Multicoil Helical Antenna And Method For Same

View page
US Patent:
6975280, Dec 13, 2005
Filed:
Jul 3, 2002
Appl. No.:
10/189094
Inventors:
Jatupum Jenwatanavet - San Diego CA, US
Assignee:
Kyocera Wireless Corp. - San Diego CA
International Classification:
H01Q001/36
US Classification:
343895, 343702
Abstract:
A helical antenna is provided that simultaneously resonates at a plurality of frequencies. This antenna comprises a first coil having a first end for termination in a transmission line feed port. A second coil has a first end connected to the first coil second end, and an unterminated second end. In some aspects, a third coil is used, connected to the second coil second end, with an unterminated end. The coils have axial lengths, a wire gauge, and a coil diameter. The axial lengths are approximately equal to a number of turns times a spacing between turns. In addition, the antenna further comprises a first dielectric encompassed by the first and second coils and a second dielectric that encompasses the first and second coils. The antenna resonates at a first frequency and a second frequency, non-harmonically related to the first frequency, in response to the first and second coils.

Tri-Band Antenna

US Patent:
7019696, Mar 28, 2006
Filed:
Apr 5, 2004
Appl. No.:
10/818063
Inventors:
Jatupum Jenwatanavet - San Diego CA, US
Assignee:
Kyocera Wireless Corp. - San Diego CA
International Classification:
H01Q 1/38
H01Q 1/36
US Classification:
343700MS, 343895
Abstract:
A tri-band antenna and method for forming the same are disclosed. The antenna comprises a meander line radiator, a tapered line radiator coupled to the meander line radiator, a straight line radiator coupled to the tapered line radiator, and a dielectric layer. Exemplary meander line, tapered line, and straight line radiators are formed as microstrip structures overlying the dielectric layer surfaces. According to one embodiment, the meander line radiator is formed on the dielectric top surface and is connected to the tapered line radiator on the dielectric bottom surface through a via. The straight line radiator is connected to the tapered line radiator output on the bottom surface, and is unterminated. In one aspect, the combination of the meander line radiator, tapered line radiator, and straight line radiator forms effective electrical lengths corresponding to the cellular frequency band, the GPS frequency band, and the PCS frequency band.

Multiband Monopole Antenna With Independent Radiating Elements

US Patent:
7446708, Nov 4, 2008
Filed:
Oct 27, 2005
Appl. No.:
11/260588
Inventors:
Anthony H. Nguyen - San Diego CA, US
Jatupum Jenwatanavet - San Diego CA, US
Assignee:
Kyocera Wireless Corp. - San Diego CA
International Classification:
H01Q 1/38
US Classification:
343700MS, 343702, 343895
Abstract:
A single-feedpoint multiband monopole antenna is provided with independent radiator elements. The antenna comprises a microstrip counterpoise coupler having a single-feedpoint interface, a first radiator interface, and a second radiator interface. A first microstrip radiator, i. e. a meander line microstrip, has an end connected to the counterpoise coupler first radiator interface, and an unterminated end. A second microstrip radiator, i. e. a straight-line microstrip, has an end connected to the counterpoise coupler second radiator interface, and an unterminated end. The two radiators are capable of resonating at non-harmonically related frequencies. As with the two microstrip radiators, the microstrip counterpoise coupler is a conductive trace formed overlying a sheet of dielectric material. The counterpoise coupler can come in a variety of shapes, so that the overall antenna may take on a number of form factors.

Multipart Case Wireless Communications Device With Multiple Groundplane Connectors

US Patent:
7482982, Jan 27, 2009
Filed:
Feb 16, 2006
Appl. No.:
11/357647
Inventors:
Jatupum Jenwatanavet - San Diego CA, US
Gregory Poilasne - San Diego CA, US
Jorge Fabrega-Sanchez - San Diego CA, US
Vaneet Pathak - San Diego CA, US
Joe Le - Poway CA, US
Assignee:
Kyocera Wireless Corp. - San Diego CA
International Classification:
H01Q 1/24
US Classification:
343702, 343700 MS
Abstract:
A wireless communication device is provided with a multipart case, having electrical interfaces that encourage the flow of radiation frequency ground current between case sections. The multipart case has a first planar groundplane section and a second planar groundplane section. For example, the multipart case design may be a slider, double slider, multiple hinge, flip, or swivel case. The second planar groundplane is substantially coplanar with the first groundplane in a case open position, and substantially bi-planar with the first groundplane in a case closed position. The wireless device also includes an antenna located adjacent the second groundplane section first end. A first and a second interface electrically connect the first groundplane section to the second groundplane section second end (the end opposite the antenna).

Tri-Band Antenna

US Patent:
20040036652, Feb 26, 2004
Filed:
Aug 26, 2002
Appl. No.:
10/228693
Inventors:
Jatupum Jenwatanavet - San Diego CA, US
International Classification:
H01Q001/38
US Classification:
343/7000MS
Abstract:
A tri-band antenna and method for forming the same are provided. The antenna comprises a meander line radiator, a tapered line radiator, a straight line radiator, and a dielectric layer. Each dielectric layer surface has an area of less than 1.0×10square mils (mils). The meander line, tapered line, and straight line radiators are formed as microstrip structures overlying the dielectric layer surfaces. More specifically, the meander line radiator is formed on the dielectric top surface and is connected to the tapered line radiator on the dielectric bottom surface through a via. The straight line radiator is connected to the tapered line radiator output on the bottom surface, and is unterminated. In one aspect, the combination of the meander line radiator, tapered line radiator, and straight line radiator forms effective electrical lengths corresponding to the cellular frequency band, the GPS frequency band, and the PCS frequency band.

US Patent:
20080106476, May 8, 2008
Filed:
Nov 2, 2006
Appl. No.:
11/555783
Inventors:
Allen Minh-Triet Tran - San Diego CA, US
Ernest T. Ozaki - Poway CA, US
Jatupum Jenwatanavet - San Diego CA, US
Gregory Alan Breit - San Diego CA, US
International Classification:
H01Q 1/24
H01Q 9/00
US Classification:
343702, 343745, 343876
Abstract:
The invention utilizes small, narrow-band and frequency adaptable antennas to provide coverage to a wide range of wireless modes and frequency bands on a host wireless device. The antennas have narrow pass-band characteristics, require minimal space on the host device, and allow for smaller form factor. The frequency tunability further allows for a fewer number of antennas to be used. The operation of the antennas may also be adaptably relocated from unused modes to in-use modes to maximize performance. These features of the antennas result in cost and size reductions. In another aspect, the antennas may be broadband antennas.
