Abstract: A vehicular radar auxiliary jig includes a transverse extensible bar, two longitudinal extensible bars and two upright bars. The longitudinal extensible bars are perpendicularly connected to two ends of the transverse extensible bar, respectively. One end of each longitudinal extensible bar is positioned distal to the transverse extensible bar and provided with a tire securing portion. The upright bars are perpendicularly connected to two ends of the transverse extensible bar and are perpendicular to the longitudinal extensible bars, respectively. One end of each upright bar is positioned distal to the transverse extensible bar and provided with a mounting portion, thereby connecting to an electromagnetic wave component. A vehicular radar mounting method and vehicular radar detecting method, each using the vehicular radar auxiliary jig, are provided.

Abstract: The present invention related an asymmetrical yagi representation of dipole UWB antenna herein, said antenna located on a substrate and able to be interconnected to a wireless communication apparatus. The antenna comprising: a first radiation arm, said radiation arm comprising a first feed point, a first branch, a second branch, and a first tail. The second radiation arm comprising a second feed point, a third branch, a fourth branch and a second tail. Said first tail and said second tail point are located at the farthest spot from the first radiation arm and the second radiation arm respectively.

Abstract: A symmetrical matrix representation of dipole UWB antenna, mounted on a substrate and attachable to a wireless communication apparatus, comprises a first radiation arm, said first radiation arm comprising a first feed point, a first branch, a second branch, and a third branch, said first branch, said second branch, and said third branch are spaced in parallel, said first feed point and said second branch are aligned; and a second radiation arm, said second radiation arm comprising a second feed point, a fourth branch, a fifth branch, and a sixth branch, said fourth branch, said fifth branch, and said sixth branch are spaced in parallel, said first feed point and said second branch are aligned; wherein said first feed point and said second feed point are interconnected to a wireless communication apparatus.

Abstract: A multi-band planar inverted-F antenna, adapted for a wireless communication device, is disclosed, which is comprised of: a feeding port, a first radiation area, a second radiation area, a ground area and a connecting port. The wireless communication device is connected to the feeding port through a signal line so as to transmit/receive signal using the antenna. The first and the second radiation areas are connected to the feeding port while being arranged at a same side with respect to the feeding port. The connecting port, being connected to the ground area, is connected to the feeding port while being arranged at a side opposite to the first radiation area with respect to the feeding port. As the structure of the aforesaid multi-band planar inverted-F antenna is simple, it is easy to be manufactured.

Abstract: A digital TV antenna, comprising an antenna cable in a copper tube covered by a plastic coating as an antenna housing, wherein a top end of the digital TV antenna is used as a feed-in terminal of the antenna cable extended to a connector at the other end for electric connection to an external electronic appliance.
