Technical Field

The utility model relates to the technical field of antennas, specifically be a novel thing networking 4G antenna.

Background

An antenna (antenna) is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium, usually free space, or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all use electromagnetic waves to transmit information and work by depending on antennas. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. The antennas are generally reciprocal in that the same pair of antennas can be used as both transmit and receive antennas. The same antenna is the same as the basic characteristic parameter for transmission or reception. This is the reciprocity theorem for antennas.

In the 4G antenna of the existing form, because the antenna of the respective design form is difficult to directly purchase and use on the universality or the adaptability under the limiting conditions of the size, the performance, the use environment and the like of the size, the performance adaptation of the product is required to be designed in a customized manner under most conditions, the original 4G antenna is limited in the aspects of the size, the gain performance and the like under the requirement of the product of the Internet of things, the use requirement of the product cannot be met, and in order to solve the existing problems, a novel 4G antenna of the Internet of things is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel thing networking 4G antenna, possess the little and gain performance strong advantage of size, in the 4G antenna of having solved current form, because design form antenna separately under the size of size, restriction conditions such as performance and service environment, it is difficult to directly adopt on commonality or suitability and use, need the customization design to carry out the performance adaptation of product under most of the circumstances, under the demand of thing networking product, original 4G antenna is limited in aspects such as size, gain performance, can not satisfy the problem of product user demand.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel thing networking 4G antenna, includes the dielectric plate, the skin weld of dielectric plate has resonance oscillator, coupling paster, radio frequency cable inner conductor and radio frequency cable outer conductor, the left side electric connection of resonance oscillator has the coupling paster, and the one end of coupling paster extends to the back of dielectric plate, coupling paster and radio frequency cable inner conductor and radio frequency cable outer conductor electric connection.
