Abstract: A wireless communication casing is an apparatus that conceals wireless communication equipment while maintaining the signal communication between wireless communication equipment and corresponding wireless communication devices. The apparatus includes an upper capsule, a lower shroud, a tubular housing, a stopper, a mounting pole, a support post, and a pulley assembly. The upper capsule covers the tubular housing which surrounds the mounting pole. The lower shroud upholds and encloses the tubular housing. The stopper upholds the mounting pole above the support post. The mounting pole serves as a platform to mount wireless communication equipment. The support post elevates the mounting pole and consequently the wireless communication equipment above the ground. The pulley assembly raises and lowers the tubular housing and the lower shroud along the support post. The pulley assembly facilitates the accessibility of the wireless communication equipment.

The signal feeding element is mounted on the antenna body, and the antenna body can move between a first position and a second position relative to the signal feeding element. When the antenna body is at the first position, the antenna body contacts and conducts with the conducting element to form a loop. When the antenna body is at the second position, the antenna body does not contact with the conducting element. In an embodiment, antenna receives signal well in both position.

Abstract: A selectively coupled two-piece antenna for use in a mobile phone having a casing and radio frequency (RF) communications circuitry includes a composite radiator that is selectively extendable from and retractable into the casing and a communications interface that is connected to the RF communications circuitry. The composite radiator has first and second radiating elements, and a connecting element. When the composite radiator is extended, the connecting element connects the first and second radiating elements. In this position, the communications interface connects the RF communications circuitry to the first and second radiating elements. Thus, the RF communications circuitry transmits and/or receives RF signals through both the first and second radiating elements as a top loaded antenna. However, when the composite radiator is retracted, the connecting element electrically isolates the first and second radiating elements.

A slit is provided in a stopper of an antenna so that the outer diameter can be reduced, and the antenna is inserted directly into a cylindrical section of the radio case from the bottom of the stopper. A plate-like feeding spring is provided at the cylindrical section, and is directly attached to a connection point of a circuit substrate of a radio; one end of the plate-like feeding spring pressingly contacts the side of the stopper of the antenna, thereby forming a feeding mechanism.

Abstract: A compression spring, enclosed within a portion of a guide member, provides a bias force to automatically extend an antenna in response to release of the antenna from a retracted position. The portion of the guide member enclosing the spring is nonlinearly aligned with another portion of the guide member that is adapted to receive the antenna when retracted. The retractable antenna assembly solves the awkward requirement for the use of two hands to extend an antenna on portable telecommunication instruments, without increasing the size or significantly adding to the weight of such instruments.

Advantageously, the antenna system maximizes space by having a hollow blocking end coaxially received about a sleeve retaining the batteries used by the computer. Additionally, the antenna system includes a directional helix antenna rotatable at least 360.degree. by a stepper motor.

The base is itself fitted through a body panel of a motor vehicle, where it is firmly secured in place with appropriate bushing means fitted over the base post and against the top and bottom surfaces of the body panel, by threading a tubular mount onto the top end of the base post. The tubular mount has a flexible body portion which enables the antenna element to tilt, when it is in its extended position, the tilt occurring freely under the impacting force of any external object accidentally hitting against the antenna element during vehicle travel.

Abstract: A telescopic aerial for a radio or television receiver is constructed to facilitate automatic assembly and comprises a plurality of tubular aerial elements surrounding a central stem, the elements are slidable within one another and each has an enlarged lower end, which is housed within the next outermost element, and a radially inwardly directed lip at the upper end. Between each pair of adjacent elements is a freely slidable axially split spring sleeve which frictionally engages the two tubular elements to prevent them from slipping with respect to one another. The enlarged lower ends of the tubular elements are also formed with inwardly bent tabs to limit the inward movement of the next innermost element when the aerial is collapsed.

Abstract: An antenna for simultaneous connection to a citizen's band transceiver, an AM receiver and a FM receiver, particularly suitable for use on a vehicle such as an automobile. The antenna proper is a center-loaded upstanding rod which, in the preferred form, telescopes downwardly to a retracted position where it does not protrude above the ground plane. The antenna proper is connected to a T-connected open stub transmission line and to a FM resonant relatively high impedance signal-carrying transmission line. The former has inductive reactance in the FM band which offsets the capacitive reactance of the relatively short effective length of the antenna proper in the FM frequencies. The signal-carrying transmission line is substantially half wave in length in the FM band so as to reflect impedance at its far end substantially equal to the impedance present at the T-connection.
