摘要
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 degrees hybrid coupler. The modeling and design of the 5-ports hybrid coupler are described and experimentally validated. The antenna prototype is fabricated using two 1.6mmthick low-cost FR4 Epoxy substrates assembled with metal wires, with a dimension of 80mm x 80mm x 12mm (ka < 0.74). The proposed antenna provides the realized RHCP gain of 2.4 dBic and 1.8dBic at 868 MHz for Port 1 and Port 2, respectively.
