A substrate integrated slot array antenna with a prescribed radiation pattern is investigated in this paper. To meet the requirement of a certain standard radiation pattern envelope, the array configuration and the element excitation coefficient should be considered together. An efficient and systematic method is proposed to determine the element number and element weights in a planar array. After that, the geometrical dimension of the substrate integrated slot array can be synthesized. As an example, aK-band 16 × 22 slot array antenna based on the substrate integrated waveguide (SIW) technology is designed, fabricated, and measured. Its radiation pattern can meet the class 3 antenna radiation pattern envelope of the European Telecommunications Standards Institute (ETSI) standard pattern. Experimental results are in good agreement with simulated ones.

Assess the array element number of planar phased array antenna which suffers fragments combat damage. A single fragment damage as the research object, the simulation of penetration condition for Tungsten Spherical fragments is developed using the software of ANSYS/LS-DYNA. The penetration of antenna at 0°attack angel and 800m/s is simulated, and we can gain the penetrated distortion data. Based on the data the damage circular is calculated. The last one study was made on x-band planar array antennas, the array elements invulnerability of triangular setting is better than rectangular, and the influence characteristics between the position of the damage circle and the damage of the antenna. The results can be used in a rapid assessment of a battle-damaged Radar repair and maintain inventory of phased-Array element.

Abstract This paper suggests a cylindrical configuration for agile beam polarimetric phased-array radar (PPAR) for weather surveillance. The most often used array configuration for PAR is a planar array antenna. The planar configuration, however, has significant deficiencies for polarimetric measurements, as well as other limitations, such as increases in beamwidth, decreases of sensitivity, and changes in the polarization basis when the beam scans off its broadside. The cylindrical polarimetric phased-array radar (CPPAR) is proposed to avoid these deficiencies. The CPPAR principle and potential performance are demonstrated through theoretical analysis and simulation. It is shown that the CPPAR has the advantage of a scan-invariant polarization basis, and thus avoids the inherent limitations of the planar PPAR (i.e., PPPAR).
