In this paper, we propose a novel radial line planar phased array in which helical antenna elements are individually rotated by their respective connected micromotors to realize dynamic beam-scanning.
With LISA, ESA plans to catch gravitational waves from space, using a triangle of spacecraft millions of kilometers apart—unlocking cosmic secrets we’ve never seen.
The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on balloons high above Antarctica that are designed to detect ...
The low-profile hemispherical helical antenna is studied experimentally and theoretically. This antenna can produce circular polarization radiation over a wide angular range of 90/spl deg/. The ...
