Patent number: 6191752Abstract: High frequency (HF) antennas for wideband signals are used in the tracking of railcars. These are rugged antennas especially adapted to the hostile environment of a railcar. One antenna is in the form of a magnetic loop. Another generates an electric field produced by a plate mounted just below the railcar undercarriage with an optional dielectric slab situated between the plate and the undercarriage. The antennas need not be specified in terms of optimal parameters since the approach taken is to provide a generic antenna structure adapted to being fitted underneath the carriage of a railcar. This generic structure exhibits a mitigated Q and is capable of broadband tuning. This feature makes the antenna easier and less costly to produce in large quantities and facilitates use of a standard fitting mechanism and installation procedure.Type: GrantFiled: November 29, 1999Date of Patent: February 20, 2001Assignee: General Electric CompanyInventors: Howard Leroy Lester, John Erik Hershey

Patent number: 5005021Abstract: An antenna unit for an automotive vehicle is provided. This antenna unit is adapted to be located in a non-visible position on a vehicle and includes an grounding plate, a radiating conductive plate, and a loop antenna element which is interposed between the plates and is fixed thereto.

Patent number: 4968984Abstract: A bar-type antenna unit is installed at a normally non-visible point on the lower side of a vehicle body. The unit includes an antenna element, a metal plate, and noise shielding means. The metal plate functions to adjust the reactance of the antenna to obtain a desired sensitivity and protects the antenna from water, mud, or snow splashed from the vehicle's wheels to ensure good insulation between the vehicular body and the antenna element. By selecting capacitance of the metal plate, the length of the antenna can be shortened without reducing sensitivity of the unit. The shielding means shields the antenna from noise generated by for example an engine or electrical equipment which would otherwise interfere with radio broadcasts.Type: GrantFiled: June 29, 1988Date of Patent: November 6, 1990Assignee: Nissan Motor Company, LimitedInventors: Kouichiro Katoh, Hiroyuki Kamishima, Hiroshige Fukuhara

Patent number: 4866453Abstract: A slot antenna is disclosed for a horizontal dielectric vehicle door in which the ground plane of the antenna sheet does not connect with or overlap the surrounding electrically conducting vehicle body panels but which nevertheless maintains significant RF currents at FM frequencies through the vertical roof pillars of the vehicle. This is accomplished by the formation of a parasitic slot surrounding the antenna slot in the gap between the sheet and the surrounding sheet metal at the trunk opening. The parasitic slot has a first portion of length substantially the same as that of the antenna slot and a similar width and a second portion of a greater width effective to comprise an open circuit for currents. Thus the total effective length of the parasitic slot is equal to that of the antenna slot for similar resulting current flow from the decklid area through the vertical roof pillars; and the desirable FM performance is preserved.Type: GrantFiled: February 9, 1989Date of Patent: September 12, 1989Assignee: General Motors CorporationInventors: Louis L.

Patent number: 4845506Abstract: A side-looking array antenna system is disclosed in which the inclination angle of the antenna main beam is determined depending on the intervals of a plurality of antenna elements forming an array. A switch is provided to selectively connect one of the ports of an antenna feeder to a signal source or the like. The switch is used to select one of the ports of the antenna feeder as an excitation port, thereby reversing the direction of inclination of the antenna main beam. The antenna main beam can thus be directed in either of the two directions by the operation of the switch. Also, by using this antenna system, a Doppler radar vehicle speedometer with small calculation error, automotive radar and the like may be simply configured.Type: GrantFiled: June 27, 1986Date of Patent: July 4, 1989Assignee: Nippondenso Co., Ltd.Inventors: Yoshihisa Shibata, Hiroshi Mizuno
