“…The interval prediction (Equation (33)) was validated through 1000 sets of simulations on the whole array antenna. Simulation results show that the variation range of the power pattern based on Equations (17) and (30) was very accurate, and the experimental results showed that 996 results of 1000 total experiments satisfied the predicted fluctuation interval, as shown in Figure 9. The flatness of the reflection plate was discretized to 6 specific values, that is:…”

“…Note that the x and y directional position error was ignored, because they can hardly affect the main beam and the first side lobe [15], which reflects the performance of the antenna, and details of this can be found in Appendix A. The influences of x and y directional position errors were ignored, and several researchers have also adopted this approximation [2,15,17]. The horns were bolted to the reflection plate, the position (especially the z directional position) of the horn elements is affected by the manufacture error and assembly deformation, as shown in Figure 4.…”

With the increase of the working frequency of the array antenna, tolerance design has become increasingly important. The state-of-art tolerance design methods mainly deal with the position tolerance of the discrete elements. However, the geometric errors of the whole array have resulted from two aspects: (1) the position errors of the discrete elements and (2) the form errors of the continuous reflection plate. To optimize the position tolerance and flatness simultaneously, a hybrid tolerance design method is proposed. First, the relation between the performance of the array antenna and hybrid tolerances was determined based on the second order Taylor expansion. Then the expectation and variance of the performance were derived. Finally, the hybrid tolerances were optimized and the performance of the antenna was improved. Simulation results proved the effectiveness and efficiency of the proposed hybrid tolerance design method.

“…Aircraft flight regimes often limit the size of antenna apertures, and creating structures that are aerodynamically and structurally efficient while also satisfying electrical requirements is often difficult. In addition, structural deformations, airframe material, and vibrations have all been shown to affect antenna performance [4][5][6][7][8][9].…”

Structurally integrated antenna arrays provide synergies allowing the integration of large apertures onto airborne platforms. However, the surrounding airframe can greatly impact the performance of the antenna array. This paper presents a sensor-driven preliminary wing ground plane sizing approach to provide insight into the implications of design decisions on payload performance. The improvement of a wing-integrated antenna array that utilizes the wing as a ground plane motivated this study. Relationships for wing span, wing chord, and thickness are derived from extensive parametric electromagnetic simulations based on optimum antenna performance. It is expected that these equations would be used after an initial wing-loading design point has been selected to provide the designer guidance into how various wing parameters might affect the integrated antenna performance.

The microwave antennas mentioned in this paper include microwave reflector antenna, plate slot-array antenna and active phased array antenna, in which the fields of electromagnetic, structural deformation and temperature interrelate or interact with each other. This interrelationship is, in this manuscript, called the multi-field coupling problem of microwave antenna. To design microwave antenna with high performance, it is significant to establish the field-coupling model and understand the coupled mechanism of these three fields radically. This thesis aims to illuminate the solution strategies and methods of field-coupling theoretical model, based on which, the multidisciplinary optimization model will be set up.
