摘要：
In this article, we present a composite feed dual circularly polarized (CP) aperture-coupled microstrip antenna at L-band with improved characteristics. Two dedicated feeds have been conceived; one feed produces left hand CP, while the other generates right hand CP (RHCP). A prototype has been designed, fabricated and experimentally measured. 7.8% axial ratio bandwidth at each of the ports and in-band interport isolation over 18 dB without using power divider has been demonstrated. As much as 3.5 dBi gain at each port have been achieved experimentally. (c) 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:283-289, 2016
