Patent number: 7075491Abstract: The invention is directed to methods, devices and systems for receiving satellite radio broadcast signals by a portable device with multiple complementary antennas. Portable device, as used herein, indicates a device having a size that may be conveniently carried by a person in the fashion of portable AM/FM radios, CD players, MP3 players, etc. For example, the device may be clipped to an article of clothing. The invention particularly concerns a portable device antenna system for receiving a satellite radio broadcast. In an embodiment of the invention, a portable satellite radio device includes primary and supplemental antennas. The primary antenna covers a substantial portion of the azimuth direction and a vertical elevation within the range of about 20 to 60 degrees of vertical elevation. In one embodiment the primary antenna is a circularly polarized antenna. In use, however, part of the coverage in the azimuth direction will normally be blocked by a body of a person.Type: GrantFiled: February 28, 2005Date of Patent: July 11, 2006Assignee: Amphenol-T&M AntennasInventor: Paul A. Nysen

Patent number: 7006801Abstract: A retractable antenna for a wireless communicator includes an elongate radiator that slides through a helical radiator. An electrical contact alternately contacts one of the elongate radiator and the helical radiator depending on a position of the elongate radiator relative to the helical radiator. Mechanical disengagement is accomplished by the movement of the elongate radiator into a contact position with the electrical contact to disengage the helical conductor. A preferred feature of the antenna is that one of the helical radiator and elongate radiator make electrical contact with the wireless communicator circuits, even when the antenna is placed between a fully refracted and fully extended position. Multiple band operation is another feature of the retractable antenna due to its periodic nature. Ease of assembly is achieved through preferred individual snap fit components.Type: GrantFiled: July 17, 2001Date of Patent: February 28, 2006Assignee: Amphenol-T & M AntennasInventor: Christopher C. Lang

Patent number: 6573869Abstract: A multiband PIFA (planar inverted-F) antenna. A preferred embodiment makes use of a spiral slot. The spiral slot is formed to cause multiple frequency dependent nulls in the antenna's electric field modal distribution. The preferred embodiment antenna has a single element patch radiator formed on a dielectric support in an inverted-F relationship with a first ground plane. The dielectric support may be part of a device housing or internal board, e.g., a PCB board. The patch radiator includes a spiral slot. A feed is made to the single element patch radiator in a location relative to the spiral slot to ensure that portions of the single element patch radiator enclosed by the spiral slot are fed as a series extension of another portion of said patch radiator. According to a preferred embodiment, the patch radiator may be formed from a single conductive sheet, plating or deposit along with the shorting post and feed.Type: GrantFiled: March 21, 2001Date of Patent: June 3, 2003Assignee: Amphenol - T&M AntennasInventor: Thomas G. Moore

Patent number: 6380898Abstract: The present invention is a dual mode antenna. The antenna of the invention connects in an inverted-F feed when in a retracted position, and in a monopole feed in an extended position. The antenna mounts adjacent a relatively large ground plane, such as a grounding shell or EMI shield included in a laptop computer display, for example. A preferred antenna includes an elongate radiator mounted in a non-conductive housing to permit retraction and extension of the elongate radiator. The housing includes electrical contact points that form an inverted-F feed antenna connection to the elongate radiator when the elongate radiator is in a retracted position. The electrical contact points form a monopole feed antenna connection to the elongate radiator when the elongate radiator is in an extended position.Type: GrantFiled: August 3, 2000Date of Patent: April 30, 2002Assignee: Amphenol - T&M AntennasInventors: Thomas G.

Patent number: 6369775Abstract: A preferred compact antenna assembly of the invention includes a nonconductive hollow core plug. The core plug has a recessed pattern on an outside surface into which a helical radiator is wound. An end portion of the helical radiator extends through a hole in the core plug to contact a center radiator extending in the hollow portion. A cover covers the helical radiator. Preferably, the entire assembly is configured to snap-fit together and to a device. The cover and core plug may snap-fit together. The bottom of the core plug may define a mount and the center radiator may be exposed from the mount as a device contact. The center radiator is also preferably shaped to grab onto the helical radiator. The recess pattern and hole on the core plug allow formation of the helical radiator having the exact pitch defined by the recess pattern by inserting a wire into the hole and applying pressure to the wire while rotating the core plug and wire vis a vis each other to wind the wire into the recess pattern.Type: GrantFiled: September 25, 2000Date of Patent: April 9, 2002Assignee: Amphenol-T&M AntennasInventors: Thomas G.
