A novel printed ultrawideband (UWB) CPW-fed Koch fractal slot antenna is proposed. The UWB bandwidth is largely enhanced by the three-iteration Koch fractal slot whose extrusive angle is 900 instead of 600 to obtain better convoluted shape and selfsimilarity. The −10 dB impedance bandwidth is 3400 MHz (1270-4670 MHz) or about 114% in comparison with 1290 MHz (1620-2910 MHz) or about 57% of the referenced square slot antenna. Details of the proposed antenna design and performance are presented and discussed.

“…The large-scale and modular design of vibrating screen will lead to the separation of screen from screen frame [1][2][3]. In the past, the dynamic analysis and improvement of vibrating screen too much focus on the stress, deformation and optimization analysis [4][5]. No one focus on the dynamic analysis of vibrating screen box has been separated into screen and screen frame.…”

The large-scale and modular design of vibrating screen brings about the trend that the screen separate from screen frame. The separation of the screen frame and the screen changes their dynamic characteristics. By making modal analysis and harmonic response analysis in ANSYS, the dynamic data of the screen and the screen frame was obtained, such as the natural frequencies, mode shapes, stress distribution and strain distribution. The results show that the stiffness of screen frame is higher than stiffness of the screen and the side plats and beams of screen are the weak parts.

“…They have promising application values in the stealth and anti stealth domains. The ultra-wideband antenna [10][11][12][13] is a key component in developing the UWB technique. But it is very difficult to reduce the RCS of the UWB antenna due to the ultra-wide bandwidth.…”

Abstract-As to low observable platform, one of the major contributing sources of target RCS is the scattering due to onboard antennas. So the research on RCS reduction of the antenna is important. In this paper, a holly-leaf-shaped monopole antenna with low RCS is designed. A square notch is etched to improve impedance matching and expand the bandwidth in the ground. The measured −10 dB bandwidth is from 2.1 to 15.4 GHz (only a little higher than −10 dB around 7.5 GHz). The radiation patterns retain symmetry and are relatively stable at 2.5, 8 and 11 GHz. The monostatic RCS performance in four different incident cases is studied to obtain some helpful conclusions for the RCS reduction of the UWB antenna. The RCS achieves effective reduction in comparison with that of the reference antenna. The largest reduction is 4.1, 19.8, 3.9 dBsm in three different incident cases, respectively, while the largest loss of gain is only about −1.3 dB. The antenna suits the occasion of desiring UWB antenna with low RCS.
