Embedded wafer level packaging (EMWLP) technology is proposed to eliminate the use of wire bonding, which not only introduces significant radio frequency loss, but also occupies large. The designed antenna which has low sidelobe level is designed using the concept of Taylor pattern synthesis and genetic algorithm. The solution combines a robust hardware design and automotive. When it is used in an automotive radar comprising one transmitter and multiple identical receivers, it can meet the demands of both long-range and medium-range detections without switching the operation mode back and forth between the long-range radar scenario and the medium-range radar scenario. The flexibility of this approach in designing antenna arrays is shown by integrating the same antenna element with three different feed networks based on SIW, grounded coplanar waveguide (GCPW), and microstrip (MS) transmission lines. 7 GHz ±1300 MHz Receiver Type Triple conversion Superheterodyne Antenna Type Linear polarized, Self-Contained Antenna.

Compared to the other sensors used in today’s automotive applications, it has several advantages. (which leads to co-channel car-car interference) • Large antennas/arrays being incompatible with car body panels/styling (compared to 60/77/79GHz) •The higher costs of mitigation and deactivation at 24GHz compared to 79GHz Road safety impact 2. antenna at 76 ~ 77 GHz. • Automotive radar must perform in a challenging environment, which will become more challenging as a greater density of advanced driver assist, and autonomous systems, populate roadways • The Radar Congestion Study estimates these level will have significant impact on existing systems, and has tabulated the most. Since the operating frequency band is 76- 77 GHz, the path loss will be significantly high which should be compensated by the antenna performance.
