The present application adopts a loop antenna wiring form, which increases the performance while also meeting the problem of too small wiring area. The loop antenna has a small volume due to its folding, is suitable for large-diameter and super-large-diameter antennas, and has become the focus of research and application at home and abroad. The terminal load impedance of the loop antenna can be zero or equal to the characteristic impedance of the loop, and the current distribution thereon is similar to that of a parallel transmission line. The current on the electrically small loop is approximately distributed in equal amplitude and in phase. The current on the electrically large loop is a standing wave distribution. When the impedance of the terminal load is equal to the characteristic impedance of the loop, the current on the loop is a traveling wave distribution. According to the principle of electromagnetic radiation duality, the radiation field of the electrically small loop and the small electric dipole antenna placed perpendicular to the loop surface is similar except that the electric and magnetic quantities are interchanged, i.e. the pattern in the plane of the loop face is far, the pattern in the plane of the loop axis is eight-shaped, and the radiation along the loop axis is zero.
