Abstract

The invention belongs to the technical field of antennas, and discloses a broadband low-profile dielectric resonant antennaand wireless communication system, a circular disk dielectric device is loaded on the top of a cylindrical dielectric device at the radiating dielectric device, and a circular ring dielectric is loaded under the circular disk dielectric and is in contact with the metal groundplane to form an annular air cavity, so that a new resonant mode is generated between the original two resonant modes, and the wide-band characteristic is achieved. A metal radiate sheet is printed onthat bottom surface of the dielectric plate, and aft the metal patch is fed, the metal radiating sheet is fed to a radiating dielectric device by a probe. Adjust the length of the metal patch so thatthe antenna impedance matching achieves the wideband characteristics. The dielectric resonant antenna of the invention realizes the wide-band characteristic and the antenna with low profile, and effectively reduces the volume of the antenna.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a wide-band low-profile dielectric resonant antenna and a wireless communication system. Background technique [0002] At present, the commonly used existing technologies in the industry are as follows: due to the characteristics of miniaturization, high radiation efficiency, low loss and easy feeding, dielectric resonant antennas have received extensive attention. With the development of modern communication systems, the demand for broadband and miniaturization of antennas is increasing. Therefore, the research on the broadband low-profile dielectric resonant antenna has practical significance. At present, the domestic and foreign methods for widening the bandwidth of dielectric resonant antennas mainly include the use of dielectric resonators with novel structures, the optimization of feeding mechanisms, the use of hybrid antenna structures and the addition of parasitic eleme...
