Filed:

Feb 28, 2002

Appl. No.:

10/085756

Inventors:

Anthony Teillet - Flower Mound TX
Kevin Le - Arlington TX

Assignee:

Allen Telecom Group, Inc. - Solon OH

International Classification:

H01Q 2126

US Classification:

343797, 343853, 343821

Abstract:

An antenna ( ) having a plurality of unitary dipole antennas ( ) formed by folding a stamped piece of sheet metal. Each of the unitary dipole antennas ( ) are fed by two stripline feed systems ( ). Each of these feed systems are separated above and extend over a groundplane ( ) and are separated by an air dielectric to minimize intermodulation (IM). Phase shifters ( ) in combination with a downtilt control lever ( ) are slidably adjusted beneath the respective dividing portions of the stripline feed system to adjust signal phase and achieve a uniform beam tilt having uniform and balanced side lobes. These stripline feed systems can also be formed from stamped sheet metal and which have distal ends bent 90Â upward to couple to the respective dipole antennas ( ).

US Classification:

343810, 343795, 343797

Abstract:

A dual band, dual pole, variable downtilt, 90 degree azimuth beamwidth antenna (). The antenna includes dipole elements () forming both a PCS band and a cellular band antenna. The PCS band antenna has two sections disposed each side of the cellular band antenna, the elements of each being positioned 90 with respect to the other. A microstrip feed network formed upon a common PC board () feeds the respective dipole elements, and has serpentine portions with a corresponding dielectric member slideable thereover to establish the phase of the associated dipole antennas and achieve a linear downtilt of the respective antenna array. A slide rod adjustment assembly () provides unitary movement of the dielectric members between two different slide rods. These dielectric members are secured with adhesive to the respective slide rods to achieve good dielectric control and no use of hardware. The radiating dipole elements are capacitively coupled to each microstrip, and are also capacitively associated reflector element.

Abstract:

A compact portable multifunctional tabletop air purifier used to adsorb the chemical fumes that are vaporized from the nail products. The air purifier is comprised of a main housing on a stationary base, a fan, a particle and chemical filter. This tabletop air purifier design provides powerful air inlet suction. Operating on top of the worktable, the air purifier directly extracts the fumes vaporized from nail chemicals including Acetates, Benzaledehyde, Benzyl Alcohol, Acetone, and etc. The main housing of the air purifier can be rotated up to 180 degrees relative to the base to be used as a fan or an artificial fingernail dryer. The present invention will be useful for both nail workers and the clients.
