Abstract:
In this paper, we design and fabricate a side lobe comb-line fed microstrip antenna array at the frequency of 77 GHz. This antenna can be used in car and also in peripheral protection radars. To design the antenna, a radiating microstrip element on a simple sublayer is first designed and optimized in order to have desirable specification at 77 GHz. Secondly, a one-dimensional array is formed using a row of microstrip antenna array with 32 serried elements. Finally, a two-dimensional antenna array with 16 rows is fabricated and subsequently fed with a waveguide to complete the antenna design.
