Abstract
An antenna is provided and includes a base antenna component, a loop antenna component, a first coupling by which the loop antenna component is pivotally attached to and selectively electrically communicative with the base antenna component, a whip antenna component, a second coupling by which the whip antenna component is pivotally attached to and selectively electrically communicative with the loop antenna component; and a transmission/reception (T/R) module. The T/R module is disposable in signal communication with at least one or more of the base, loop and whip antenna components.
Claims20
An antenna, comprising:
- a base antenna component;
- a loop antenna component;
- a first coupling by which the loop antenna component is pivotally attached to and selectively electrically communicative with the base antenna component;
- a whip antenna component;
- a second coupling by which the whip antenna component is pivotally attached to and selectively electrically communicative with the loop antenna component;
- and
- a transmission/reception (T/R) module which is disposable in signal communication with at least one or more of the base, loop and whip antenna components.
An antenna for attachment to a roof of a vehicle or fixed structure, the antenna comprising:
- a base antenna component affixable to the roof of the vehicle or fixed structure;
- a loop antenna component;
- a first coupling by which the loop antenna component is pivotally attached to and selectively electrically communicative with the base antenna component;
- a whip antenna component;
- a second coupling by which the whip antenna component is pivotally attached to and selectively electrically communicative with the loop antenna component;
- and
- a transmission/reception (T/R) module which is disposable in signal communication with at least one or more of the base, loop and whip antenna components.
An antenna array for attachment to an exterior surface of a vehicle or fixed structure, the antenna array comprising:
- a plurality of antennae that each comprise:
- a base antenna component affixable to the exterior surface of the vehicle or fixed structure;
- a loop antenna component;
- a first coupling by which the loop antenna component is pivotally attached to and selectively electrically communicative with the base antenna component;
- a whip antenna component;
- a second coupling by which the whip antenna component is pivotally attached to and selectively electrically communicative with the loop antenna component;
- a transmission/reception (T/R) module which is disposable in signal communication with at least one or more of the base, loop and whip antenna components;
- and
- a central control unit configured to control each of the first and second couplings and each of the T/R modules.
