| 发明名称 | Antenna for a radar detector | ||
| 摘要 | An antenna for a radar detector according to the present invention comprises: a power supply unit; first and second branches branched from the power supply unit; a first band patch antenna connected to the first branch and having first band properties; a second band patch antenna connected to the second branch and having second band properties; a second band stub placed between the power supply unit and the first band patch antenna on the first branch; and a first band stub placed between the power supply unit and the second band patch antenna on the second branch. The antenna for the radar detector according to the present invention may match one power supply unit without damaging the properties of a plurality of antennas that have different frequency properties. | ||

| 主权项 | 1. An antenna for a radar detector, comprising: a power supply unit; a first branch and a second branched from the power supply unit; a first band patch antenna connected to the first branch and having a first band property; a second band patch antenna connected to the second branch and having a second band property; a second band stub placed between the power supply unit and the first band patch antenna on the first branch to prevent a signal of the second band from progressing to the first band patch antenna; and a first band stub placed between the power supply unit and the second band patch antenna on the second branch to prevent a signal of the first band from progressing to the second band patch antenna, wherein the first band stub is positioned to be spaced apart from the power supply unit by a length of ¼ of a guided wavelength of the first band, and the second stub is positioned to be spaced apart from the power supply unit by a length of ¼ of a guided wavelength of the second band, wherein the length of the first band stub corresponds to the ¼ length of the guided wavelength of the first band, and the length of the second band stub corresponds to the ¼ length of the guided wavelength of the second band. | ||
