  • Patent number: 6920344
    Abstract: There is provided a portable communication device for minimizing the SAR of electromagnetic waves. In the portable communication device, a slim upper housing has an FBC on which a keypad is mounted, a lower housing is vertically spaced from the slim upper housing by a predetermined distance and includes a PCB assembly, and a middle housing is positioned between the slim upper housing and the lower housing, spatially isolated from the lower housing by a separation plate to minimize the adverse effects of electromagnetic waves generated from the PCB assembly, and has a slot opened from the front end to hold an object in the lengthwise direction. A sliding battery pack is insertable to and detachable from the middle housing in the lengthwise direction.

  • Patent number: 5999142
    Abstract: A first antenna configuration contemplates a body housing and an antenna cap positioned at a top portion of the body housing. A helical winding is disposed within the antenna cap for radiating electromagnetic waves. A reflecting plate is installed within the antenna cap at a spaced-apart distance from the helical winding for reflecting the electromagnetic waves in a direction away from a user. Polyacetal material is disposed within the antenna cap for supporting the reflecting plate.

  • Patent number: 5731791
    Abstract: An antenna configuration for a portable radio set provides a helical antenna, a rod antenna and an antenna connecting device that selectively connects the two antennas to a printed substrate to enable their operation. When the rod antenna is partially retracted within the interior of a body housing beyond a threshold point where the antenna connecting device becomes electrically disengaged from the rod antenna, the antenna connecting device elastically returns to an original position and becomes electrically connected to the helical antenna. Alternatively, when the rod antenna is fully extended from the body housing, the antenna connecting device is electrically connected to the rod antenna. The present invention provides advantages in that a large amount of radiating power may be distributed in accordance with the length of the rod antenna, thereby minimizing any radiating interference caused by a user's body and reducing the loss of radiating power.
