Abstract

Various loop antenna fixture embodiments are disclosed. The fixture can be configured to removably attach with other fixtures, thus changing the overall dimensions of an antenna wrapped around the periphery of the fixture or fixtures. Advantageously, after the antenna is wrapped around the fixture(s) to form an assembly, the entire assembly can be removed and installed without the requirement of removing the antenna from the fixture(s).

Claims (47)

1 . A removable antenna fixture assembly for assembly of an antenna, the antenna fixture comprising:

an antenna fixture comprising:

a platform having a first end and a second end, the first and second end located generally opposite from one another;

a plurality of legs extending around the periphery of the platform, each of the plurality of legs having an antenna retainer portion; and

a first attachment element, the first attachment element located on the first end of the platform and having a first attachment configuration;

a wire wrapped around the plurality of legs and retained within the antenna retainer portion of the plurality of legs, the wrapped wire thereby forming a loop antenna; and

wherein the first attachment element of the antenna fixture is configured to mate with a second attachment element of a second antenna fixture, such that the antenna fixture is secured with the second antenna fixture.

2 . The removable antenna fixture assembly of claim 1 , wherein the platform comprises a threaded aperture passing at least partially through a thickness of the platform, the threaded aperture configured to receive and retain a screw for removable attachment of the platform to a surface.

3 . The removable antenna fixture assembly of claim 1 , wherein the platform comprises a score line configured to reduce the size of the removable fixture upon breaking.

4 . The removable antenna fixture assembly of claim 1 , wherein the removable antenna fixture comprises a plurality of pairs of legs, the legs in each pair being located on opposite side of a width of the platform from one another.

5 . The removable antenna fixture assembly of claim 4 , further comprising cross support structures connecting the pairs of legs.

6 . The removable antenna fixture assembly of claim 5 , further comprising axial support structures connecting adjacent cross support structures.

7 . The removable antenna fixture assembly of claim 1 , further comprising an energy source and transmitter attached to the platform.

8 . The removable antenna fixture assembly of claim 1 , further comprising the second antenna fixture.

9 . The removable antenna fixture assembly of claim 8 , wherein the antenna fixture and the second antenna fixture are identical.

10 . The removable antenna fixture assembly of claim 8 , further comprising a housing configured to slidably receive the fixtures.

11 . A method of manufacturing a loop antenna, the method comprising:

obtaining a fixture comprising:

a platform having a first end and a second end, the first and second ends being located generally opposite of one another; and

a plurality of retainers positioned around a periphery of the platform;

securing the fixture to a base;

wrapping a wire around the retainers of the fixture to form a loop, the loop and fixture together comprising an antenna assembly; and

removing the fixture from the base without removing the loop from the retainers of the fixture.

12 . The method of Clam 11 , wherein the fixture is a first fixture and further comprising providing a second fixture comprising:

a platform having a first end and a second end, the first and second ends being located generally opposite of one another; and

a plurality of retainers positioned around a periphery of the platform of the second fixture; and

attaching the second fixture to the first fixture.

13 . The method of Clam 12 , wherein the first and second fixtures are attached prior to securing the first fixture to the base.

14 . The method of Clam 12 , wherein the first fixture is secured to the base before attaching the first and second fixtures.

15 . The method of Clam 12 , further comprising wrapping a second wire around the second fixture.

16 . The method of Clam 12 , wherein wrapping the wire around the retainers comprising wrapping the wire around the retainers of both the first and second fixtures to form one loop encompassing both the first and second fixtures.

17 . The method of Clam 11 , further comprising installing the antenna assembly.

18 . The method of claim 17 , wherein the antenna assembly is configured to be installed in an overhead location.

19 . The method of claim 17 , further comprising connecting a transmitter located on the fixture, thereby facilitating the transmission of a signal from the transmitter via the antenna assembly to produce a signal zone on a floor region below the overhead location.

20 . An antenna fixture assembly comprising:

a first antenna fixture comprising:

a first platform having a first end and a second end, the first and second end located generally opposite from one another;

a first plurality of legs each comprising an antenna retainer portion; and

a first male connection element located on the first end of the first platform;

a first female connection element located on the second end of the first platform;

a second antenna fixture comprising:

a second platform having a first end and a second end, the first and second end located generally opposite from one another;

a second plurality of legs each comprising an antenna retainer portion;

a second male connection element located on the first end of the second platform;

a second female connection element located on the second end of the second platform;

wherein the first male connection element located on the first end of the first platform is matingly engaged with the second female connection element located on the second end of the second platform, thereby forming a linked assembly of the first and second antenna fixtures;

a conducting element wrapped around the periphery of the linked assembly of the first and second antenna fixtures, the conducting element being received in the antenna retainer portions the plurality of legs, the conducting element thereby forming a loop antenna that is secured with and supported by the first and second antenna fixtures.
