HIGH-FREQUENCY TRANSMISSION LINE USING A PRINTED CIRCUIT BOARD FOR THE IMPROVEMENT OF MULTI-BAND ANTENNA PERFORMANCE, CAPABLE OF IMPROVING ANTENNA RECEPTION CHARACTERISTICS

摘要

PURPOSE: A high-frequency transmission line using a printed circuit board (PCB) for the improvement of multi-band antenna performance is provided to connect multiple antennas with a mainboard by using a PCB, thereby improving the rate of space utilization.;CONSTITUTION: A first ground layer (110) is electrically connected with multiple antennas. A first dielectric layer (120) is laminated on the first ground layer. The first dielectric layer is extended in the same direction as the first ground layer. A signal transmission line (130) is extended in the same direction as the first dielectric layer and transmits electric signals of the multiple antennas. A second ground layer (300) is divided into a first ground part connected with a first antenna and a second ground part connected with a second antenna.;COPYRIGHT KIPO 2013
