Abstract
An antenna system, comprising: an omni-directional antenna element; and a directional adapter having an electromagnetic reflector. The directional adapter detachably coupled to the omni-directional antenna element. The electromagnetic reflector being offset from the omni-directional antenna element. The directional adapter may be 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.
Claims12
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.
