@conference{10902/7626, year = {2015}, month = {9}, url = {http://hdl.handle.net/10902/7626}, abstract = {This paper presents a novel feeding system for obtaining circular polarized microstrip antennas, which is based on electromagnetic coupling in a single layer. The proposed circularly-polarized (CP) operation can be achieved simply by lengthening a microstrip line in the feeding system, without modifying the microstrip radiator. From the experimental results, the 3-dB axial-ratio bandwidth can reach as large as 98 MHz (3.9% relative to the center frequency of 2.44MHz) for the application as a 2.45-GHz RFID reader, or communication in ISM band.}, publisher = {URSI 2015, XXX Simposium Nacional de la Unión Científica Internacional de Radio, Pamplona}, title = {Generación de campo polarizado circularmente en geometría plana con alimentación asimétrica}, author = {Torres García, Alicia E. and Marante Rizo, Francisco Reinerio and Tazón Puente, Antonio and Vassallo Sanz, Juan}, }
