[0032] In this embodiment, please refer to Figure 1 As shown, a mounting cavity is formed inside the protective housing 100, and the antenna assembly 200 and the control circuit board 300 are arranged in the mounting cavity. The protective housing 100 protects the antenna assembly 200 and the control circuit board 300 inside, thereby improving the safety and service life of the antenna assembly 200 and the control circuit board 300. The antenna assembly 200 and the control circuit board 300 are stacked in sequence in the protective housing 100. For details, please refer to Figure 2As shown, the antenna assembly 200 includes a substrate 201, a radiation plate 202 is arranged at the upper end of the substrate 201, and a grounding plate 203 is arranged at the lower end of the substrate 201. The area of ​​the radiation plate 202 is smaller than the upper surface of the substrate 201, so that the upper side of the substrate 201 is exposed from the radiation plate 202. The substrate 201 is provided with a plurality of metallized vias 204 at intervals along the edge of the radiation plate 202, and the metallized vias 204 completely pass through the substrate 201 and are connected to the grounding plate 203. The metallized vias 204 are electrically connected to the grounding plate 203, and one end of the metallized vias 204 away from the grounding plate 203 is coplanar with the radiation plate 202. When the radiation plate 202 is powered on, radiation signals can be generated between the edge of the radiation plate 202 and the grounding plate 203 and the metallized vias 204, thereby achieving the effect of improving the bandwidth and the antenna gain.

[0033] Optionally, in this embodiment, the radiation plate 202 and the ground plate 203 are both copper plates, which are molded by injection molding using copper foil and a low dielectric constant, low loss high frequency material.

The feed pin 205 is welded to the control circuit board 300 and connected to the radiation plate 202. The control circuit board 300 feeds the radiation plate 202 through the feed pin 205, so that a radiation signal is generated between the radiation plate 202 and the ground plate 203.

[0035] Optionally, in this embodiment, the substrate 201 of the antenna assembly 200 is set to a square plate structure with a length of 55mm, a width of 55mm, and a height of 10mm, and a low dielectric constant, low loss high frequency plate is used for integral injection molding with the radiation plate 202 and the ground plate 203, and the metallized vias 204 are arranged around the radiation plate 202 at intervals to achieve the bandwidth of the antenna, which can cover the requirements of the L band of TX: 1626.5MHz to 1675MHz and RX: 1518MHz to 1559MHz, and can also cover the frequency band of GNSS L1: 1559MHz to 1606MHz.

[0036] Optionally, in this embodiment, two penetrating feed pins 205 are provided on the substrate 201, and the radiation plate 202 is fed by the two feed pins 205. The two feed pins 205 are combined by a 3DB bridge phase shift, so that the antenna can produce right-hand circular polarization characteristics and a wide axial ratio bandwidth. The use of circular polarization in the antenna assembly greatly improves the anti-interference and anti-multipath capabilities of the signal.

[0037] Optionally, in some implementations of this embodiment, the protective shell 100 includes a bottom plate 101 and an upper cover 102 that are detachably connected, the area of ​​the bottom plate 101 is larger than the area of ​​the antenna assembly 200, and the bottom plate 101 can reflect the radiation signal of the antenna assembly 200, the antenna assembly 200 and the control circuit board 300 are installed on the bottom plate 101, and are both arranged inside the upper cover 102.

After the antenna assembly 200 and the control circuit board 300 are installed, the upper cover 102 is buckled for protection. When the antenna assembly 200 or the control circuit board 300 is damaged, the upper cover 102 can be opened for maintenance, thereby improving the service life of the device. Since the upper cover 102 and the bottom plate 101 are detachably connected, a gap is formed between the upper cover 102 and the bottom plate 101, which may cause liquid to penetrate into the inside of the protective housing 100 and damage the electronic components. Therefore, a sealing ring 400 is provided in the upper cover 102, and the sealing ring 400 is located at the connection between the upper cover 102 and the bottom plate 101.

It can be understood that when the non-terrestrial network signal transmission antenna provided in this embodiment is installed, the bottom plate 101 is usually fixed to an external device, and the upper cover 102 is exposed to the outside to avoid blocking the signal of the antenna assembly 200. In order to ensure the safety of the antenna assembly 200, a buffer protection pad 600 is provided between the upper cover 102 and the antenna assembly 200 to protect the antenna and prevent the antenna from vibrating violently or being damaged by external impact.
