Multi-axis vertically corrected antenna for handheld wireless communications devices
First Claim
1. Antenna support apparatus for a portable wireless communications device, comprising:
- a support plate pivotally secured to said wireless communications device with a pivot joint for rotation about a first predefined pivot axis with at least one planar support surface which rotates about said first pivot axis;
an antenna module pivotally secured to the support plate with a pivot joint for rotation about a predefined second pivot axis which is perpendicular to the first for placing the module in predetermined orientations about said second axis, independent of handset orientation; and
bias means for urging said support plate to rotate about said first pivot axis so as to provide at least one desired offset in vertical orientation of said first axis about said second axis.

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.
