respective adjacent antenna element by a predetermined azimuthal increment and by a predetermined altitudinal increment. The predetermined azimuthal and altitudinal increments of the first set may be substantially similar to the predetermined azimuthal and altitudinal increments, respectively, of the second set.
