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.

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 portable phone unit for use in satellite communication systems has a vertically correcting antenna module pivotally secured to the handset for free rotation about a pivot axis. The module contains a mechanism, such as a gravitational counterweight for urging the module to pivot into a predetermined vertical orientation regardless of the handset orientation. An antenna projects from the module in a direction which is vertically upright when the module is in its predetermined vertical orientation. A mast mounted antenna module can also be used to take advantage of dissimilar antenna segment weights for multiple frequency antennas. As the handset is moved into an angular orientation, the module pivots under the weight of the counterweight, or a portion of the antenna itself, until the antenna is oriented vertically.

Abstract: Un dispositivo de comunicaciones inalámbrico portátil tal como un microteléfono (10, 110) que tiene un modulo de antena verticalmente corregido (34, 134) asegurado pivotalmente al microteléfono (10, 110) para su rotacion alrededor de un primer eje de pivote (40, 140). El modulo de antena (34, 134) puede girarse en una orientacion predeterminada, independientemente de la orientacion del microteléfono. Una antena (24, 124) montada sobre el modulo (34, 134) se orienta verticalmente cuando el modulo (34, 134) se encuentra en una orientacion predeterminada. Cuando el modulo antena (34, 134) se gira para usarse, un mecanismo incorporado en la estructura de soporte del modulo (34, 134) gira automáticamente el modulo de antena (34, 134) alrededor de un segundo eje de pivote (190), el cual se encuentra substancialmente perpendicular al primero (40, 140). Esta segunda rotacion coloca la antena (24, 124) en un ángulo que compensa la inclinacion del microteléfono (10, 110) durante el uso alrededor de un eje paralelo al segundo eje (190), o a lo largo del primero (40, 140). Es decir, por utilizarse la antena (24, 124) se desplaza mediante un ángulo preseleccionado en orientacion vertical, típicamente alrededor de 10-15 grados, en una direccion perpendicular a la primera direccion de rotacion para compensar la colocacion de una bocina y un microfono (26, 28).

Abstract: A DUAL-BAND HELICAL ANTENNA PROVIDES OPERATION IN TWO FREQUENCY BANDS. THE DUAL-BAND HELICAL ANTENNA INCLUDES TWO SINGLE-BAND ANTENNAS BANDS. THE DUAL-BAND HELICAL ANTENNA INCLUDES TWO SINGLE-BAND ANTENNAS (1304, 1308), EACH HAVING A FEED NETWORK (1804, 1808), A GROUND PLANE (412) OPPOSITE THE FEED NETWORK, AND A SET OF ONE OR MORE RADIATORS (104A TO 104D) EXTENDING FROM FEED NETWORK. A TAB (1504) EXTENDS FROM THE FEED NETWORK OF ONE OF THE ANTENNAS WHICH PROVIDES A FEED FOR THAT ANTENNA. THE TAB (1504) 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. THE GROUND PLANE OF ONE ANTENNA IS USED AS A SHORTING RING FOR THE OTHER ANTENNA.
