Abstract

A method, according to various aspects of the present invention, for improving wireless communications between two antennas includes, in any order, orienting the first antenna at a predetermined physical orientation such that the first antenna communicates using a predetermined polarization; orienting the second antenna at substantially the same physical orientation as the first antenna; and rotating the second antenna about 180 degrees such that the second antenna communicates using the same polarization as the first antenna.

Claims

1. A method for improving wireless communications between a first antenna and a second antenna, the method comprising:

orienting the first antenna at a predetermined physical orientation, wherein the first antenna communicates using a predetermined polarization;

orienting the second antenna at substantially the same physical orientation as the first antenna;

rotating the second antenna about 180 degrees, wherein the second antenna communicates using the same polarization as the first antenna.

2. The method of claim 1, wherein the first antenna and the second antenna each comprise a magnetic dipole antenna.

3. The method of claim 1, wherein the first antenna and the second antenna each comprise an inverted F antenna.

4. The method of claim 1, wherein the first antenna and the second antenna each comprise a microstrip patch antenna.

5. The method of claim 1, wherein the second antenna is rotated around at least one of the x-axis, the y-axis, and the z-axis.

6. The method of claim 1, wherein the first antenna and the second antenna each have substantially similar structure.

7. A system for communicating wirelessly using a radio signal of a predetermined polarization, the system comprising:

a first wireless cell having a first antenna;

wherein the first antenna has a first structure, a first physical orientation, and transmits and receives radio signals of a first polarization;

a second wireless cell having a second antenna;

wherein the second antenna has a second structure substantially similar to the first structure, a second physical orientation, and transmits and receives radio signals of the first polarization, wherein the second physical orientation is rotated 180 from the first orientation.

8. The method of claim 7, wherein the first antenna and the second antenna each comprise an inverted F antenna.
