A Three-Element Antenna Array for Light Weight Wireless Mobile Handsets
Antenna beam-forming is largely confined to stationary base stations that combine electromagnetic signals from array antenna elements to form a desired output. The array antenna suppresses signals in certain directions while amplifying signals from certain directions. One major reason that multiple antenna elements are less advantageous on mobile handsets is the additional power and weight needed for the signal processing.
Description of Technology
This technology enables a three antenna wireless mobile station. It can increase power reception in the direction of the desired signal while simultaneously minimizing signals in the direction of interference. Analytically derived solutions of radiated electromagnetic fields are used to achieve the design goals of maximizing and minimizing reception in different directions simultaneously. By simultaneously maximizing the beam in the desired direction and nulling the unwanted signals, one can achieve faster processing by the electromagnetic signal processor, less memory usage by the mobile device, and better signal clarity with less noise.
- Light weight mobile devices – The model based signal processor created in this technology utilizes less memory within the mobile device for picking up signals and ultimately less hardware.
- More accurate signal processing- Robust analytic solutions to find the directions of enhanced and suppressed signal allows for more accurate signal processing.
- Faster signal processing – While the state of the art model based signal processing systems crunches numbers that waste’s valuable time, this technology uses a processing system that process signals at a faster rate.
- Wireless mobile communication - While using less memory and ultimately less hardware in the mobile devices, this technology could enable a less expensive and/or longer lasting battery source for mobile devices.
