The proposed method is based on the generalized-scattering matrix and spherical wave expansion analysis of the array. Mutual coupling effects between radiating elements are inherently considered in the design process. A linearly polarized 24-element irregular slotted array antenna at Ku-band is presented to describe the proposed computer automated design methodology. A prototype has been manufactured to experimentally validate the antenna performance. At the design frequency (17 GHz), 15.9 dB realized gain and 97\% efficiency (excluding aluminum losses) values are achieved. Although the array is designed at a single frequency, it shows an overall experimental 7\% usable bandwidth.}, keywords = {Array antenna, computer automated design, generalized scattering matrix, slot, spherical wave expansion}, issn = {1536-1225}, doi = {10.1109/LAWP.2016.2517928}, url = {http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=\&arnumber=7381600}, author = {J C{\'o}rcoles and P Sanchez-Olivares and J Rubio and J L Masa-Campos and J.

The single radiator consists of four cross tilted slots. In addition, a pair of tuning metallic vias is included to improve the reflection of longest slots. A 16-element antenna prototype with -26-dB Taylor distribution and 1.5\% residual power was designed, manufactured and measured to verify the new slot performance in an array configuration. A 17-dB peak gain, 1.86-dB axial ratio and 80\% radiation efficiency were experimentally achieved at 17 GHz. A 3\% usable bandwidth was obtained owing to frequency main beam tilt dispersion.}, keywords = {16-element antenna prototype, antenna, Antenna measurements, antenna radiation patterns, array configuration, Arrays, circular polarization (CP), circularly polarized element, circularly polarized linear array, Couplings, four cross slot radiator, four cross tilted slots, frequency 17 GHz, frequency main beam tilt dispersion, linear antenna arrays, linear array, metallic vias, microwave antenna arrays, radiation efficiency, Reflection, single radiator, SIW linear array, slot, slot antenna arrays, substrate integrated waveguide, substrate integrated waveguide (SIW), substrate integrated waveguides, Substrates, Taylor distribution, Tuning, tuning via, tuning vias}, issn = {0018-926X}, doi = {10.1109/TAP.2014.2299823}, url = {http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=\&arnumber=6710164}, author = {P Sanchez-Olivares and J L Masa-Campos} }
