A kind of microwave antenna medium block radiation head, including PC medium block 2, the top surface of PC medium block 2 are adhesively fixed with gold
Belong to reflex block 3, metallic reflection block 3 is tapered, and the conical surface of metallic reflection block 3 is towards the top surface of PC medium block 2.
Wherein metallic reflection block 3 can be made up of machining, because being a block of metal, intensity is high, with biography
The plated reflective layer of system is more stable compared to performance, runs with capable of guaranteeing microwave antenna lasting stability.And only machine is needed to add
It work and is adhesively fixed two procedures, compared with the process of traditional plating plus spray painting, technique is simpler, and cost is also more
It is cheap.
Further, there are gap 13, the width in gap 13 between the tip of metallic reflection block 3 and the top surface of PC medium block 2
The frequency of degree and microwave antenna is negatively correlated.The width in gap 13 can be by changing metallic reflection block 3 in machining process
Tolerance is realized.
By adjusting the width in gap 13, the utility model can be made to be suitable for more frequency ranges, expand the scope of application.
In practical applications, the width range in gap 13 can be 0.01-0.05mm, applicable frequency range be 5GHz ~
100GHz, the more high then mach precision of frequency range is higher, the width in gap 13 is smaller.
Since it is desired that retention gap 13, so the tip of metallic reflection block 3 is not suitable for directly gluing with the top of PC medium block 2
Fixation is connect, therefore is connected with retaining ring 5, the company of being connected on all side walls of metallic reflection block 3 in the top surface of PC medium block 2
Ring 4 is connect, the setting of connection ring 4 is adhesively fixed in 5 inside of retaining ring, connection ring 4 with retaining ring 5, to complete metallic reflection block 3 and PC Jie
Mass 2 is fixedly connected.
Further, the outer diameter of connection ring 4 is less than the internal diameter of retaining ring 5, and the logical of annular is formed between connection ring 4 and retaining ring 5
