Embodiment 1
[0023] Such as figure 1 As shown, a MIMO airborne antenna adopting WiFi and LTE of the present invention includes several WiFi antenna unit array groups 2 and LTE antenna unit 3 arranged on the mounting board 1, and three WiFi antenna unit array groups 2 are arranged in the WiFi antenna unit array group 2. WiFi antennas 21, adjacent WiFi antennas 21 are vertically arranged from top to bottom, and the LTE antenna unit 3 includes a horizontal antenna 31 and a vertical antenna 32. The lower side of the upper end surface of the board 1 is parallel to the side, the vertical antenna 32 is perpendicular to the horizontal antenna 31, and the left and right sides of the vertical antenna 32 are respectively provided with a WiFi antenna unit array group 2, and two adjacent WiFi antenna unit array groups 2 The WiFi antennas 21 on the same horizontal line are perpendicular to each other. The technical problem to be solved by the present invention is mainly: to invent a new antenna for cab...
Embodiment 2
[0028]Screw holes 11 are provided on the end surface of the mounting plate 1 , and the mounting plate 1 is fixed in the nacelle through the screw holes 11 . Through the screw holes, the entire mounting plate can be fixed in the cabin to avoid the sliding of the mounting plate, which will affect the antennas on it, and then affect the signal.
[0029] The installation plate 1 has a length of at least 200mm and a width of at least 120mm. The antennas are mostly dipoles with flat plate reflections, requiring a height of 5-10 mm, and their width and length are preset to meet the setup of multiple antenna groups.
[0030] The frequency coverage ranges of the LTE horizontal antenna 31 and the LTE vertical antenna 32 are 0.7-1 GHz and 1.7-2.7 GHz.
[0031] The WiFi antenna unit array group has a total of 6 dual-band microstrip antennas, covering 2.4-2.5GHz and 5.15-5.85GHz, and each group has 3 antenna units.
Embodiment 3
[0033] This embodiment is optimized on the basis of Embodiment 1. By extending the length of the mounting board and installing WiFi antenna unit array groups of different frequencies on the mounting board, the frequency coverage and influence range of the entire airborne antenna can be effectively improved, and the use of figure 1 The arrangement can effectively make the antenna echoes interact with each other, increase the penetration effect, cover the entire cabin, and effectively penetrate the wall.
