Abstract
A novel type of T-type Power Divider feed network is designed for the difficulty of meeting the needs of both the broadband and miniaturized applications of the existing circularly polarized antenna. At the center frequency, the input signal is transmitted through the active shift phase feed network, and the four-way signal is equitized at its output port, with a phase lag of 90° in turn. It is worth noting that the T-type node does not have an isolation resistor, so the matching and isolation of the output port is not considered. The test results list the echo loss of the internal functional feed network Input port, the insertion loss of the circuit, and the phase difference between the output ports. The network theory is applied in the antenna feed network, which can improve the performance of the antenna and is suitable for long-distance highly directional reading and writing applications.
