Full-wave loop antenna
The full-wave loop antenna consists of a loop elevated from the ground. A circular loop is the most efficient, but squares are also very common because square loops are easier to set up. The full-wave loop antenna has a higher gain than the dipole antenna, but takes up less space when operating at the same frequency.

l is the symbol for length and is measured in meter (m).
f is the frequency in megahertz (MHz).
