DETAILED DESCRIPTION

[0021] The utility model discloses a kind of LoRa antennas, below Preferred Embodiment (Example 1), referring to the Figures 1 to 5 , the specific embodiment of the utility model is further described.

[0022] Referring to the Figures 1 to 5 , Figures 1 to 4 Different perspective LoRa antennas are respectively shown, Figure 5 Cross-sectional structure of LoRa antenna is shown.

[0023] Example 1.

[0024] Preferably, LoRa antenna, including wave-transparent shell 100 and LoRa assembly 200, wave-transparent shell 100 is detachably connected to LoRa assembly 200, wherein:

[0025] LoRa assembly 200 includes coaxially distributed convex shell 210, ring belt 220 and base 230, and the base 230 is provided with base body 240 and inner ring layer 250, first outer ring layer 260, second outer ring layer 270, third outer ring layer 280 and fourth outer ring layer 290 which are integrally formed with base body 240, the bottom of convex shell 210 is fixedly connected with the top of first outer ring layer 260, and the bottom of ring belt 220 is fixedly connected with the top of second outer ring layer 270.

[0026] The first annular groove 261 is arranged between the inner ring layer 250 and the first outer ring layer 260, the second annular groove 271 is arranged between the first outer ring layer 260 and the second outer ring layer 270, the third annular groove 281 is arranged between the second outer ring layer 270 and the third outer ring layer 280, and the fourth annular groove 291 is arranged between the third outer ring layer 280 and the fourth outer ring layer 290. The first annular groove 261 is arranged with a (annular) first LoRa frequency band transceiver (not shown in the figure), the second annular groove 271 is arranged with a (annular) second LoRa frequency band transceiver (not shown in the figure), the third annular groove 281 is arranged with a (annular) third LoRa frequency band transceiver (not shown in the figure), and the fourth annular groove 261 is arranged with a (annular) fourth LoRa frequency band transceiver (not shown in the figure).

[0027] The LoRa frequency band transceivers are arranged in a ring shape and distributed along the circumferential direction of the annular grooves, so that the LoRa frequency band transceivers are prevented from directly contacting each other, and the LoRa frequency band transceivers are better for transmitting and receiving LoRa frequency band signals.

[0028] The convex shell 210 is provided with a convex shell main body 211 and a convex shell extension 212 integrally formed with the convex shell main body 211, the inner ring layer 250 is provided with an inner ring layer extension 251 and an inner ring layer main body 252 integrally formed with the inner ring layer extension 251, and the inner ring layer extension 251 is fixedly connected with the convex shell extension 212, so that the convex shell 210, the first outer ring layer 260 and the base body 240 jointly enclose the base inner cavity 231 located inside the base 230.
