Square notch ground plane binomial chebyshev for maximum main lobe frequency 9.3 GHz radar application

In this paper, was developed on how to increase the difference between the main lobe to the side lobe antenna, because if the side lobe antenna is very large, will lead to a huge influence on the performance of object detection by the main lobe. With side lobe magnitude would be no confusion, and detecting the wrong object. In this paper the authors do modification method development, by adding a notch on the side of the ground plane, resulting parameters are very nice and can be used in radar applications. With VSWR produced by 1,004, return loss of −54 dB, and the difference between the main lobe and the side lobe by 25, 74 dB. Designed antenna at a frequency of 9.27 GHz–9.33 GHz.
