What is The Difference Between a Loop Antenna and a Folded Dipole Antenna?

A loop antenna consists of a closed loop of wire or conductor. When an RF signal passes through the loop, it induces a current in the conductor. This current, in turn, radiates an electromagnetic wave. Compact size, good efficiency at lower frequencies, and can be easily mounted in various orientations. A folded dipole antenna consists of two parallel conductors connected at their ends. One of the conductors is fed, while the other acts as a parasitic element. The parasitic element extends the antenna's effective length and improves its impedance matching to the feedline. Higher input impedance, improved bandwidth, and better efficiency compared to a simple dipole.
