Title:
CONFORMAL ANTENNA FOR WIRELESS LOCAL AREA NETWORK TRANSCEIVER
Document Type and Number:
Japanese Patent JPH08298409
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To supply a data link with one mega bit/second for a personal computer across a short range by constituting a housing of two parts formed of insulating materials, and inserting it instead of a PCMCIA memory extended card. SOLUTION: Parts 1 and 2 are linked with a hinge 3, and a plug connector 4 for inserting the part 1 into the other side as the size of a PCMCIA memory extended card is provided. An inside surface 7 of the part 2 forming a picture chamber 6 is coated with conductive coating for shielding the transmitter/ receiver circuit in the picture chamber 6, and an antenna is installed with a strip conductor 8 on the outer periphery. A conductor 9 is provided at the adjacent ends of the conductor 8, and connected with the circuit of the picture chamber 6. The coating of the surface 7 is tuned into the ground plane of the conductor 8. Thus, a computer interface and WLAN(local area network) controller is arranged on the part 1, and the transmitter/receiver circuit operating with carrier frequencies are arranged on the part 2, and both are connected through a cable crossing the hinge 3.
