Abstract

The invention discloses a double-loop antenna, relates to the technical field of antennas and aims to solve the problems of larger size or lower measurement precision and lower direction finding efficiency of conventional direction-finding antennas. The double-loop antenna comprises a first antenna loop body and a second antenna loop body which have the same structure and electrical performance, wherein the first antenna loop body and the second antenna loop body are in nested connection, and the first antenna loop body is perpendicularly and coaxially arranged with the second antenna loop body. The invention is mainly applied to manufacture of the direction-finding antennas.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a double-loop antenna. Background technique [0002] An antenna is a component used to transmit or receive electromagnetic waves in a radio device; the antenna can transform the guided wave propagating on the transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. Moreover, antennas are generally reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna; the basic characteristic parameters of the same antenna as a transmitting antenna or a receiving antenna are the same.
