Embodiment Construction
[0027] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail below with reference to the drawings and embodiments.
[0028] This embodiment discloses a 24G vehicle-mounted anti-collision radar array antenna, such as figure 1 As shown, it can be used as the transmitting end or receiving end of the 24G vehicle-mounted anti-collision radar antenna. This embodiment takes the transmitting end as an example, and proposes a new type of 24G / 77G impedance matching network design. The impedance applied to the antenna array at the transmitting end The matching form is researched based on the relevant theory of microwave / millimeter wave impedance matching. The array antenna includes a radiation array 1 composed of 5×10 radiation arrays, the radiation array 1 is the radiation part, and an impedance matching network 2 is set on the same plane of the radiation array 1, and the radiation array uses the impedance matchin...
