Description
Technical Field
The invention relates to the technical field of patch antennas, in particular to a closely-arranged low-mutual-coupling patch antenna.
Background
The patch antenna has the advantages of simple structure, small plane size, mature manufacturing process and the like, and is widely applied to microwave and millimeter wave frequency bands. When a plurality of patch antennas form the multi-unit patch antenna array, the channel capacity and the signal transmission reliability can be improved, and the efficient utilization of frequency spectrum resources is facilitated. Meanwhile, the overall size of the multi-unit patch antenna array is determined by the space between the patch antenna units, and the multi-unit patch antenna array which is tightly arranged is beneficial to the miniaturization of wireless equipment. However, mutual coupling between antenna elements usually deteriorates as the spacing between the elements decreases, resulting in deterioration of radiation performance of the antenna array and system channel capacity. Therefore, there is a need for a closely packed low mutual coupling patch antenna.
The existing mutual coupling removing technology of patch antenna mostly corresponds to the unit edge distance of 0.1-0.3 lambda 0 (λ 0 Free space wavelength corresponding to center frequency) when the cell pitch is further reduced to close alignment (< 0.05 λ 0 ) And the decoupling function fails to work due to the reasons of failure, too large size and incapability of placement and the like. There are three methods that can be applied to the close-packed patch antenna decoupling. The first is to add an electromagnetic band gap periodic structure in a coplanar manner around the patch antenna unit or add a super surface periodic structure on the upper layer. The second is to load lumped inductive elements across the patch antenna elements. The third is to combine and superimpose an additional decoupling network in the feed network. All three of the above methods require additional antenna parasitic structures, elements or networks, which complicate the antenna structure, increase size, limit operating frequency, or increase loss.

In the embodiment of the present invention, the conductive structures 6 are all metal through holes, which are commonly used in the art and are not described herein again.
When the antenna is used, when a signal is fed into the first main radiating element 21 and the second main radiating element 22 is connected with a matched load, the signal is fed through the metal probe 7 of the first main radiating element 21 to excite the first main radiating element 21 and excite the first secondary radiating element 31 through the three conductive structures 6 to form radiation of the element 1; while radiating, the cell 1 is coupled through two paths: the path 1 is a first main radiating element 21 of the unit 1 to a second main radiating element 22 of the unit 2; the path 2 is from the first secondary radiating element 31 of the unit 1 to the second secondary radiating element 32 of the unit 2, and a part of signals are superposed on the unit 2 to form mutual coupling, and the weaker the mutual coupling, the smaller the radiation influence on the unit 2 per se is.
The procedure is the same as described above when the unit 2 is fed with a signal and the unit 1 is loaded.
In the invention, two patch antenna units work in quasi-TM 01 In the mode, an electric field between the metal patch and the metal ground 5 presents half-wave distribution along the polarization direction, and the polarization component intensities of the electric fields on the two sides are close. On the connecting line surface of the three conductive structures 6, the electric field is uniformly distributed in the same direction. And horizontal electric field distribution in opposite directions exists at the E-surface feeding position of the patch antenna, and a coaxial electric field at the feeding position is converted into a patch electric field to finish feeding and impedance matching. The connecting lines of the three conductive structures 6 are used as boundaries, the electric field of the main radiation unit 2 is mainly concentrated in the two layers of dielectric substrates, and the electric field of the secondary radiation unit 3 is mainly concentrated in the second dielectric substrate 4, so that different equivalent ground capacitances are formed on two sides of the polarization direction of the antenna. The different equivalent capacitance to ground causes the polarized electric field components on both sides to have different initial phases. Meanwhile, under the condition of close arrangement, the coupling between the two main radiating elements 2 of the two elements and the coupling between the two secondary radiating elements 3 have different coupling phases. Finally, the different polarization electric field initial phase differences and the coupling phase differences of different coupling parts are superposed to form the offset effect of two coupling paths, so that a mutual coupling zero point can be formed in the working frequency band, and the coupling of the whole working frequency band is reduced.
The position of the mutual coupling zero point can be controlled by controlling the height of the conductive structure 6, namely the distance between the main radiating unit 2 and the secondary radiating unit 3 and the position of the conductive structure 6, and the central frequency can be controlled by controlling the lengths of the main radiating unit 2 and the secondary radiating unit 3 along the polarization direction.
