Abstract

The invention discloses a millimeter-wave air slot differential integrated antenna. The millimeter-wave air slot differential integrated antenna comprises five parts, namely, a differential feeding network, a radiation module, a directed radiation module, a bond wire compensation network and a back cavity air slot; each of the radiation module and the directed radiation module is composed of an even number of radiating patch units which are in bilateral symmetry; signals are divided and transmitted to each radiating patch unit through a differential line and a one-to-many T-shaped structure; the back surface ground part of the antenna is partially etched; an air cavity is formed in a base, so that the bandwidth of the antenna can be extended; the antenna is connected with a chip through bond wires; in order to compensate the inductive effect of the bond wires, a capacitive patch is arranged between the bond wires, so that an L(inductor)-C(capacitor)-L(inductor) network can be formed, and therefore, interconnection loss of the antenna and the chip can be reduced; and in order to extend the bandwidth of the antenna, parasitic patches are arranged beside the radiating patch units. According to the millimeter-wave air slot differential integrated antenna of the invention, a dielectric material of which the height is consistent with the height of the chip is adopted to design the antenna, and therefore, the sticking, bonding and packaging of the antenna and the chip can be benefitted.

Description

technical field

[0001] The invention belongs to the technical field of antennas, and in particular relates to a millimeter-wave air slot differential integrated antenna. Background technique

[0002] Antennas are an integral part of wireless communication systems. The wireless signal is radiated into space through the antenna to realize wireless transmission. With the development of wireless communication systems, the system integration level is getting higher and higher, and higher requirements are put forward for antenna volume, cost and performance. Microstrip antennas have the advantages of low cost and easy integration. However, in the millimeter wave frequency band, the bandwidth of the microstrip antenna often faces certain limitations and needs to be broadened with the help of other technologies. Antenna bandwidth expansion technologies mainly include stacked antenna technology and air slot technology. The stacked antenna technology improves the antenna bandwidth...
