Abstract
The invention relates to a method for designing planar phase-control and reflective array antenna. The method for designing planar phase-control and reflective array antenna is characterized in that 1, a conventional array unit one-by-one feed technology is substituted by the air feed technology; 2, a periodical and crystallized EBG (electromagnetic band gap) structure is adopted. Amplitude and phase of each unit excitation in crystal can be valuated optionally, grating lobe can be effectively suppressed, reflective array is more obvious in flexibility than existing phase-control array, and various main electrical parameter are more excellent; and 3, the outline height of the antenna is sharply reduced by adopting a planar circuit board, wherein the period is a variable period. The method integrates the planer reflective array with the phase-control array, so that the outline height of the antenna is greatly reduced and reliability is obviously improved.
Description
Technical field
The present invention relates to a kind of high-gain aerial, relate in particular to the method for designing of the phased reflective array antenna in a kind of plane.
Background technology
Existing high-gain aerial mainly contains two types, and a kind of is array antenna, and another kind is reflector antenna.The plane reflection battle array, situation at home is: because the commercialization process in variety of problems, comprise structural design, reliability design, professional, working ability, accent survey condition etc., develop still slow, the realization commercialization also have a lot of work to do.
Phase array is a kind of of array antenna.From the phase array field, the problem that solve mainly contains: how to remove the feeding network of original complexity, how to improve the reliability of antenna, how to reduce the blind area, how to suppress graing lobe, control secondary lobe etc.
Traditional phase array, each antenna element is wanted independent feed, and for large-scale array, feeding network is very complicated, and debugging is trouble very, and cost also is very high.The independent feed in each unit has caused the reliability of antenna to reduce, and antenna element is very easy to go wrong, and causes the actual sensing of wave beam and expection sensing to greatly differ from each other.The most ancient antenna (unit) diagnostic method is by first method, and antenna element is diagnosed one by one, wastes time and energy.The near field diagnostic method that grows up in the phase at the beginning of the nineties in last century has greatly improved the diagnosis efficiency of array (especially large-scale array).But near field diagnostic method has only provided a kind of efficient diagnostic measures, can not improve from the source reliability of array.
So far there are no take the plane reflection battle array as basic phase array reports.
Summary of the invention
For the problems referred to above, the purpose of this invention is to provide the method for designing of the phased reflective array antenna in a kind of plane.The method can be in conjunction with the advantage of plane reflection battle array and phase array, combines to be the phased array antenna based on the plane reflection battle array.
For achieving the above object, the present invention takes following technical scheme: the method for designing of the phased reflective array antenna in a kind of plane is characterised in that:
1, adopt empty feedback technology to substitute the one by one technology of feed of traditional array element.
2, adopt EBG structure periodic, lattice.To any assignment of the amplitude of each element excitation and phase place, can effectively suppress graing lobe in the lattice, have more obvious flexibility than known phase array, each main electrical parameters is more excellent.
3, adopt planar circuit board, the profile height of antenna is sharply reduced.
The described cycle refers to the variable cycle.
The present invention is owing to taking above technical scheme, it has the following advantages: 1, the present invention applies to phase array to periodicity, lattice technology, suppressed more easily graing lobe, secondary lobe, reduced the blind area, Effective Raise precision and the data transmission bauds of communication system.2, substitute the one by one technology of feed of traditional array element with empty feedback technology, greatly improved the reliability of antenna.3, adopt empty feedback technology, so that at the design initial stage of antenna system, the main classical insulation that accurately calculates (emulation) antenna system becomes possibility.4, the design concept of traditional microwave planar circuit, method, means are introduced Antenna Design, the profile height of antenna is sharply reduced, reliability significantly improves.
Description of drawings
Fig. 1 is the antenna assumption diagram that the present invention designs.
Embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
As shown in Figure 1, the present invention is doing following improvement to the method for designing of antenna:
1, the present invention adopts empty feedback technology to substitute the one by one technology of feed of traditional array element.Adopt empty feedback technology, need not to the independent feed of each antenna element, greatly improve the reliability of antenna.
2, adopt EBG structure periodic, lattice.To any assignment of the amplitude of each element excitation and phase place, can effectively suppress graing lobe in the lattice, have more obvious flexibility than known phase array, each main electrical parameters is more excellent.
3, adopt planar circuit board, the profile height of antenna is sharply reduced.
The described cycle refers to the variable cycle.
