Embodiment 1

[0034] In this embodiment, a two-way radiating antenna with one transmission and two reception is taken as an example, and it is necessary to perform transmission, reception and detection in a direction perpendicular to the earth and in a direction parallel to the earth. Such as figure 1 As shown, according to the practice of the prior art, two sets of millimeter-wave radar systems, especially two sets of millimeter-wave array antennas are required, and two PCB boards are required for implementation.

[0035] This embodiment provides a bidirectional radiating antenna with one transmission and two receptions, orthogonal bidirectional, such as figure 2 As shown, including the end-fire antenna and the side-fire antenna, the end-fire antenna and the side-fire antenna are set on the same PCB board, and the incident port of the end-fire antenna and the incident port of the side-fire antenna are connected to the power divider, and the power divider is used Used to distribute electr...

Embodiment 2

[0057] The difference between this embodiment and Embodiment 1 is that the number of end-fire antennas is set to be multiple, and multiple end-fire antennas are connected in parallel to form an end-fire antenna array; the number of side-fire antennas is multiple, and multiple side-fire antennas The antennas are connected in parallel to form a side-firing antenna array, thereby realizing the function of multiple transmission and multiple reception on one PCB board, so as to flexibly adapt to the needs of different application environments and improve the performance of the antenna system.

Embodiment 3

[0059] This embodiment provides a communication device, including a two-way radiation antenna as described in Embodiment 1, the orthogonal two-way radar antenna is used for transmitting and receiving detection in a direction perpendicular to the earth and in a direction parallel to the earth Conduct transmit and / or receive probes.

[0060] This embodiment also provides a guardianship assistance device, including the above-mentioned communication device, and applicable frequency ranges include 24 GHz and 30 GHz to 300 GHz.

Abstract

The invention relates to the field of millimeter wave detection, in particular to an antenna with bidirectional radiation capability, which comprises an end-on-fire antenna and a side-on-fire antenna, the end-on-fire antenna and the side-on-fire antenna are arranged on the same PCB, and the included angle between the main polarization direction of the end-on-fire antenna and the main polarization direction of the side-on-fire antenna is 80-100 degrees. According to the millimeter wave radar system, the end-fire antenna and the side-fire antenna are arranged on one PCB at the same time, simultaneous transmitting and receiving in two directions are achieved, one PCB and one set of control system are omitted, and the manufacturing cost of the millimeter wave radar system for achieving bidirectional detection, especially bidirectional detection in the orthogonal direction, is greatly saved.

Description

technical field [0001] The invention relates to the field of millimeter wave detection, in particular to an antenna with bidirectional radiation capability. Background technique [0002] Millimeter wave detection is a very promising new detection method. Compared with ultrasonic detection and infrared detection, it has the characteristics of high accuracy and is not easy to be blocked by obstacles. Millimeter wave radar, as the name suggests, is a radar technology that utilizes millimeter waves with a wavelength of 10mm to 1mm and a frequency of 30-300GHz. The radar spectrum for industrial applications is 60-64GHz and for automotive applications is 76-81GHz. Due to the shorter wavelength of the signal at these frequencies, the size of the radar antenna is also smaller. The small size of the radar, coupled with advanced antenna technologies such as antenna on package (AoP) and antenna on PCB (AoPCB), enables mmWave radar to be widely used in car navigation, building automat...
