Description

Single beam design method based on 1Bit reconfigurable reflection array
Technical Field
The invention belongs to the technical field of antennas, and particularly relates to a single-beam design method which can be used for indoor signal blind-filling and beam scanning of an L-shaped corridor.
Background
With the development of modern communications, there is an increasing demand for functional diversity and adaptability of antennas, especially in radar communications and public communications networks. One of the most important advantages of the reconfigurable reflective array is that beam scanning can be realized, and unlike the conventional phased array which uses complicated T/R components, the required function can be realized by using a low-loss phase converter. The reconfigurable reflective array for realizing beam scanning is the 1Bit reconfigurable reflective array which is applied most. 180-degree phase difference between the units is realized by controlling the PIN tube, so that two states of 0 and 1 are presented, and then compensation phases required by the reflective array units are quantized, so that beam scanning is realized.
Hirokazu Kamoda, Toru Iwasaki et al proposed a 1Bit Reconfigurable reflective array antenna of a millimeter wave imaging system working at 60GHz in an article "60-GHz Electronically configurable Large reflecting Using Single-Bit Phase Shifter" in 2011. According to the design principle, the PIN tube is loaded on a phase delay line at the tail end of a microstrip patch to control on-off, the electrical length of a unit is changed, and therefore the reflection phase of the unit is changed, and finally +/-25-degree beam scanning is achieved. However, when 1-Bit coding is used, two beams of symmetry must occur, which is inherent to 1-Bit itself. Such two symmetric beams are applicable when the application scenario requires exactly two beams, e.g. a T-corridor. However, if only a single beam is required for the reflectarray application scenario, the excess beam is wasted and the main beam is reduced by 3 dB.
Schlemma, Xuxu Shenheng et al proposed a Design of Ku band reconfigurable reflective array unit in 2015 article "Design of a 2-bit reconfigurable reflective array element using two MEMS switches". The design is to load two MEMS switches on one unit to realize 2Bit phase reconfigurability. 1Bit has two states of 0 and 1, and the corresponding phase precision is 180 degrees; however, 2Bit can realize four states of "00", "01", "10" and "11", corresponding to a phase precision of 90 °. Increasing the phase accuracy from 180 ° to 90 ° allows the desired single beam to be obtained, but this increases the cost of the antenna and the complexity of the dc bias circuit.
In summary, there is a contradiction in realizing single beam scanning by the current 1Bit reconfigurable reflective array. A 1Bit would necessarily waste unwanted symmetric beams and would increase the antenna cost if a 2Bit were used.
Disclosure of Invention
The invention aims to provide a single-beam design method based on a 1Bit reconfigurable reflection array aiming at the defects of the prior art so as to obtain an ideal single beam without increasing the cost of an antenna.

the single beam design based on the 1Bit reconfigurable reflection array comprises the following steps:
1) determining the theta scanning range of the main beam of the reconfigurable reflector array as thetaS≤θ≤θ F0 is not more than thetaS＜60,0＜θF≤60；
