@article {13_AWPL_GARCIA-VALVERDE_PFC, title = {Linear Patch Array Over Substrate Integrated Waveguide for Ku-Band}, journal = {IEEE Antennas and Wireless Propagation Letters}, volume = {12}, year = {2013}, pages = {257-260}, abstract = {A linearly polarized patch array with direct probe feed over substrate integrated waveguide (SIW) network (LP-PASIW) for Ku-band is presented. A double-stacked microstrip patch structure has been used as radiating elements. Internal SIW coupling patches are placed inside the SIW to obtain the desired radiation pattern. The internal coupling and external radiating patches are connected by means of copper vias. A mutual coupling model is also proposed to adjust the radiation and reflection properties of the array. An antenna prototype has been manufactured and measured. At 17.7 GHz, 16 dBi and 80\% peak gain and efficiency values are obtained. Although a 10\% reflection bandwidth (17-18.6 GHz) is achieved, the usable bandwidth is reduced to 3\% due to array beam tilt dispersion.}, keywords = {antenna feeds, antenna prototype, antenna radiation patterns, Antennas, array beam tilt dispersion, Arrays, bandwidth 17 GHz to 18.6 GHz, Brain modeling, Couplings, direct probe feed, double-stacked microstrip patch structure, Double-stacked patch, efficiency 80 percent, electromagnetic wave polarisation, external radiating patches, frequency 17.7 GHz, hybrid LSM$^{{rm y}{\textquoteright}}$ mode, internal coupling patches, internal SIW coupling patches, linearly polarized patch array, LP-PASIW, microstrip antenna arrays, microwave antenna arrays, Mutual coupling, mutual coupling model, radiating elements, radiation pattern, Reflection, substrate integrated waveguide (SIW), substrate integrated waveguide network, substrate integrated waveguides, Substrates, waveguide antenna arrays}, issn = {1536-1225}, doi = {10.1109/LAWP.2013.2245623}, url = {http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=\&arnumber=6451111\&tag=1}, author = {D Garcia-Valverde and J L Masa-Campos and P Sanchez-Olivares and B Taha-Ahmed and J C{\'o}rcoles} } @conference {APS-URSI-2013, title = {SIW patch array with internal coupling patches}, booktitle = {Antennas and Propagation Society International Symposium (APSURSI), 2013 IEEE}, year = {2013}, month = {July}, pages = {1800-1801}, abstract = {A Substrate Integrated Waveguide (SIW) has been used to feed a progressive wave linear array of 16 double stacked patches.
