Description

Metric wave aerial
The utility model discloses a kind of Metric wave aerial, belong to radar, communication antenna technical field.
Generally speaking, after antenna array face size, oscillator size and wavelength were determined, the angle detection scope of antenna (comprising the azimuth and the elevation angle) had just determined that the angle detection scope of this antenna is narrow.In addition, horizontally-polarized electromagnetic wave or perpendicular polarization electromagnetic wave can only be launched or receive to the symmetrical dipole on this antenna array, can not launch simultaneously or reception level and perpendicular polarization electromagnetic wave, thereby influence the serviceability of antenna.
The purpose of this utility model is a kind of Metric wave aerial of design, bigger angle detection coverage is arranged, and can launch or receive horizontally-polarized electromagnetic wave and perpendicular polarization electromagnetic wave simultaneously.
A kind of Metric wave aerial of the utility model design is made up of two linear array antennas at least, and an end of each linear array antenna is linked together by connector, and the other end of each linear array antenna is installed on the installation base surface of antenna.
Described Metric wave aerial is made up of four linear array antennas, and an end of four linear array antennas is linked together by connector, and the other end of four linear array antennas is installed in respectively on the installation base surface of antenna.
Described linear array antenna is made up of oscillator supporter and two antenna oscillators at least, and antenna oscillator is installed on the oscillator supporter.
Described linear array antenna has two oscillator supporters, and two oscillator arms are installed on each oscillator supporter at least, and two oscillator supporters form linear array antenna side by side.
Described antenna oscillator is a symmetrical dipole.
Described antenna oscillator is L shaped symmetrical dipole.
Described antenna oscillator is L shaped logarithm periodic antenna oscillator.
Described antenna oscillator is the cross-shaped symmetrical oscillator.
Have angle between described two oscillator supporters.
The Metric wave aerial that the utility model is designed has following advantage:
1. angle detection wide ranges (comprising the azimuth and the elevation angle).The designed Metric wave aerial of the utility model is tilted to be combined and installed together mutually by several linear array antennas, adjust the relative position and the angular relationship of each linear array antenna, again in conjunction with antenna array size and wavelength, just can obtain required angle detection scope, to satisfy user's different demands.
2. can launch or receive horizontally-polarized electromagnetic wave and perpendicular polarization electromagnetic wave simultaneously.On linear array antenna, adopt L shaped symmetrical dipole or cross-shaped symmetrical oscillator, can make Metric wave aerial emission or reception level and perpendicular polarization electromagnetic wave simultaneously, improved the serviceability of antenna.
3. have the modularization characteristics, manufacturing, easy to use flexible.The designed Metric wave aerial of the utility model is to be the unit with the linear array antenna, by selecting quantity, length, the setting angle of linear array antenna, form a plane triangle (when the quantity of linear array antenna is 2) or the polygonal pyramid bodily form (when's the quantity of linear array antenna is 2 when above) antenna, can form the different antenna of angle detection scope neatly, for the user provides convenience, also be convenient to simultaneously manufacture.In addition, be the unit with this Metric wave aerial, can also form more massive array antenna.
