摘要:
A novel locking mechanism for mounting a radio to an antenna. The mounting face of a radio is secured to the mounting portion of an antenna. The mounting portion of the radio has a locking ring on which a plurality of radio locking tabs are located at equally spaced positions. The ring can be fixed to the radio, or in another embodiment, is still secured to the radio but can rotate independently. The mounting portion of the antenna has a corresponding number of equidistantly spaced tension springs, which have a plurality of spring fingers. To mount the radio to the antenna, the radio locking ring with radio locking tabs is twisted so that each antenna tension spring is deflected by a corresponding radio locking tab. The engagement of the radio locking ring to the antenna spring fingers secures the radio to the antenna. The deflection force also produces a friction force. The spring fingers allow the deflection and friction forces between the tension spring and radio locking tab to increase step-wise when the radio locking ring is brought into contact with each additional spring finger. This step increase in forces allows a user, when turning the radio, to overcome the forces of each spring finger individually, instead of having to initially overcome both sum forces of one solid spring. When the adaptation of the rotating ring is used and additional polarization feature, is possible that prevents the incorrect polarization installation of the radio and antenna assembly by the user.
摘要:
In an active antenna system, two or more amplification chains are contained on one integrated circuit substrate or in one hybrid circuit. The amplification chains can be connected to at least one of a plurality of radiating elements. The integrated circuit or hybrid circuit can be incorporated into an active antenna connector, which can be electrically connected to a radiating element or a receiver system, for example. A first integrated circuit or hybrid circuit can be exchanged with a second integrated circuit or hybrid circuit in a connector to adjust properties of an active antenna system.

The disclosed embodiments provide devices and methods for securely retaining an antenna to a communications device. The disclosed embodiments include an antenna assembly (10) connectable with a housing (22). The antenna assembly may include a connector having a connector body (14) extending from a first end (38) to a second end (40) and thereby defining a longitudinal axis (28). The first end and the housing include at least one set of corresponding, irreversible engagement members (18, 20, 24, 26) movable one way from an unlocked position and a locked position. In the unlocked position the antenna assembly is movable along the longitudinal axis relative to the communications device, while in the locked position the antenna assembly is not movable along the longitudinal axis relative to the communications device. An antenna (16) is securable relative to the connector body and is connectable with the communications device through an electrical conductor (30). A retainer mechanism (34) having a retainer body (36) may be fixedly positioned relative to the first engagement member to secure the antenna assembly in the locked position. Methods of retaining an antenna assembly in a communications device are also disclosed.

A three-axis antenna positioner has an X-Y over azimuth configuration, and includes an azimuth drive assembly, an X-axis drive assembly, and a Y-axis drive assembly. Each drive assembly is independently operable. The azimuth drive assembly imparts 540° azimuthal rotational motion to an antenna about an azimuth axis. The X-axis drive assembly rotates the antenna about a horizontal X-axis at elevation angles between -90° and +90°. The Y-axis drive assembly rotates the antenna about a Y-axis at elevation complement angles between -2° and +105°. The azimuth axis, the X-axis, and the Y-axis all intersect at a common intersection point, and are mutually orthogonal. A controller operates each drive assembly so as to minimize antenna tracking velocity and acceleration. Each drive assembly may include dual drives, and may be operated in a bias drive mode to substantially eliminate backlash.

摘要:
A first member is formed with a hole having an inner wall formed with a recess at a first circumferential position. A second member is formed with an elastic retainer which is retractably projected from an outer peripheral face of the second member and engaged with the recess when the second member is fitted into the hole. A chamfered portion is formed on an aperture edge of the hole at the first circumferential position, so as to have a width allowing the retainer to pass therethrough when the second member is fitted into the hole.
