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} }
