Discover the secret to bending metal effortlessly at home with this ingenious homemade metal bending tool. In this video, we ...

A dipole antenna with a bent dumbbell shape was positioned above and horizontal to a metal reflector to improve peak gain and steering of the radiation pattern. A parasitic square patch etched on the ...

The maximum radiation efficiency can be obtained when the feed array excitation of a reflector antenna is synthesized by the conjugate field matching (CFM) method. However, the CFM method can only get ...
