Sphere Phased Array Antenna

Introduction

A 3D sphere phased array antenna that provides half sphere coverage that simultaneously transmits or receives signals in four beams rather than a standard directional phased array antenna that transmits and receives in a specific direction only.

A printed device can have any combination of transmitters and a receive, and each pyramid structure radiation source can have a different frequency direction and intensity and can be either a transmitter or a receiver. Learn more about the possibilites of Nano Dimension AME.

The 3D structure integrates printed coil on each beam direction (4 coil for each source) and a structure that allows the beams to receive/transmit signals in four axes simultaneously.

Main Advantages

1. Simultaneous wide scanning area offering half spheric coverage in comparison to a single direction of coverage in a standard phased array antenna.
2. Miniaturization, saving real-estate, utilizing printed coils rather than external MEMs and an efficient 3D structure for a perfect impedance alignment between a coil to beam transmitter/receiver.
3. Custom design of the antenna array that enables optimized fit to the structure.
4. Reduced loss of parasitic capacitance due to the low 2.8 epsilon number rather than 3.8-4.5 in a FR4 structure.
5. Simple additive manufacturing process without assembly and soldering shorten the development, testing and optimization cycles.
6. One step production solution shorter production time and lower overall cost.
