In this paper, a new millimeter-wave transmit/receive antenna module for radar sensors was proposed. This antenna was designed operating at 24 GHz and intended for obstacle detection and short-range automotive applications. The transmitting part was implemented by a microstrip array antenna with 48-elements and improved with the concern of nonhomogeneous weights for amplitudes excitation. The receiving part consisted of two independent microstrip arrays in order to support multi-channel signal receiving. The feed networks were optimized for impedance matching. This module had a dimension of 73×64 mm2, which made it easy to install and integrate on the automobiles. The simulation results showed its good performance in automotive radar applications.
