[0034] Please refer to Figures 1 to 4 The present application proposes a microwave direct-introduction microwave solid-state source 10, which can generate microwave power, including a circuit board 100 and a microwave antenna vibrator 200. The circuit board 100 is provided with a radio frequency microstrip line 110 and a microwave transmission waveguide structure 120, and the radio frequency microstrip line 110 is electrically connected to the microwave transmission waveguide structure 120; the microwave antenna vibrator 200 is connected to the microwave transmission waveguide structure 120, and the microwave antenna vibrator 200 is close to or fits with an external microwave resonant cavity, so that the microwave antenna vibrator 200 can output microwaves to the microwave resonant cavity.
[0035] Specifically, the circuit board 100 is equipped with a radio frequency microstrip line 110, which is electrically connected to a microwave transmission waveguide structure 120, optimizing the transmission path of microwave energy from the source to the output end. The microwave transmission waveguide structure 120 receives the microwave energy on the radio frequency microstrip line 110 and guides it to the microwave antenna vibrator 200, effectively reducing the loss caused by traditional radio frequency connectors and cables. The microwave transmission waveguide structure 120 is specifically used for high-efficiency microwave transmission and optimizes the propagation of energy in a microwave solid-state source. The microwave antenna vibrator 200 is close to or fits the external microwave resonant cavity, ensuring that the microwave energy can be directly and efficiently received by the resonant cavity, further reducing the energy loss during the transmission process.
[0036] It should be noted that, by directly integrating the transmission path of microwave energy into the circuit board 100 and using microstrip lines and a specially designed microwave transmission waveguide structure 120, this technical solution significantly reduces the energy loss during transmission. Compared with the traditional transmission method through RF connectors and cables, this direct introduction transmission path reduces the reflection and attenuation caused by connectors and cables, thereby improving the transmission efficiency of microwave energy. By reducing transmission losses, more microwave energy can be effectively transmitted to the microwave resonant cavity, thereby increasing the overall output power of the system.

This design not only provides physical protection to prevent the circuit board 100 and other internal components from being directly affected by the external environment, but also provides a stable support structure for the circuit board 100 and other internal components.
[0043] Please refer to Figure 3 In one embodiment, the second shell 320 is provided with a first through hole 321 , and the microwave transmission waveguide structure 120 passes through the first through hole 321 and is connected to the microwave antenna element 200 .
[0044] Specifically, the first through hole 321 on the second shell 320 provides a passage for the microwave transmission waveguide structure 120 to pass through, ensuring that the microwave transmission waveguide structure 120 can extend from the inside of the shell 300 and connect with the antenna vibrator.
[0045] In one embodiment, the microwave direct introduction type microwave solid-state source 10 further includes a cover (not shown), one end surface of which is disposed on the second shell 320, and the cover is downwardly disposed on the microwave resonance cavity to dispose the microwave direct introduction type microwave solid-state source 10 on the microwave resonance cavity.

This design enables the microwave solid-state source to be directly placed on the microwave resonant cavity, ensuring efficient transmission and focusing of microwave energy.
[0047] In one embodiment, the cover has an inner groove (not shown) and a second through hole (not shown), and the microwave transmission waveguide structure 120 passes through the second through hole and extends into the inner groove, so that the microwave antenna element 200 is disposed in the inner groove.
[0048] Specifically, the microwave transmission waveguide structure 120 passes through the second through hole and extends into the inner groove, so that the microwave antenna element 200 is arranged in the inner groove, providing precise guidance and fixed position for the connection between the microwave transmission waveguide structure 120 and the antenna element.

There are two microwave antenna elements 200, and any one microwave antenna element 200 is connected to the microwave transmission waveguide structure 120, and the two microwave antenna elements 200 are spaced apart.
[0050] Specifically, the two antenna elements are respectively connected to their own microwave transmission waveguide structures 120 and maintain a certain distance in space. This configuration helps to achieve a wider microwave coverage range and optimized energy distribution.
