Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.
Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
See Fig. 1～6, a kind of waveguide duplexer antenna wave guide port of this utility model one preferred embodiment,
Include main body block 1, shielding cover board 5, coupling iris 2, metal resonant column the 3, first transmitting-receiving metal resonance
Post 4 and the second transmitting-receiving metal resonant column 6, main body block top half is provided with Metal cavity 7, first and receives
Sending out resonator cavity 8 and the second transmitting-receiving resonator cavity 9, Metal cavity 7, first receives and dispatches resonator cavity 8 and the second transmitting-receiving
The edge of resonator cavity 9 is all provided with opening, the opening of Metal cavity 7, the opening of the first transmitting-receiving resonator cavity 8
It is interconnected with the opening of the second transmitting-receiving resonator cavity 9, is provided with metal resonant column 3 in the middle of Metal cavity 7, gold
