Example Embodiment

[0021] Hereinafter, the present invention will be further described in conjunction with the embodiments.

[0022] A K-band microstrip patch antenna array. Three antennas parallel to each other and with the same structure are arranged on a dielectric board. They are a transmitting antenna (1), a first receiving antenna (2) and a second receiving antenna (3). The transmitting antenna (1) Set opposite to the first receiving antenna (2) and the second receiving antenna (3); the dielectric plate is set to be rectangular or square. When the dielectric plate is rectangular, its size is (48×62) mm, and the user can also Adjust the size as needed. The dielectric plate is made of non-conductive non-metallic materials; metalized grounding holes (7) are set around the dielectric plate, a metal ground plate (9) is provided at the bottom of the dielectric plate, and the ground plate (9) is provided around the There is a grounding port (11), where the grounding hole (7) and the grounding port (...

Abstract

The invention provides a K-band microstrip patch antenna array, which belongs to the field of antennas. The dielectric board is provided with three columns of antennas parallel to each other and with the same structure, which are respectively transmitting antennas, first receiving antennas and second receiving antennas; the antennas of each column There are several microstrip antenna units, several 1/4 wavelength microstrip feeders, power dividers and feed ports; there are several impedance converters, several microstrip transmission lines and several feeder bending lines in the power divider ; The bottom of the dielectric plate is provided with a metal grounding plate; the invention designs a K-band microstrip array antenna with stronger anti-interference ability, so that the detection of moving objects is more accurate.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a K-band microstrip patch antenna array. Background technique [0002] There are many application markets for K-band microstrip antenna arrays. Typical applications include speed measurement, distance measurement and angle detection of moving vehicles on expressways, and can also be applied to blind spot monitoring of cars; traffic flow detection, traffic monitoring, and traffic light control; Mobile object detection; safety monitoring device, anti-collision control, engineering reversing radar; parking space monitoring, active safety driving system for automobiles, etc. [0003] In the application of the K-band microstrip array antenna in the automotive anti-collision radar system, the antenna can be installed on the side, front or rear end of the car, the transmitting antenna transmits the signal, and the time difference and angle change between the transmission and reception are proces...
