Abstract
Description
Technical Field
[0001] The present application relates to the field of antenna technology, and in particular to a combined antenna. Background Art
[0002] With the continuous development of mobile communication technology, the scope of wireless spectrum utilization is becoming increasingly wider. To reduce resource waste, a single antenna often needs to simultaneously cover various frequency bands, including low-, mid-, and high-frequency bands (698-960MHz, 1710-2700MHz, and 3300-5000MHz). Currently, 5G (high-frequency) antennas on the market primarily use directional antenna solutions to improve antenna gain and performance. Due to limitations in product structure and size, 4G low-frequency band antennas generally use omnidirectional antennas. Due to their wide bandwidth, full-band antennas generally use omnidirectional antennas, which have significantly lower gain and radiation directivity than directional antenna solutions. To address these issues, a combined antenna is proposed. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solutions:
[0005] An embodiment of the present application discloses a combined antenna, which is characterized in that it includes a high-frequency directional antenna, a low-intermediate frequency omnidirectional antenna and a metal reflector. The transmission end of the high-frequency directional antenna is connected to the transmission end of the low-intermediate frequency omnidirectional antenna through a first transmission line, the grounding end of the high-frequency directional antenna is connected to the grounding end of the low-intermediate frequency omnidirectional antenna through a second transmission line, and the metal reflector is arranged below the high-frequency directional antenna, and the metal reflector is connected to the high-frequency directional antenna through multiple insulating columns.
[0006] Preferably, in the above-mentioned combined antenna, there are four insulating columns, the four insulating columns are evenly arranged, and the two ends of the insulating columns are fixedly connected to the metal reflector and the high-frequency directional antenna respectively.
[0007] Preferably, in the above-mentioned combined antenna, the high-frequency directional antenna and the low-medium-frequency omnidirectional antenna are arranged on the same plane.
[0008] Preferably, in the above-mentioned combined antenna, the metal reflector is arranged in parallel with the high-frequency directional antenna.
[0009] Preferably, in the above-mentioned combined antenna, the insulating column is made of plastic.
[0010] Compared with the prior art, the advantages of the present invention are:
[0011] It adopts the combination of omnidirectional antenna and directional antenna. The low and medium frequency uses omnidirectional antenna, and the high frequency uses directional antenna. The high frequency antenna part is composed of metal reflector, PCB vibrator and plastic support. The low and medium frequency antenna and the high frequency antenna are connected by a transmission line, which improves the gain and radiation directionality of the high frequency band of the traditional full-band omnidirectional antenna.
