Problems solved by technology

The unit arrangement determines the phase control accuracy. If the unit arrangement is too dense, the coupling between units will increase accordingly. If the arrangement is too sparse, the phase control accuracy will be low.

Embodiment Construction

[0015] like figure 1 As shown, the array of the pattern-programmable metamaterial array antenna is composed of a single radiating element. The radiating patch is located on the top of the feeding waveguide slot. There is a metamaterial layer between the waveguide slot and the radiating patch. The electromagnetic wave excites the radiating patch through the slot. The radiation patch radiates electromagnetic waves to the space. By precisely adjusting the amplitude and phase of the elements in the array, the electromagnetic waves are superimposed in space to form the desired beam.

[0016] like figure 2 As shown, the present invention provides an embodiment of the pattern programmable metamaterial array antenna element arrangement is an equilateral triangle array arrangement, the equilateral triangle array arrangement includes the arrangement shape and element spacing, and the element distribution At the three vertices of an equilateral triangle, the spacing between each unit i...

Abstract

The invention provides a design method of a directional diagram programmable metamaterial antenna array. The antenna array is composed of single radiation units, a radiation patch is located at the top of a feed waveguide slot, a metamaterial layer is arranged between the waveguide slot and the radiation patch, electromagnetic waves excite the radiation patch through the slot, and the radiation patch radiates the electromagnetic waves to the space; by accurately regulating and controlling the amplitudes and phases of the units in the array, electromagnetic waves are overlapped in space to form a required directional beam, the invention provides an arrangement mode of the directional diagram programmable metamaterial array antenna units, and the arrangement mode of the array units comprises equilateral triangle array arrangement, rectangular array arrangement and annular array arrangement; each arrangement mode can control the antenna array directional diagram through a corresponding algorithm.

Description

technical field [0001] The invention relates to the technical field of metamaterial array antennas, in particular to a method for designing a pattern-programmable metamaterial antenna array. Background technique [0002] The antenna is an important component for sending and receiving electromagnetic wave energy in wireless transmission, allowing users to smoothly use the wireless communication system for information transmission without being restricted by terrain. At present, antennas used in various products have different design methods and materials. Choosing an appropriate antenna can help improve transmission characteristics and reduce production costs. [0003] The spacing between phased array antennas is affected by the scanning angle. The purpose of spacing design is to control the array sidelobe level, and the spacing between antenna elements will decrease appropriately as the scanning angle increases. [0004] The pattern-programmable metamaterial array antenna ...
