Abstract: A portable wireless communications device such as a telephone handset having a vertically corrected antenna module pivotally secured to the handset for rotation about a first pivot axis. The antenna module can be rotated into a predetermined orientation, independent of handset orientation. An antenna mounted on the module is oriented vertically when the module is in the predetermined orientation. When the antenna module is rotated for use, a mechanism incorporated in the module support structure automatically rotates the antenna module about a second pivot axis which is substantially perpendicular to the first. This second rotation places the antenna at an angle that compensates for tilting of the handset during use about an axis parallel to the second axis, or along the first. That is, the antenna is shifted by a preselected angle in vertical orientation, typically around 10-15 degrees, in a direction perpendicular to the first direction of rotation to compensate for positioning a speaker and microphone for use.

Abstract: A telescoping antenna assembly has a tubular base for securing to a wireless telephone handset and an extendible mast telescopically mounted on the tubular base for movement between an extended position extending out of the tubular base and a retracted position in which at least the majority of the mast is retracted within the tubular base. The tubular base and mast have mating inner and outer surfaces. One of the mating surfaces has a helical groove extending along at least part of its length, and the other cylindrical surface has at least one pin slidably engaged in the groove. The engagement of the pin in the helical groove causes the mast to rotate relative to the base in a first direction as the mast is moved from the retracted to the extended position, and in a second direction as the mast is moved from the extended to the retracted position, uncoiling and then recoiling the antenna feed line so as to reduce stretching and torque on the line.

Abstract: A portable wireless communications device such as a telephone handset (10, 110) having a vertically corrected antenna module (34, 134) pivotally secured to the handset (10, 110) for rotation about a first pivot axis (40, 140). The antenna module (34, 134) can be rotated into a predetermined orientation, independent of handset orientation. An antenna (24, 124) mounted on the module (34, 134) is oriented vertically when the module (34, 134) is in the predetermined orientation. When the antenna module (34, 134) is rotated for use, a mechanism incorporated in the module (34, 134) support structure automatically rotates the antenna module (34, 134) about a second pivot axis (190) which is substantially perpendicular to the first (40, 140). This second rotation places the antenna (24, 124) at an angle that compensates for tilting of the handset (10, 110) during use about an axis parallel to the second axis (190), or along the first (40, 140). That is, the antenna (24, 124) is shifted by a preselected angle in vertical orientation, typically around 10-15 degrees, in a direction perpendicular to the first direction of rotation to compensate for positioning a speaker and microphone (26, 28) for use.

Abstract: A dual-band helical antenna provides operation in two frequency bands. The dual-band helical antenna includes two single-band antennas, each having a feed network, a ground plane opposite the feed network, and a set of one or more radiators extending from feed network. According to one aspect of the invention, a tab extends from the feed network of one of the antennas which provides a feed for that antenna. The tab also provides a path for current to flow from the radiators of the second antenna along the axis of the second antenna to thereby increase the energy radiated in the directions perpendicular to the axis. According to another feature of the invention, the ground plane of one antenna is used as a shorting ring for the other antenna.
