In view of the low gain and single frequency operation of common microstrip antenna, a novel dual-band microstrip antenna which is fed by microstrip line is proposed in this paper. Using software HFSS to simulate and optimize it, the antenna can work at two bands which are 3.25-3.35GHz and 4.31-4.42GHz.The...

In Direct sequence spread spectrum (DSSS) communication system, the auto-correlation of Pseudo-Noise Code is weak while the auto-correlation of Narrow-Band Interference (NBI) is strong, so that the NBI is more predictable than the DSSS signal. The principle of time-domain anti-interference is the auto-correlation...

The performance of hot rolling steel plates depends on the cooling process after hot rolling. One important point of improving the technology of controlled cooling after rolling is understanding the effect of process parameters. Heat transfer coefficient is a significant physical parameter during the...
