摘要： A self-aiming directional Wi-Fi antenna system includes a directional antenna that is motorized. A motion controller operates the motors to move the antenna position to sources of Wi-Fi radio frequency (RF) transmissions, determines an SSID for each source that satisfies a selection criterion and stores a position data corresponding to each SSID. The directional Wi-Fi antenna is moved to a final position corresponding to the antenna position data for one of the SSIDs stored in memory.

摘要： An antenna apparatus operates as a base station in a wireless network, with a method configuring a transmission beam within such antenna apparatus. The antenna apparatus has a rotatable antenna assembly employing selected transmission beam patterns, and a controller to rotate the antenna assembly altering its azimuth direction. During configuration mode, a sweep operation rotates the antenna assembly to selected azimuth directions. Quality metric determination circuitry determines, for each selected azimuth direction, a link quality metric for wireless terminals based on communication between the wireless terminals and the base station whilst the rotatable antenna assembly is at that selected azimuth direction. Transmission beam determination circuitry determines, from the link quality metrics determined for the wireless terminals at each selected azimuth direction, both a transmission beam pattern and an azimuth direction for subsequent communication with the wireless terminals. The antenna apparatus efficiently self-configures its transmission beam pattern and azimuth direction.

摘要： A tracking device comprises a cam-driven actuator arm by which the declination of an earth station dish is caused to vertically oscillate with a sidereal day cycle. In a second embodiment, the tracker comprises a constant velocity joint interposed between the satellite dish and the elevation frame of the antenna mounting structure. The rotation of the constant velocity joint over a sidereal day cycle will result in tracking of the figure eight path.

摘要： A TVRO satellite dish antenna system mounted on the roof of a parked vehicle automatically determines its location and bearing relative to two geosynchronous satellites and then uses this information to accurately calculate the azimuths and elevations of any other geosynchronous satellites. A magnetic compass generates a magnetic bearing signal for the system. An estimated latitude and longitude for the vehicle are provide by the user based on the approximate geographic location of the vehicle. The estimated positions for a first geosynchronous satellite and a second geosynchronous satellite relative to the satellite dish antenna are calculated from this information. The satellite dish antenna is moved to an initial search position corresponding to the estimated position of the first satellite and then moved in a search pattern until the receiver detects a signal peak for a selected channel. The actual azimuth and elevation of the first satellite are calculated based on the position of the satellite dish antenna upon detecting the signal peak. These steps are repeated for the second satellite. Revised bearing, latitude, and longitude coordinates for the satellite dish antenna are calculated based on the actual azimuths and elevations of the first and second satellites. Finally, the azimuth and elevation of any remaining geosynchronous satellite can be calculated based on the revised bearing, latitude, and longitude coordinates for the satellite dish antenna.

摘要： A receiver connected to the satellite dish antenna receives signals from an electronic compass for generating a magnetic direction signal. The approximate latitude and longitude values of the parked vehicle are displayed and the user of the system manually selects the latitude and longitude coordinates corresponding to the parked vehicle location. The receiver determines an initial search position for the satellite dish antenna based upon the magnetic reading and the entered latitude and longitude values. The satellite dish antenna is moved from an unstowed position to an initial search position. The satellite dish antenna is then moved in a first rectangular spiral search pattern to obtain a rough-tune position corresponding to the detection of a signal peak for a selected audio subcarrier frequency in a selected channel of a target satellite. The frequency selected is not present in corresponding selected channels of satellites near the target satellite. A fine-tune search is then performed and the method calculates all the azimuth and elevation positions of all remaining satellites.

摘要： The attitude of an antenna which is used with an artificial satellite emitting a radio wave is controlled by a combination of the establishment of an antenna attitude in accordance with gyro data, a small range conical scan which is conducted when a reception level is less than a first reference and at or above a second reference and is relatively high for altering the antenna attitude to a direction which provides a higher reception level, and a broader range search scan which is conducted when the reception level is less than the second reference and is relatively low for altering the antenna attitude to a direction which provides a higher reception level. In one manner, in order to reduce an antenna driving time, an antenna attitude is regarded as an optimum if a fluctuation which occurs in the reception level during the small range conical scan is small, and the first reference is updated to a value which is slightly less than a maximum value in the reception levels which are obtained during the conical scan. In second manner, the first reference is a fixed value, and as long as the reception level continuously remains at or above a given value, which may be the first reference, for example, gyro data is initialized at a given time interval in order to prevent an accumulated error in gyro data from increasing. In other words, data representing a start point and a variance from the start point are cleared.

摘要： An antenna system including a single directional antenna having a single directional gain pattern for receiving electromagnetic waves in a certain direction. The orientation of the directional gain pattern is varied to vary the gain of the antenna in directions other than the certain direction in which electromagnetic waves are to be received. The gain is varied at a frequency higher than that of amplitude variations superimposed on the received electromagnetic waves while maintaining the gain substantially constant in the certain direction in which electromagnetic waves are to be received. The antenna gain variations in the directions other than the certain direction are effective to reduce the amplitude of received undesired electromagnetic waves and thereby diminish amplitude variations caused by these undesired electromagnetic waves.
