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◦).

Corrections to “A Novel Elliptical-Cylindrical Antenna Array for Radar Applications” [May 16 1681-1688

In [1, p. 1683], in the line one below (4), $P_{n} $ is undefined and should be distinguished from $P_{n} $ in line four at p. 1682. In the sentence one below (4), some statements are incorrect and redundant. The corrected expression of that sentence should be “we can have the maximum possible radiation pattern when $p_{m} =-K\cdot d\cdot \cos (\theta _{0} )$ and $p_{n} =-K\cdot \sin (\theta _{0} )(a\cdot \cos (\phi _{n} )\cdot \cos (\phi _{0} )+b\cdot \sin (\phi _{n} )\cdot \sin (\phi _{0} ))$ .” And in line 7 after (4), $\vartheta $ is undefined and $\vartheta $ should be correct to $\theta $ . Equation (5) is incorrect. The correct equation follows: \begin{equation*} F_{\mathrm{ Hyper}} = \big \{{ ( { | {F_{\mathrm{ Left}}} |+ | {F_{\mathrm{ Right}}} |} )^{k}- ( { | {F_{\mathrm{ Left}} -F_{\mathrm{ Right}}} |} )^{k}} \big \}^{\frac {1}{k}}.\tag{5}\end{equation*}
