Balanced Microstrip Folded Dipole Antennas And Matching Networks
US Patent:
8102327, Jan 24, 2012
Filed:
Jun 1, 2009
Appl. No.:
12/475757
Inventors:
Karin Anne Johnson - Palm Harbor FL, US
Assignee:
The Nielsen Company (US), LLC - Schaumburg IL
International Classification:
H01Q 9/26
US Classification:
343803, 343700 MS
Abstract:
Balanced microstrip folded dipole antennas and matching networks are disclosed. In some examples, an antenna system includes a printed circuit board having first and second dielectric layers, and respective portions of the first and second dielectric layers bound a ground plane. The system further includes a balanced folded dipole, wherein a first portion of the folded dipole is located on the first dielectric layer, and a second portion is located on the second dielectric layer. First and second transmission lines are coupled to respective folded dipole portions. A matching network includes first and second portions that are coupled to respective transmission lines and have equal impedances. Each matching network portion includes a tapered first microstrip, having a narrow end coupled to a respective transmission line, a second microstrip coupled to the first microstrip, and a third microstrip coupled orthogonally to the second microstrip via a mitered bend.

International Classification:
H04N 21/442
US Classification:
725 14
Abstract:
Methods and apparatus for multi-purpose metering are disclosed. An example method includes acquiring a rate of data transfer to/from the monitored location and comparing the acquired rate of data transfer to a threshold. The example method also includes setting at least one media monitoring device in a first bandwidth mode when the acquired rate of data transfer exceeds the threshold, and setting the at least one media monitoring device in a second bandwidth mode when the acquired rate of data transfer is below the threshold.
Methods And Apparatus To Detect An Operating State Of A Display
US Patent:
2006021, Sep 21, 2006
Filed:
Mar 24, 2006
Appl. No.:
11/388262
Inventors:
Karin Johnson - Palm Harbor FL, US
International Classification:
H04H 9/00, H04N 7/16
US Classification:
725012000
Abstract:
Methods and apparatus to detect an operating state of a display are disclosed. An example device to detect an operating state of a display includes an optical fiber, an optical-to-electrical converter, and a logic circuit. The optical fiber is optically coupled to a light source of the display. The light energy source is configured to emit light. The optical-to-electrical converter is coupled to the light source via the optical fiber and configured to convert light from the light source into an electrical signal. The logic circuit is coupled to the optical-to-electrical converter and configured to generate an output signal indicative of the operating state of the display based on the electrical signal.
Balanced Microstrip Folded Dipole Antennas And Matching Networks
US Patent:
8446331, May 21, 2013
Filed:
Dec 19, 2011
Appl. No.:
13/330318
Inventors:
Karin Anne Johnson - Palm Harbor FL, US
Assignee:
The Nielsen Company (US), LLC - Schaumburg IL
International Classification:
H01Q 9/26
US Classification:
343803
Abstract:
Balanced microstrip folded dipole antennas and matching networks are disclosed. In some examples, an antenna system includes a folded dipole having first and second portions, a first transmission line located on a first side of a printed circuit board, a second transmission line located on a second side of the printed circuit board opposite the first transmission line, the first and second transmission lines being coupled to respective folded dipole portions, and a balanced microstrip matching network comprising first and second portions, the first and second matching network portions coupled to respective ones of the first and second transmission lines.
