Embodiment Construction
[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0033] Please also refer to Figure 1 to Figure 4 , a hermetic package antenna provided by the present invention will now be described. The hermetically sealed antenna includes a metal box body 1 with an open top surface, a glass window 2 sealed on the top surface of the metal box body 1, and a glass window body 2 arranged on the upper surface and / or lower surface of the glass window body 2. The parasitic patch 3 in the center, and the TR component 4 inside the metal box 1 ; a radiation layer 40 is provided in the center of the top surface of the TR component 4 , ...

The invention provides a hermetically sealed antenna and a manufacturing method thereof, belonging to the technical field of wireless communication. A hermetically sealed antenna includes a metal box with an open top surface and a glass window sealed to the top surface of the metal box. , a parasitic patch located in the center of the upper surface and / or lower surface of the glass window, and a TR component located inside the metal box; a radiation layer is provided in the center of the top surface of the TR component, and the radiation layer is used for radiation and excitation Parasitic patches. The hermetically sealed antenna provided by the present invention has a small height difference between the phase center and the edge of the mouth of the metal box, which can effectively reduce the coupling between the radiation signal and the edge of the mouth of the metal box when the phased array deviates from the normal scanning and The signal wave mutual coupling between the airtight package antennas improves the large-angle scanning performance of the hermetic package antennas; it can widen the bandwidth of the hermetic package antennas and improve the radiation efficiency. The invention also provides a method for making the hermetically sealed antenna.
Description
technical field [0001] The invention belongs to the technical field of wireless communication, and more specifically relates to a hermetically sealed antenna and a manufacturing method thereof. Background technique [0002] T / R is the abbreviation of Transmitter and Receiver. The TR component refers to the part between the video and the antenna in a wireless transceiver system. That is, one end of the TR component is connected to the antenna, and the other end is connected to the intermediate frequency processing unit to form a wireless transceiver system. Its function is to The signal is amplified, phase-shifted, and attenuated. In actual use, the TR component needs to be hermetically sealed, that is, the antenna is hermetically sealed. [0003] In the existing hermetic package, the phase center of the antenna is located on the TR component. When scanning the phased array off-normal, the position of the phase center is lower than the upper edge of the metal frame of the pac...
