Methodology as set of theoretical and practical methods, such as material modeling and experiment, at the choice of rational decisions the developer, are used in the course of development of an antenna lattice.

For the choice of type of antennas the trial and error method on compliance of technical characteristics and parameters of the antenna to conditions of their work is presented to designs of a subject to placement as the specifics of orientation of developments of the antennas connected with the principle of operation of the radio equipment served by them make special demands to the antennas installed on aircraft of radio engineering, mechanical and temperature character.

The EW modern equipment has to have the high speed of reception and information transfer, broad band of transmission on radio signal frequency, noise immunity, to work at the same time in wide frequency range, to be inexpensive in production and operation.  The broad band of transmission on radio signal frequency is reached due to use of modern types of antennas which bandwidth can be tens of gigahertzes.

The main type of the antenna used in the equipment with a working strip of frequencies in several gigahertz is printing antennas. At researches and modeling with double polarization for application in antenna lattices of the EW aircraft equipment for performance of tasks in frequency range 4…18 GHz the microstrip slot-hole antenna known as Vivaldi's antenna is chosen as subject to development of the broadband antenna. 

Researches of development were conducted in the program CST Studio Suite environment which allows to make modeling of characteristics of radiation of the antenna.

As a result of modeling Vivaldi's antenna with a linear the extending part unlike step, exponential and Klopfestena allowing to receive the combined orthogonal design of double polarization in the minimum dimensions of the antenna without loss of quality of characteristics and parameters of the single radiator is chosen. 

Completion of each of orthogonally the located antennas on shift of the feeding part for an exception of their crossing when crossing a design is carried out.

Having opened and thickness of a substrate of antennas calculated taking into account an exception of short circuit of area of an exit of the resonator of a collected orthogonal design and maintaining characteristics and parameters of antennas in the necessary limits.  Work modeling orthogonally of the located Vivaldi's antennas (double polarization) as a part of an antenna lattice 4×4 is carried out.  Results of researches of an antenna lattice with double polarization antenna element show that the developed design after insignificant completions can be applied in the EW aircraft equipment as a part of onboard complexes of defense of planes to creation of a coherent hindrance and violation of working capacity radar Station with circular polarization.
