In this paper, the planar phased array antenna scan blindness characteristic has been analyzed and a novel technique of eliminating the scan blindness for the phased array antenna has been introduced. The scan blindness of the center element has been used to present the entire phased array characteristic. The array scan blindness characteristics have been simulated and analyzed using CST Microwave Studio (CST MWS). The 5×3 planar phased array antenna radiation patterns against the pattern elevation angle direction has been simulated and compiled. The array’s scan blindness has been determined at the angle of approximately 47⁰. The miniaturized capacitive loaded Electromagnetic Band Gap (EBG) has been developed and introduced between the array elements to eliminate the problem. Based on the simulated results, it is shown that the use of a miniaturized EBG is effective in reducing the surface wave effects and eliminates the scan blindness in the array radiation pattern. This novel finding is very useful to improve the antenna directive efficiency for the directional radar and satellite application.

AbstractThis paper presents a wide-angle scanning phased array antenna using high gain pattern reconfigurable antenna (PRA) elements. Using PRA elements is an attractive solution for wide-angle scanning phased array antennas because the scanning range can be divided into several subspaces. To achieve the desired scanning performance, some characteristics of the PRA element such as the number of switching modes, tilt angle, and maximum half-power beamwidth (HPBW) are required. We analyzed the required characteristics of the PRA element according to the target scanning range and element spacing, and presented a PRA element design guideline for phased array antennas. In accordance with the guideline, the scanning range was set as ±70° and a high gain PRA element with three reconfigurable patterns was used to compose an 8x1 array antenna with 0.9 λ0 spacing. After analyzing whether the active element patterns meet the guideline, the array antenna was fabricated and measured to demonstrate the scanning performance. The fabricated array can scan its beam from -70° to 70° by dividing the scanning range into three subspaces. It shows that even if the array antenna has large element spacing, the desired scanning performance can be obtained using the elements designed under the guideline.

The Difference

The influence of radiators basing errors in the flat monopulse phased array antenna with spatial excitation on the beam forming accuracy is researched. The results of calculations of the deviation of the position of the difference radiation pattern minimum depending on the displacement of the antenna array radiators for antenna arrays with diameters from 10 to 100 wavelengths are presented.
