Abstract
A reflect cluster receiving wire (RAA) with a wideband high-power double branch helical reflect cluster is demonstrated. Two metal helical branches make up the reflecting component, and the movable pivot points allow for full 360o stage rotation. A 9 X 9 rectangular cross section X-band RAA model is imitated and estimated. The best get of 23.7 dB is achieved with the bar concentrated at (=20,=0) course at focus repeat of 9.3 GHz, and the 1-dB get a move on is more than 24.2%, according to full-wave reenactments. In the entire band, the intentional reflection coefficient is not exactly - 16.3 dB. The endeavored significant rate is under 2.3 dB from 8.4 GHz to 10.8 GHz. The attempted get at center rehash is 23.4 dB, and the differentiating opening helpfulness is 50.6%. The RAA's bar inspecting execution is endeavored inside 30o exactness in two balanced planes with a check trouble of under 1.5 dB and focus point degrees of under 1.4 dB. Under vacuum, the mirrored results provide the appearance that the RAA's force taking care of limit is approximately 358 MW.
