This paper is focused on the acquisition of the edges of metal rectangle in the field of aluminum industry with high accuracy. The image of the metal rectangle has the reflection interference, which is not easy to get rid of in image processing. In this paper, the raw edge is acquired by gray level difference. Then, the fine edge is acquired by abandoning the noisy data. In the end, Least Square Method...
A spot-focusing metal plate lens antenna used in high-temperature measurement is designed, it consists of a conical horn, several metal plates and a water-cooling metallic sheath. Good performance of standing-wave ratio (SWR), gain and focusing action at 10GHz is obtained. The focal length and 3-dB beam width in the E-plane and H-plane are measured because of the need of near field measurement, a...
In this paper, a novel microstrip patch antenna is proposed which has Zeroth Order Resonance (ZOR) mode and is based on the Composite Right and Left Handed (CRLH) structure. The metallic patch is suggested to be coupled with four surrounding unit cells. It is different from the previous 1D ZOR antennas commonly having several metal cells in line or the conventional ZOR antennas of periodic mushrooms...
