Abstract

A phased array antenna panel includes a plurality of antennas and a master chip. The antennas are arranged in a plurality of antenna rows. At least one antenna row in the plurality of antenna rows is configured to be slanted in a desired angle based on signals received from the master chip. Additionally, the phased array antenna panel can include a plurality of row-shaped lenses. At least one row-shaped lens has a corresponding antenna row, and is configured to increase a gain of the corresponding antenna row. The row-shaped lens can increase a total gain of the phased array antenna panel. The row-shaped lens is configured to be slanted in a desired angle based on signals received from the master chip.

Claims

1. A phased array antenna panel comprising:

a plurality of antennas arranged in a plurality of antenna rows;

a plurality of row-shaped lenses;

at least one of said plurality of row-shaped lenses having a corresponding antenna row in said plurality of antenna rows;

said at least one of said plurality of row-shaped lenses providing a gain to said corresponding antenna row so as to increase a total gain of said phased array antenna panel;

said at least one of said plurality of row-shaped lenses and said corresponding antenna row being configured to be slanted in a desired angle based on signals received from a master chip in said phased array antenna panel, thereby changing a direction of an RF beam formed by said phased array antenna panel.

2. The phased array antenna panel of claim 1, further comprising:

a plurality of radio frequency (RF) front end chips;

wherein said master chip provides phase shift signals for said plurality of antennas through said plurality of RF front end chips.

3. The phased array antenna panel of claim 1, further comprising:

a plurality of radio frequency (RF) front end chips;

wherein said master chip provides amplitude control signals for said plurality of antennas through said plurality of RF front end chips.

4. The phased array antenna panel of claim 1, wherein said plurality of antennas and said master chip are integrated in a single printed circuit board (PCB).

5. The phased array antenna panel of claim 1, wherein said least one of said plurality of row-shaped lenses is configured to be slanted while being maintained in parallel with said corresponding antenna row in said plurality of antenna rows.

6. The phased array antenna panel of claim 1, wherein said corresponding antenna row in said plurality of antenna rows is configured to be slanted by a piezo-actuator.

7. The phased array antenna panel of claim 1, wherein said corresponding antenna row in said plurality of antenna rows is configured to be slanted by an electrostatic actuator.

8. The phased array antenna panel of claim 1, wherein said corresponding antenna row in said plurality of antenna rows is configured to be slanted by a microelectromechanical systems (MEMS) actuator.

9. The phased array antenna panel of claim 1, wherein said phased array antenna panel is a receiver, and said direction of said RF beam is substantially perpendicular to said corresponding antenna row.

10. The phased array antenna panel of claim 1, wherein said phased array antenna panel is a transmitter, and said direction of said RF beam is substantially perpendicular to said corresponding antenna row.
