Compared with other types of antenna, microstrip antenna has that structure is simple, section is low, light-weight and easy and transmission network
The advantages that network or integrated other high-frequency elements, so the often primary selection of millimetre-wave radar product.However microstrip antenna
Radiation theory is to carry out electromagnetic radiation by the gap between patch edges and earth plate, above and below feed direction
Two gaps participate in radiation, also commonly referred to as a kind of gap binary array antenna.To reduce microstrip transmission line chromatic dispersion problem and transmission
TEM mode electromagnetic wave, microstrip antenna choose media plate thickness can be much smaller than wavelength, so the beamwidth of antenna of microstrip antenna also compared with
It is narrow, it will be generally less than the 3% of bandwidth of operation.
Automobile-used millimetre-wave radar, generalling use structure, simply cost is relatively low, and (frequency modulation is continuous by the FMCW of suitable proximity detection
Wave) radar system.Radar antenna launches outward out a series of continuous frequency modulation millimeter waves, and frequency presses the rule of modulation voltage at any time
Variation generally uses continuous triangular wave, then receives the reflected millimeter-wave signal of target, by comparing two groups of signals (hair
Penetrate and receive) time difference of same to frequency point (detection static target) determines the distance between target or two groups of signals most
Difference on the frequency between high frequency points determines the relative velocity between target.According to the above working principle, sampled point known to us
More, target range, speed or the relative angle calculated then can be more acurrate.So high-resolution radar system is then wanted
One is asked than wider bandwidth of operation, and microstrip antenna exactly has apparent disadvantage in the beamwidth of antenna.
