Patent number: 8098210Abstract: A method of matching a receive-only antenna (60) for use in receiving video signals in which measurements made on a transceiver's antenna (14) when in an transmitting mode are used in matching the receive-only antenna. The ratio of the amplitude of the reflected signal to the strength of the transmitted signal strength is used not only in selecting components for matching the transceiver's antenna (14) but also in selecting components for matching the receive-only antenna (60). The ratio may be applied to respective look-up tables (54, 64) for selecting the components to be used in matching the respective antennas.Type: GrantFiled: September 8, 2005Date of Patent: January 17, 2012Assignee: EPCOS AGInventors: Peter J.

Patent number: 7835776Abstract: A wireless terminal comprises a ground conductor (1102) and a transceiver coupled to an antenna feed, the antenna feed being coupled directly to the ground conductor (1102). In one embodiment the ground conductor is a conducting case (1102). The coupling may be via a parallel plate capacitor (504) formed by a plate (506) and a surface (1108) of the case (1102). The case (1102) acts as an efficient, wideband radiator, eliminating the need for a separate antenna. In a modification of this embodiment a slot (1112) is provided to increase the resistance of the case (1102) as seen by the transceiver, thereby increasing the radiating bandwidth of the terminal.Type: GrantFiled: July 25, 2001Date of Patent: November 16, 2010Assignee: NXP B.V.Inventors: Kevin R.

Patent number: 7187338Abstract: An antenna arrangement includes aground conductor (302) incorporating two slots (304a,304b) having an electrically small separation and connections (308a,308b) for coupling a transceiver to each slot to enable the ground conductor to function as two substantially independent antennas. Such a device enables efficient diversity performance to be obtained from small volume. The ground conductor, slots and transceiver are integrated in a module (206) adapted for connection to a further ground conductor which provides the majority of the antenna area. The further conductor would typically be a printed circuit board ground plane or mobile phone handset. Matching and broadbanding circuitry may conveniently be incorporated in the module. By varying the area of the connections between the module and the further ground conductor, the resonant frequencies of the slots can be modified.Type: GrantFiled: August 29, 2003Date of Patent: March 6, 2007Assignee: NXP BVInventors: Kevin R.

Patent number: 6909911Abstract: A capacitively back-coupled wireless terminal (10) comprises a PCB (22) having a ground conductor (24) on one surface. A back coupling capacitor (C) is carried by the ground conductor. An elongate slot (30) is provided in the ground conductor to widen the bandwidth. An electromagnetic shield (32) is provided on the side of the PCB (22) which in use is facing a lossy dielectric in order to reduce the SAR. The shield is disposed adjacent to, but spaced from, the slot (30) in the ground conductor and the back coupling capacitor. For narrowband operation the slot may be omitted and/or the spacing between the PCB (22) and the shield (32) may be reduced.Type: GrantFiled: August 13, 2002Date of Patent: June 21, 2005Assignee: Koninklijke Philips Electronics N.V.Inventors: Kevin R.

Patent number: 6680707Abstract: An antenna is set in an antenna mounting of size and shape such that the antenna may be accommodated at least in part in the naturally occurring dip between a persons shoulder blades at the upper part of the back. The mounting includes supporting straps which extend during use from that part of the mounting hosting the antenna, over the shoulders of the wearer and down the front of the wearers torso. The antenna mounting is provided in a garment (not shown) suitable for wearing about the upper part of the body. By extending the support straps over the wearers shoulders in this way, the weight of the straps serves to counter balance the weight of the antenna and mounting to provide more even weight distribution of the antenna and mounting combined between the front and back of the wearer, so as to be centered about the wearers shoulders.Type: GrantFiled: January 11, 2002Date of Patent: January 20, 2004Assignee: Koninklijke Philips Electronics N.V.Inventors: Juliette Allen, Peter J.

Patent number: 6645008Abstract: A connector device is provided in the form of a main body component having a lower surface covered with a conductive layer to provide a ground plane and an upper surface carrying a conductive strip portion to form a microstrip line. The combination of the first conductive surface region (ground plane) and second conductive surface region (microstrip line) separated by the main body component dielectric forms a microstrip section. The conductive layer and strip portion are each connected to a conductor of co-axial feed cable. The device is inserted between conductive layers of an antenna of laminar construction, such a as planar inverted F antenna to establish electrical connection between conductors of the feed cable and conduction layers of the antenna. The connector is secured to the antenna by sewing or adhesive. The antenna is normally positioned in a garment.Type: GrantFiled: January 8, 2002Date of Patent: November 11, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Peter J.

Patent number: 6433743Abstract: A patch antenna (10) for mobile telecommunications use is designed for incorporation into the garment of a wearer, e.g. in a shoulder pad (10) or lapel (30). The antenna comprises first and second (12, 16) spaced layers of electrically conducting fabric with a layer (14) of insulating fabric between, and a connection between the conducting layers. The conducting layers (12, 16) may be a single strip of shaped fabric (A, B, C) folded around the insulating layers. The conducting layers are shaped so that the layer adjacent the wearer is of larger area and is connected as the ground plane of the antenna so as to shield the wearer from the strongest electrical fields. Also, the patch antenna is arranged so that its radiating regions (24, 38) are remote from the user's head.Type: GrantFiled: November 22, 2000Date of Patent: August 13, 2002Assignee: Koninklijke Philips Electronics N.V.Inventors: Peter J.
