Wideband radio frequency directional antenna adaptor

1 . An antenna adapter, comprising:

a mechanical coupler coupled to support members and attachable to an antenna; and

an electromagnetic reflector coupled to the support members so as to be offset from the mechanical coupler in a first direction;

wherein the antenna adapter is configured to be coupled to the antenna to convert a radiation pattern from an omni-directional antenna radiation pattern to a directional antenna radiation pattern, and configured to be decoupled from the antenna to convert the radiation pattern back into the omni-directional antenna radiation pattern;

wherein the support members extend between the mechanical coupler and respective sides of the electromagnetic reflector and have lengths that are variable; and

wherein the electromagnetic reflector has a variable size that is increased by applying a force thereto as the lengths of the support members expand.

2 . The antenna adapter according to claim 1 , wherein the antenna adapter is further configured to convert the antenna into one or more of a yagi antenna, a parabolic antenna, a reflector antenna, a horn antenna, a corner reflector antenna, and a cavity antenna.

3 . The antenna adapter according to claim 1 , wherein the antenna adapter comprises a reflector that is offset a first distance in a first direction from the antenna when the antenna adapter is coupled thereto.

4 . The antenna adapter according to claim 3 , wherein the electromagnetic reflector is configured to be interchanged with another electromagnetic reflector having a different size and/or shape.

5 . The antenna adapter according to claim 3 , wherein the antenna adapter further comprises at least one director that is offset a second distance in an opposing second direction from the antenna when the antenna adapter is coupled thereto.

6 . The antenna adapter according to claim 5 , wherein the at least one director is configured to be removed from the antenna adapter to further convert the antenna from the directional antenna of a yagi type to another directional antenna of a reflector type.

7 . The antenna adapter according to claim 5 , wherein the at least one director is configured to be interchanged with another director having a different size.

8 . The antenna adapter according to claim 5 , wherein the antenna adapter further comprises another director that is offset a third distance in the opposing second direction from the antenna when the antenna adapter is coupled thereto, the third distance greater than the second distance.

9 . The antenna adapter according to claim 1 , wherein:

the antenna adapter comprises at least one director coupled to the support member so as to be offset from the mechanical coupler in the opposing second direction; and

the directional antenna radiation pattern is changeable by adjusting a distance between the antenna and the electromagnetic reflector of the antenna adapter and/or adjusting a distance between the antenna and the at least one director of the antenna adapter.

10 . The antenna adapter according to claim 1 , wherein a curvature or an angle of the electromagnetic reflector is variable.

11 . The antenna adapter according to claim 10 , wherein the electromagnetic reflector is made of a conductive material that can be bent or deformed to change the curvature or the angle.

12 . The antenna adapter according to claim 1 , wherein an outer most edge of the mechanical coupler is aligned with a center of the antenna adapter and the mechanical coupler extends from the center of the antenna adapter in the first direction towards the electromagnetic reflector.
