WebI. Introduction Traditionally, reflector antennas are designed for limited scan. A symmetrical parabolic reflector with fD4.4 can only scan d5 beamwidths (BW) with less than 2 dB loss [ 13.If the reflector diameter is 1,0oO h, the f5 BW scan corresponds to only &OS0, which is a very narrow field of view. In some future applications, the antenna requirements will be … Web25 de mai. de 2024 · 111. SLK001 said: Putting a reflector behind your antenna will only work if the frequencies are interger multiples of each other. If so, then use the half-wavelength of the lowest frequency. Other than that, you might need to simulate your design to see the effect of the reflector position on each frequency. thnak u for ur reply. Web29 de dez. de 2015 · Reflector antennas have various types and designs, among which parabolic reflectors are the most commonly used in practice. By selecting proper geometrical parameters and feed illumination, the reflector radiation characteristics such as gain, beamwidth, sidelobe level, and cross-polarization can be well tailored for different goals. how does a rotor and stator work
