Abstract

The invention discloses a planar antenna for a dual-frequency millimeter wave system. The planar antenna for the dual-frequency millimeter wave system comprises a radiation plate printed at the middle of a medium plate and used for emitting or receiving electromagnetic wave energy, a symmetrical E-shaped groove arranged at the middle of the radiation plate and used for providing a current path needed for dual-frequency resonance, feed structures arranged at two sides of the radiation plate and used for providing signal feed for the radiation plate, a grounding plate arranged on the lower surface of the medium plate and used for providing grounding signals, and an antenna port arranged in the lower surface of the medium plate and used for inputting differential signals to the feed structures. The planar antenna for the dual-frequency millimeter wave system is simple in structure and convenient to popularize in millimeter wave antennas, and the directional diagram height is symmetrical at the millimeter wave frequency band.

Description

technical field [0001] The invention relates to a communication antenna, which belongs to the technical field of millimeter wave communication antennas, and in particular to a planar differential antenna with a single-layer PCB structure and a differential CPW feed that can be simultaneously applied to two frequency bands in a dual-frequency millimeter wave system. Background technique [0002] At present, most of the spectrum in the middle and low frequency bands in the communication field has been occupied by civilian or military planning, and the current spectrum resources have become very precious. However, people's requirements for various data transmission rates are getting higher and higher, so the contradiction between supply and demand of spectrum resources is becoming more and more prominent. Therefore, more and more researchers are devoting research and development energy to millimeter wave technology. It can effectively alleviate the contradiction between supply ...
