Abstract

A connector for an RF antenna for coupling the RF antenna to a device is formed from a base. A collar is provided for receiving and coupling to an RF antenna. A coupling structure extends from the base and engages the device to facilitate coupling of the antenna to the device. An antenna system is also formed from an RF antenna and a device to which the RF antenna couples and for which the RF antenna is used. The antenna system further includes a connector formed from a base, a collar for receiving and coupling to the RF antenna and a coupling structure that extends from the base and engages the device to facilitate coupling of the antenna to the device.

Claims

1. An antenna system comprising:

an RF antenna having a feed conductor or feed pin extending from a proximal end of the RF antenna;

a device to which the RF antenna couples and for which the RF antenna is used;

and a connector that comprises;

a base having an opening for allowing passage of said feed conductor or feed pin therethrough;

a collar that extends from the base for receiving and coupling to the RF antenna; and

a coupling structure that extends from the base and engages the device separately and apart from said feed conductor of feed pin to facilitate coupling of the antenna to the device; and

wherein

the base and collar are sized and configured to closely receive the proximal end of the RF antenna.

2. The antenna system of claim 1, wherein:

the coupling structure is formed from at least one of (A), (B) and (C), wherein (A) is spaced apart mounting members that project from the base and are configured to engage and receive at least a portion the device between the spaced apart mounting members;

B) is connecting projections that are configured for at least one of being received within corresponding holes formed in the device and engaging pads of the device; and

(C) is a threaded connector.

3. The antenna system of claim 1, wherein:

the opening is centrally located within the base.

4. The antenna system of claim 3, wherein:

the coupling structure is formed from a pair of spaced apart mounting members that project from the base and are configured to engage and receive at least a portion the device between the spaced apart mounting members, the inward faces of the spaced apart mounting members being located to one side of a centerline of the connector that passes through the center of the central opening.

5. The antenna system of claim 1, wherein:

at least a portion of at least one of the base and collar are formed from electrically conductive materials that are configured for making electrical contact with the RF antenna; and

at least a portion of the coupling structure is formed from an electrically conductive material and is in electrical contact with said at least a portion of said at least one of the base and collar.

6. The antenna system of claim 1, wherein:

the connector is configured as one of (A) and (B), wherein is an end-mount connector wherein the connector is configured to couple to the end of a circuit board of the device so that a longitudinal axis of the RF antenna is oriented parallel to a plane of the circuit board, and (B) is a surface-mountable connector wherein the connector is configured to mount to a circuit board of the device so that the longitudinal axis of the RF antenna is oriented perpendicular to the circuit board.

7. The antenna system of claim 1, wherein:

the connector further comprises a DC blocking device to facilitate blocking of DC signals.

8. The antenna system of claim 1, wherein:

the connector is provided with at least one of a connector pin that is separate from said feed conductor or feed pin of the RF antenna and a ground plane.

9. The antenna system of claim 1, wherein:

the connector is configured as at least one of an SMA, SSMA, TNC, MCX MMCX, and SMB connector.

10. A connector for an RF antenna for coupling the RF antenna to a device, the RF antenna having at least one feed pin extending from a proximal end of the RF antenna for electrically coupling the RF antenna to the device through the feed pin, the connector comprising:

a base having a central opening to allow passage of the at least one feed pin of the RF antenna therethrough without the at least one feed pin contacting the connector to allow electrical connection of the feed pin with the device;

a collar that extends from the base for receiving and coupling to the RF antenna; and

a coupling structure that extends from the base and engages the device to facilitate coupling of the antenna to the device; and

wherein

the base and collar are sized and configured to closely receive the proximal end of the RF antenna.

11. The connector of claim 10, wherein:

the coupling structure is formed from spaced apart mounting members that project from the base and are configured to engage and receive at least a portion the device between the spaced apart mounting members.

12. The connector of claim 10, wherein:

at least a portion of at least one of the base and collar are formed from electrically conductive materials that are configured for making electrical contact with the RF antenna; and

at least a portion of the coupling structure is formed from an electrically conductive material and is in electrical contact with said at least a portion of said at least one of the base and collar.

13. The connector of claim 10, wherein:

the coupling structure is formed from a pair of spaced apart mounting members that project from the base and are configured to engage and receive at least a portion the device between the spaced apart mounting members, the inward faces of the spaced apart mounting members being located to one side of a centerline of the connector that passes through the center of the central opening.

14. The connector of claim 10, wherein:

the connector is configured as an end-mount connector wherein the connector is configured to couple to the end of a circuit board of the device so that a longitudinal axis of the RF antenna is oriented parallel to a plane of the circuit board.

15. The connector of claim 10, wherein:
