“…For instance, we can use optimization algorithms to design a shaped radiation pattern of the antenna array according to a specific application scenario [5][6][7], which quickly can save time and effort. Different array synthesis methods can also be used to achieve the goal [1,[8][9][10]. For example, antenna arrays with a sector beam pattern are designed on the premise of maintaining controllable excitation amplitude and phase according to the Woodward-Lawson array synthesis method [8].…”

“…For example, antenna arrays with a sector beam pattern are designed on the premise of maintaining controllable excitation amplitude and phase according to the Woodward-Lawson array synthesis method [8]. The Taylor synthesis method [9] and the Chebyshev synthesis method [1,10] are used to design antenna arrays with low sidelobes and high gain patterns. C. Wang, Y. Chen and S. Yang propose a planar antenna array with flat-top and sharp cut-off radiation patterns and the half-power beamwidth (HPBW) of the array in both the H-plane and E-plane exceeds 45 • , but its gain is low [11].…”

In this paper, a planar millimeter wave radar array antenna with flat-top pattern is proposed for wide detection angle. Firstly, the Chebyshev synthesis method is used to design the linear array with high gain and low sidelobe pattern which works in the 24 GHz frequency band. The maximum gain of the linear array is roughly 15 dBi, and the main-sidelobe ratio is close to 20 dB. By setting the excitations and phases distribution of the planar array feeding network, a 5××4 antenna array with a flat-top pattern is obtained. The simulated and measured results show that the radar antenna array has a wide half-power beamwidth of 88 degrees, which can ensure that the automotive radar has a longer detection range and a larger monitoring angle.

To reduce the sidelobe level (SLL) and widen the bandwidth, this paper uses the differential evolution algorithm to optimize the array element spacing and excitation amplitude, and designs an 8element coupled microstrip array antenna with non-uniform spacing and variable groove length. Based on the power equally divided feed network, the non-uniform length of the groove to achieve a quantitative change in the excitation amplitude. This method does not need to adjust the width of the microstrip line of the feed network one by one, nor is it limited to an array of equal spacing, which simplifies the complex design process. And to establish a mathematical relationship of all feeder segments to ensure that all array elements are in phase excitation under unequal spacing conditions. At the same time, the H-groove coupling feed form reduces the antenna Q value and increases the bandwidth. The measurement results show a gain of 16 dBi and an SLL of-19.5 dB within the operating bandwidth. And the antenna has a voltage standing wave ratio of less than 1.5 in the range of 13.84 to 15.62 GHz, which meets the bandwidth requirement of SatCom on-the-move. INDEX TERMS Coupled feed, differential evolution algorithm, low sidelobe, microstrip antenna arrays, non-uniform spacing.
