Abstract: A noise reduction structure includes an antenna, a noise source, an electromagnetic conductor, and a grounding member. The antenna has a transmission and reception bandwidth. The noise source radiates an electromagnetic wave. Frequency of the electromagnetic wave falls within the transmission and reception bandwidth. The electromagnetic conductor is closer to the antenna than the noise source. The grounding member is disposed at the noise source in such a manner to face the antenna. The grounding member is electrically isolated from the electromagnetic conductor and forms a good grounding path to the noise source. Furthermore, a transmission dock with the noise reduction structure is provided.

Abstract: An antenna structure includes a central grounding line and a spiral antenna. The central grounding line is linear and has two end portions provided with a grounding point and a first open point, respectively. The spiral antenna has two end portions provided with a feeding point and a second open point, respectively. The spiral antenna winds around the central grounding line while extending in the direction from the grounding point to the first open point, with the second open point positioned proximate to the first open point, wherein the spiral antenna and the central grounding line are spaced apart by an axial distance, thereby allowing the antenna structure to receive and transmit a radio frequency signal with circular polarization.
