The invention discloses a 5G antenna for a communication terminal, which includes a substrate, a radiation sheet and a coaxial cable. The radiating sheet is located on the surface of one side of the substrate and consists of four radiating parts. The first radiating part includes a feeding area, an interdigital area connected to the feeding area, and a first radiating arm connected to the interdigital area; the second radiating part is symmetrically designed with the first radiating part, and the second radiating arm Electrically connected to the first radiating arm; the third radiating part includes a rectangular radiating piece with a semi-elliptical notch, an L-shaped radiating arm connected to the rectangular radiating piece with a semi-elliptical notch, and a U-shaped radiating arm connected to the L-shaped radiating arm, The U-shaped radiating arm is electrically connected to the first radiating arm; the fourth radiating part is designed symmetrically to the third radiating part, and the two U-shaped radiating arms are electrically connected. The antenna disclosed by the invention has double feeding areas, has two resonant frequencies, has simple structure and good performance, and only needs to be connected to one of the feeding areas during use.
Description
technical field [0001] The present invention relates to the technical field of antennas, in particular to a 5G antenna for communication terminals. Background technique [0002] Technology is changing with each passing day, and communication and information are ubiquitous. The mutual communication between terminal devices mainly depends on antennas for effective transmission. The requirements for antennas are getting higher and higher, such as requiring antennas to have multiple feed points and multiple resonance frequencies. Traditional antennas are often single-frequency, single-feed point, and complex in structure. Therefore, the existing technology needs to be improved and improved. Contents of the invention [0003] Aiming at the problem of single feed point, single frequency and complex structure of traditional antenna, the present invention proposes an antenna with double feed point, double frequency and simple structure. [0004] In order to achieve the above obje...
