Problems solved by technology

When multi-angle feeding is required, multiple ports need to be added; however, even if multiple ports can be added to achieve multi-angle beam scanning, there will still be some angles that cannot be scanned, so angular continuous scanning cannot be achieved

Abstract

The invention discloses an integrated lens antenna, which comprises a first dielectric lens, a microstrip radiation unit and a base, the microstrip radiation unit is arranged at one side of the base and located in the base; the first dielectric lens is of a rotational symmetry structure, and a main body of the first dielectric lens is hemispherical; the plane side of the first dielectric lens is arranged at the other side, far away from the micro-strip radiation unit, of the base, and is spaced from the micro-strip radiation unit; therefore, a certain height difference exists between the hemispherical dielectric lens and the microstrip radiation unit, the influence of the dielectric lens on the impedance matching performance of the microstrip radiation unit is reduced, and the hemispherical rotational symmetric structure can convert the radiation beam of the microstrip radiation unit into a parallel beam; therefore, the radiation beam can realize continuous scanning in the two-dimensional direction and can be converged, the gain of the lens antenna is improved, and the continuous scanning in the two-dimensional direction of the antenna is realized.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an integrated lens antenna and communication equipment. Background technique [0002] The lens antenna is an antenna capable of changing the beam plane of the passing electromagnetic wave, and it is widely used in various wireless communication systems. [0003] At present, integrated lens antennas usually use multi-port feeds to realize beam scanning, that is, one port feeds to realize beam radiation at one angle. When multi-angle feeding is required, multiple ports need to be added; however, even if multiple ports can be added to achieve multi-angle beam scanning, there will still be some angles that cannot be scanned, so angular continuous scanning cannot be achieved. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an integrated lens antenna to realize continuous scanning in the two-dimensional direction of the antenna. ...
