“…The beam pattern of antenna arrays involving in satellite applications must have low dynamic range ratio (DRR) to minimize the effect of mutual coupling among the elements. However, synthesis of footprint pattern from planar arrays is a challenging task, and several approaches are reported in the literature for obtaining footprint pattern [1][2][3][4][5][6][7][8][9][10][11][12][13][14] with different design specifications.…”

“…The method undertakes the shaping of a desired footprint as a composition of several '-symmetric circular Taylor patterns and the desired footprint is obtained by sampling the obtained circular aperture [6]. Many other methods of generating footprint patterns have been reported in [7][8][9][10][11][12][13][14].…”

An FFT-based footprint pattern synthesis from a rectangular planar array of isotropic antennas by modifying the amplitude, phase and the state ('on'/'off') of the array elements using differential evolution algorithm has been presented. Three different footprints of rectangular, square and circular boundaries are generated from the array while maintaining a satisfactory lower peak sidelobe level and ripple. The method greatly reduces the computational time than the conventional method of calculating beam patterns. The dynamic range ratio of the excitation amplitudes are kept below a threshold level to reduce the design complexity of the attenuators at the feed network level and to minimize the effect of mutual coupling among the array elements.

An improved antenna array pattern synthesis method using fast Fourier transform is proposed, which can be effectively applied to the synthesis of large planar arrays with periodic structure. Theoretical and simulative analyses show that the original FFT method has a low convergence rate and the converged solution can hardly fully meet the requirements of the desired pattern. A scaling factor is introduced to the original method. By choosing a proper value for the scaling factor, the convergence rate can be greatly improved and the final solution is able to fully meet the expectations. Simulation results are given to demonstrate the effectiveness of the proposed algorithm.

It is very intriguing to design passive filters in a very small package, in the frequency domain of 10 GHz and above. Modeling the device footprint and correctly incorporate the model in the design work to design passive filter is key to successfully manufacture surface mount filter components that perform as expected, once they are mounted to the printed circuit board. This requires accurate correlation to the filter model and the measured first article component. In this work we studied footprint and it's influence in the final product. We developed filter design procedure using simulation software. We considered the impact of the parasitic of the input signal lines, printed circuit board's footprint parasitic, and filter's signal launch pad loss. We discussed an efficient way to design low pass passive filters in Ball Grid Array package; we optimized the design flow to manufacture filters. Then we designed and manufactured 12 GHz 9 th order absorptive low pass Bessel filter, whose size is 2.0 mm X 7.1 mm. We compared the measured data of the fabricated filter with the simulation results. We discussed the use of Coaxial Measurement Modules, which contains the filter with optimized design footprint.
