发明名称 Planar antenna with tightly wound folded sections
摘要 A broad-band antenna system capable of receiving VHF, FM, and UHF bands, having highly desirable directional properties, providing sharp nulls for the rejection of unwanted reflections, and with broad directional properties, usually obtainable only with large tunable dipoles or loops, many times the dimensions of this very compact antenna unit. This is strictly a receiving antenna, since it has no radiation capabilities, and consequently minimal loss of received signal due to reradiation.
