Design of a 2D MIMO Radar Antenna for 77 GHz Automotive Application

In this paper, we propose the design of a 2D automotive MIMO Radar antenna. The antenna design composed by 3 transmitter (Tx) and 5 receiver (Rx) antenna elements. The individual Tx/Rx antenna system is a seven-element series fed modified binomial tapered array with side lobe level (SLL) less than 16 dB and 80
⁰
azimuth field-of-view (FoV). The 2D virtual array formation of the proposed antenna system is discussed. It is shown that the proposed antenna configuration exhibits both azimuth and elevation angular resolution such as 5.82
⁰
and 44.8
⁰
rather than its 1D counter part having same number of antenna elements.
