In this paper, we present a simple design of a feed network for the antenna to achieve a lower side lobe level. Side Lobe Levels (SLL) are critical issues in the detection of an object. Higher side lobe levels can increase the false detection of objects in an autonomous vehicle system. The array is designed and simulated for four different frequencies, one at a time to make it a scalable design. The chosen frequencies are 10 GHz, 15 GHz, 20 GHz, and 24 GHz. The feed network design consists of eight patch elements with an equal power divider and CST studio software is used for simulations. From simulation results, it can be observed that VSWR is equal to 1.26, 1.16, 1.62, and 1.05 at respective frequencies. So, the radiation efficiency can be achieved as -1.14 dB, -0.92 dB, -0.46 dB, -0.41 dB. The results substantiate that proposed design can reduce the SLL more than -24.5 dB in the elevation plane and also it is greater than 14.4 dB at all the aforementioned frequencies.

“…After creating a patch, a uniform power divider is created for equal power distribution in the feed network. The detailed construction and mathematical expression are presented in the previous article (Jamshid et al, 2017). Here we modify the array to make it scalable for different frequencies.…”
