A 77 GHz Series-fed Leaky-Wave Antenna for Automotive Radar System
A $1.5\mathbf{mm}\times 28\mathbf{mm}$ patch leaky-wave antenna (P-LWA) with a high gain and a large beamwidth in H-plane is proposed for 77GHz automotive radars. Four slots were etched on the driven patch to satisfy the beamwidth requirement in H-plane, which acts as the array element. The simulation results show that the proposed antenna can achieve an impedance bandwidth of 1.3% (76-77GHz) and a maximum realized gain of 15.23dBi. Besides, the proposed antenna can offere an HPBW greater than 118.07° in the H-plane.
