WebJun 8, 2024 · The meandering shape reduces the antenna size, and the utilization of the FR-4 substrate does it cost-effective. FR-4 is a cheaper material, readily available, simple to fabricate, and losses are minimal for applications under 1 GHz. The peak gain of 0.145 dBi has been obtained for the designed antenna at the resonating frequency. WebThis yields a meander shape typically present in meandering rivers and has the characteristic that the ratio of meander length to average radius of curvature in the bend is 4.7. Depth, velocity, and slope are shown by field observations to be adjusted so as to decrease the variance of shear and the friction

WebJan 1, 1994 · In the data we analysed the meander wavelength, or twice the distance between successive riffles, is from 7 to 12 times the channel width. It is concluded that the mechanics which may lead to meandering operate in straight channels. River braiding is characterized by channel division around alluvial islands. Webto the meandering shape shown on Fig. 5. Four copper traces of 150 m width ensure the electrical connection between both extremities of the meandering wire. To obtain the traces pattern, a copperclad kapton sheet (Pyralux 18um copper, 25um polyimide) was spin coated (3000 rpm, 30 s) copper side up with photoresist (Shipley SP 24D).
