US Patent:

7209085, Apr 24, 2007

Filed:

Jul 25, 2005

Appl. No.:

11/190103

Inventors:

Corbett Ray Rowell - Mongkok, HK
William H. Darden - Naperville IL, US

Assignee:

Molex Incorporated - Lisle IL

International Classification:

H01Q 1/24

US Classification:

343702, 343700 MS

Abstract:

A mechano-electronic antenna includes an insulating base board having a first face and a second face which are opposite to each other, and a first radiating surface formed on the first face; and a rotating shaft, which is rotationally provided on and gets through the insulating base board, and is near the first radiating surface, and at least one metal branch arm extends outwards from the rotating shaft on the first face of the insulating base board so that the metal branch arm can be electrically connected with the first radiating surface when the rotating shaft is rotated relative to the insulating base board from the first position to the second position. By these means, the geometrical shapes of the antenna are changed to improve the radiating efficiency of the antenna.

Filed:

Apr 9, 2001

Appl. No.:

09/829027

Inventors:

Marko Spiegel - LaFox IL, US
William Darden - Naperville IL, US

International Classification:

H01Q001/38
H01Q001/24

US Classification:

343/7000MS, 343/702000

Abstract:

An antenna structure and assembly are provided, along with a method of fabricating the same. The antenna structure is formed by molding a plateable plastic antenna element in the desired shape of the antenna structure. The molded antenna element is plated substantially entirely thereabout with a conductive metal material. The antenna assembly includes the molded and plated antenna structure attached to a dielectric base structure adapted for mounting on an appropriate support such as a printed circuit board. A contact spring clip is interengaged between the antenna structure and the circuit board.

Appl. No.:

10/480748

Inventors:

William Darden - Naperville IL, US
Marko Spiegel - Lafox IL, US
Kent Regnier - Lombard IL, US

International Classification:

H01Q001/24

US Classification:

343/702000

Abstract:

An antenna system utilizing a pair of antenna modules each having an antenna and a dielectric frame embracing the antenna. A complementary interengaging structure is provided between the frames of the pair of antenna modules to hold the modules together and to maintain the respective pair of antennas in a predetermined relative orientation. The attachment structure is on exterior walls of the frames, whereby the walls and attachment structure provide a dual function of an isolation barrier between the antennas.

US Patent:

56063326, Feb 25, 1997

Filed:

Aug 21, 1995

Appl. No.:

8/517520

Inventors:

William H. Darden - Libertyville IL
Kevin M. Thill - Kenosha WI
Christopher N. Kurby - Elmhurst IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H01Q 904

US Classification:

343790

Abstract:

A dual function antenna structure transceives in first and second modes. A first feed (120) feeds a primary antenna element (110) for operation in the first mode. A second feed (240) connects to the first feed (120). An upper choke (150) and a metal layer (160) are tuned to a wavelength of the radio frequency energy to be transceived in the second mode. The primary antenna element (110) and the metal layer (160) thus realize a secondary antenna element for operation in the second mode. In a portable radio, dual function operation is thus possible by a compact structure by the first and second feeds (120, 140).

US Patent:

Filed:

Jun 19, 1996

Appl. No.:

8/668020

Inventors:

William Herbert Darden - Libertyville IL
Kevin Michael Thill - Kenosha WI

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H01Q 136

US Classification:

343895

Abstract:

Strips (220) of thin metallic material forming pairs of arms on an elongated dielectric tube (110) form a radiator portion of an antenna assembly. A first radiator plate (310) and a second radiator plate (320) are capacitively coupled to respective hot capacitive plate (270) and ground capacitive plate (280) on opposite sides of the dielectric tube and formed in a single etching step to improve manufacturability, reliability and cost of a radio.

Appl. No.:

17/746837

Inventors:

- Yorba Linda CA, US
Byron del Castillo - Eastvale CA, US
William Herbert Darden - Cary NC, US

International Classification:

H01Q 19/30
H01Q 11/08
H01Q 1/48
H01Q 15/02
H01Q 1/38
H01Q 15/14

Abstract:

A system includes a first antenna and a second antenna. The first antenna includes an antenna section. The antenna section includes a first antenna segment, a second antenna segment adjacent to the first antenna segment, and a notch circuit disposed within a notch between the first antenna segment and the second antenna segment. The notch circuit prevents a first frequency of a signal from passing from the first antenna segment to the second antenna segment while allowing a second frequency from the signal to pass from the first antenna segment to the second antenna segment. The second antenna is disposed proximate to the first antenna. The first antenna occupies a second near field region of the second antenna and the second antenna occupies a first near field region of the first antenna.
