LOOP ANTENNA FOR CIRCULARLY POLARIZED WAVE

摘要

A circularly polarized wave loop antenna can operate in a wide frequency range as well as it can be simply constructed. A radiating power fed to a feeding point (5) via a coaxial line (4) and a feeder conductor (7) is transmitted through an I-shape conductor (2) to a C-type loop element (1). By the action of a cutoff part (6) formed on the C-type loop element, the C-type loop element radiates a circularly polarized wave. An appropriate angle is between 35 DEG and 45 DEG that the I-shape conductor and the cutoff part should form. <IMAGE>
