Microstrip grid array antenna has been widely used because of its simple structure, low cost, high gain, low profile and other advantages. Microstrip comb array is improved according to the transmission characteristics of microstrip grid array antenna, which removes the transmission long side without changing its function. In this paper, a 24 GHz vehicle mounted antenna based on PCB technology is proposed, which has the advantages of high gain, low sidelobe and narrow beam. Firstly, a microstrip comb antenna subarray is designed, and then 10 subarrays are used to form an antenna array. Chebyshev distribution is used to excite each subarray to obtain the low sidelobe level. Finally, the realized gain of the antenna array can reach 28.8 dBi. At the center frequency of 24.125 GHz, the measured sidelobe levels in the E-plane and H-plane are less than − 15 dB.
