W-band low-sidelobe series-fed microstrip antenna array based on impedance matching section weighting method
A W-band low-sidelobe series-fed microstrip antenna array is proposed here. Impedance matching section weighting method is used in element series-fed weighting. This feeding method can effectively realise the desired amplitude distribution and sidelobe level of −30.1 dB is obtained in this design. The designed low-sidelobe antenna has great practical value in antenna of W-band portable radar.
