摘要： A magnetic core antenna system including a magnetic core and a winding network. The winding network may be configured with a non-uniform ampere-turn distribution to achieve a desired flux density in the core. The network may include a plurality of windings configured to provide a winding impedance facilitating optimal transmitter power delivery to the windings. A magnetic core may be constructed from multiple components having longitudinal contact surfaces and joined by a transverse clamping force. An air gap may be provided between the components to allow relative movement therebetween.

摘要： A reception antenna is formed of a column-profiled ferrite core and three antenna coils, each of which is formed by winding electric wire around the core. Each central axis of the three antenna coils is mutually disposed orthogonally at a barycenter of the core. Each of the three antenna coils is symmetrical with respect to the barycenter. A third antenna coil and each of a first antenna coil and a second antenna coil are overlapped with a space. The first antenna coil and the second antenna coil are overlapped with direct contact, where a starting end of the second antenna and a terminating end (outward end) of the first antenna is connected.

摘要： The invention relates to a ferrite antenna, comprising at least one winding (4), which is arranged around a core (2) consisting of ferrite material. A second core (3), consisting of ferrite material and running coaxially to the first core (2), is allocated to the first core (2), which carries the winding (4) and is rigidly fixed in the coil carrier (1). Said second core, which can be displaced in an axial direction in the same coil carrier (1), is positioned in such a way that the opposing front faces of the two cores are placed at a predetermined distance from one another. Said distance can be altered by displacing the second core (3) in an axial direction in order to tune the antenna After tuning, the second core (3) can be fixed in or on the coil carrier (1).

摘要： Antennas with steerable antenna patterns and techniques for using such antennas are described. In accordance with the invention, antenna patterns with one or more NULLs are used. Through the use of digital control signals the antenna pattern is steered so that a source of signal interference, e.g., a multipath signal, will be located in a NULL. In this manner the received signal's S/N ratio can be maximized thereby facilitating demodulation. The techniques of the invention can be applied to television, computer devices, mobile devices and a wide range of other systems. Digital commands to control an antenna may include multiple information fields, e.g., a direction field, a channel field, a gain field and a polarity field. Antennas incapable of supporting the specified fields disregard information in fields which are not supported. Information in each supported field is decoded and used to adjust the corresponding antenna characteristic.
