Abstract

The invention discloses a half-wave dipole array element and a micro-strip array antenna formed by the half-wave dipole array element. The array element comprises a copper-coated substrate, wherein two half-wave dipoles are arranged on the substrate; impedance matching holes and impedance matching slots are arranged in the front surfaces of the half-wave dipoles; transmission micro-strip lines are arranged on the back surfaces of the half-wave dipoles; and the upper ends of the transmission micro-strip lines are connected with the impedance matching slots after passing through the impedance matching holes, and the lower ends of the transmission micro-strip lines are connected with feed interfaces and matching resistors. According to the scheme, the coalition of sampled signals of the antenna are completed through a processor, the amplitudes and phase positions of micro-strip elements in multiple micro-strip arrays are regulated by utilizing a digital signal processing technology, a needed directional diagram is formed in space, and a mechanical rotating system is no longer needed.

Description

technical field [0001] The invention relates to a radio wave receiving device, in particular to an antenna. Background technique [0002] An antenna (antenna) is a transformer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas. Generally, antennas are 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 transmit...
