Problems solved by technology

Currently, the vehicle-mounted 5G antennas on the market are limited to multi-band signal transmission and reception, and most of the feeds are in the form of matching circuits. The bandwidth and antenna efficiency of the antenna need to be improved to achieve 5G full-frequency signal transmission and reception, but the size of the antenna is limited.

Embodiment Construction

[0017] The inventors have recognized that there is a need for smaller (eg, narrower, thinner, etc.) multi-band vehicular antenna assemblies that do not necessarily require complex manufacturing processes to manufacture AM / FM antenna components. In recognition of the above, the inventors have developed and disclosed exemplary embodiments of full-band vehicle-mounted antenna assemblies or systems that are small or compact in overall size and have a narrow or thin upper profile.

[0018] The present invention will be described in further detail below with reference to specific implementations and accompanying drawings.

[0019] Referring now to the attached drawings, figure 1 Exemplary embodiments of antenna assemblies are disclosed that include at least one or more aspects of the present disclosure. As shown, the antenna assembly includes a base 111 and a microstrip antenna plate 112, the feed point 110 is co-located on the base 111 or supported by the base 111, and constitutes...

Abstract

The invention discloses a 5G full-band vehicle-mounted antenna based on a tight coupling technology. The 5G full-band vehicle-mounted antenna comprises an antenna shell similar to a shark fin, and the antenna shell is installed on the top of an automobile, provided with a front screw hole and a rear screw hole, and is small in size and convenient to install; the rectangular base is used for bearing the microstrip antenna plate, the rectangular base is made of a copper sheet plate, the length of the long side of the rectangular base is equal to that of the microstrip antenna plate, and a grounded structure is constructed for the microstrip antenna plate; the microstrip antenna board is used for receiving and transmitting signals in a 5G full frequency band (namely from a low frequency band 617MHz-960MHz to a high frequency band 1710MHz-5000MHz), the microstrip antenna board is characterized by comprising three parts, namely a structure for realizing tight coupling by digging a hole in the middle, a structure for expanding the bandwidth of the antenna by grounding a patch extension line branch knot and a feeding point, and the whole microstrip antenna board is an FR-4 glass fiber board and is erected in the middle of a rectangular base. According to the 5G full-band vehicle-mounted antenna, a structure with a hole dug in the middle is adopted to achieve the effect that the antenna bandwidth is widened through the tight coupling technology, and the antenna efficiency can reach 90% or above through a direct feeding mode.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted antennas, in particular to a 5GB vehicle-mounted 5G full-frequency antenna based on the tight coupling technology. Background technique [0002] With the continuous development of communication technology, the speed and bandwidth of communication are continuously improved, and the types and antenna efficiencies of vehicle-mounted antennas are also updated. At present, the on-board 5G antennas on the market are limited to multi-band transmission and reception of signals, and most of the feeds are in the form of matching circuits. The bandwidth and efficiency of the antenna need to be improved to achieve 5G full-band transmission and reception of signals, but the size of the antenna is limited. SUMMARY OF THE INVENTION [0003] Aiming at the shortcomings of the prior art, the purpose of the present invention is to provide a 5G full-band vehicle antenna with a hollow hole in the middle to r...
