This work presents the design of a compact dual-port circularly polarized antenna based on the new coupler topology. The antenna can radiate a right-hand circular polarization (RHCP) in two opposite directions depending on the input port. In the proposed structure. the radiating system has three inverted F antennas connected to a 120° hybrid coupler. https://www.marcelovicente.com/product-category/cuticle-enhancing-lotion/
