TOKYO, February 6, 2018 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today its development of the REESA (Rotational Element Electronically Scanned Array) antenna, a small, low-cost array antenna that achieves high-precision beam scanning by electronically rotating antenna elements individually. The REESA antenna is suitable for airport radar systems, mobile satellite communication systems and possible new applications such as microwave-based industrial heating and mounting on drones for long-distance data transmission. Commercialization of the product is targeted at 2020.

Key Features

1)
Rotates antenna elements individually for precise phasing and beam scanning
- Controls phase by rotating circularly polarized antenna elements individually by motors
- Realizes high-precision beam scanning by controlling phase in approx. two-degree increments
- Smaller and les expensive than conventional mechanically driven parabola antennas and active electronically scanned arrays (AESAs).
2)
Achieves high efficiency and low power consumption
- Uses a hollow waveguide for the antenna feed to achieve high efficiency of 85 percent in 12 GHz band
