Design and Fabrication of Magnetic Loop Antenna for 5MHz

In the short-wave range, size of antenna become large and therefore is a major constraint. Magnetic Loop Antenna provides an advantage over other antennas in terms smaller size, higher quality factor better signal to noise ratio. It works on principle resonance with inductor provided by loop external tuning capacitor operating like tank circuit. The tunable magnetic designed work high frequency range. consists circular hollow copper pipe, inductive feed variable capacitor. tuned using 9-140pF paralleled 150pF simulated 4NEC2 software. has efficiency more than 1000. real time testing show great result at 5.45MHz bandwidth 8KHz.
