Method for improving radiant efficiency based on omni-directional base station antenna

Abstract

The invention provides a method for improving the radiant efficiency based on an omni-directional base station antenna. All radiating elements of the base station antenna are arranged on the same central coaxial line and are periodically arranged in a vertically crossed mode, every two adjacent radiating elements are connected through a thin wire, two ends of the coaxial line are filled with dielectric medium in structural form, the middle of the coaxial line is filled with the air, the length of each radiating element arranged on the base station antenna is larger than the half-wavelength of radio waves in the dielectric medium and is smaller than or equal to the half-wavelength of radio waves in the air, and the distance among the radiating elements of the base station antenna is adjusted. The method for improving the radiant efficiency based on the omni-directional base station antenna can improve the radiant efficiency of the base station antenna, effectively expand the coverage area of the antenna, improves communication quality, and meanwhile does not bring about sharp rise of cost.

Description

technical field [0001] The invention belongs to the communication field, and relates to a coaxial omnidirectional antenna for a base station of a mobile communication network based on LTE (Long Term Evolution, long-term evolution) technology, specifically a method for improving radiation efficiency based on an omnidirectional base station antenna. Background technique [0002] The LTE project is the evolution of 3G technology, which improves and enhances the 3G air access technology, adopts OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) and MIMO (Multiple Input Multiple Output) as its wireless network evolution standard. LTE technology needs to use radio waves to transmit information to complete the work of the entire system, and the antenna is the basic device used to transmit or receive radio waves in the system. In the radio system, the radio frequency signal output by the transmitter is sent to the antenna through the feede...

Problems solved by technology

[0004] The current mobile communication has evolved to the LTE stage. The high-standard communication service quality at this stage must put forward high requirements for antennas, and the construction of base station antennas in ever-changing cities, where the electromagnetic field environment is becoming increasingly complex, antennas The working environment is usually more complex, and the antenna transmits electromagnetic signals in the air, which will be subject to multi-faceted fading

The channel is affected by environmental factors such as terrain, temperature, humidity, etc. These aspects will have a negative impact on the communication quality, resulting in a discounted communication effect experienced by the user, or even a very poor communication quality
