Zusammenfassung:	A personal paging device is housed in a case which has one dimension (length) longer than its width or thickness, and a clip is affixed to a side on a swivel between the ends of the length dimension, which allows the device to be worn on the person in a vertical or a horizontal posture. A radio receiving antenna is carried on a flexible dielectric sheet within the casing, and radio components are enclosed within that sheet. A pair of orthogonally-related antenna loops can be provided on the dielectric sheet. The swivel clip can be arranged to cooperate with these or other antennas in a circular-polarization antenna system, such that in one orientation one or the other of the antennas will be detuned.
