A New Approach of Applying Chebyshev Distribution of Series Fed Microstrip Antenna Array for Radar Applications

In this paper, a new method of applying Chebyshev distribution for series-fed antenna array was proposed for radar applications. The first part of this study consists of applying the proposed method on antenna arrays working at 2.3 GHz (S-band radar applications) with 6, 8, 10, 14, and 28 elements, whereas the second part of the study is applying the method on antenna arrays working at 5.2 GHz (C-band radar applications) with the same number of elements. The achieved sidelob level is around (19.6- 24 dB).The obtained antenna gain is around (10-17.4 dB) depending on the number of elements. Whereas the horizontal half-power beamwidth is around (7◦ – 20◦).
