As a consequence of the radiation pattern requirements, the proposed antenna consists of a conical skirt monopole with a polarizer radome. The polarizer converts a wave from linear to circular polarization. The proposed antenna has the advantage to be robust, low cost, and easy to fabricate with conventional materials and printed circuit technology. The study presents simulation and experimental results obtained with an antenna prototype that validate the design.}, keywords = {arrival signal direction detection system, Circular polarization, millimeter antenna, omnidirectional antenna}, issn = {0895-2477}, doi = {10.1002/mop.22237}, url = {http://onlinelibrary.wiley.com/doi/10.1002/mop.22237/abstract}, author = {Fern{\'a}ndez, J M and J L Masa-Campos and Sierra-P{\'e}rez, M} } @article {3_CouplingJMOEA, title = {Coupling Characterization and Compensation Model for Antenna Arrays}, journal = {Journal of Microwaves, Optoelectronics and Electromagnetic Applications}, volume = {4}, number = {2}, year = {2005}, month = {Dec.}, pages = {95-110}, abstract = {Coupling is an important aspect to be considered in the design process of antenna arrays. The real feeding radiated coefficients can be quite different from the theoretical ones because of this effect. In this paper, a characterization and compensation model is presented. This procedure is capable of matching each element of the array. All the parameters of the array coupling model are obtained through the measurement of scattering parameters and radiation patterns of the individual elements. Some practical applications to linear patch arrays are presented.}, issn = {1516-7399}, url = {http://www.jmoe.org/site-number?id=3}, author = {J L Masa-Campos and Fern{\'a}ndez, J M and Sierra-Casta{\~n}er, M and Sierra-P{\'e}rez, M} }
