A loop antenna may include first and second electrical conductors arranged to define a circular shape with first and second spaced apart gaps therein. Opposing portions of the first and second electrical conductors at the first gap may define a signal feedpoint, and opposing portions of the first and second electrical conductors at the second gap may define an impedance tuning feature. The second gap may be circumferentially spaced from the first gap less than ninety degrees, and the second gap may be greater than the first gap to provide a predetermined impedance. A coaxial transmission line may form a feed inset into the loop conductor. The loop antenna may be planar and have a reduced size for ease of manufacture and use, and it may provide an isotropic radiating pattern at a predetermined operating frequency, which may avoid the need for antenna aiming.
