摘要： A 5 dBi embedded dual-band WiFi circular polarized 50 mm patch antenna with an SMA(f) connector is described. The antenna features a high efficiency dual-band WiFi 2.4 GHz/5˜6 GHz right hand circular polarization (RHCP). The antennas improve upon the previously developed antennas by simplifying the construction and simplifying the feed, while retaining circular polarization across two widely-separated bands. In order to integrate prior antennas into a system with simple coaxial connections, additional components and devices were required. The antennas simplifies the integration whilst retaining the circular polarization and dual frequency operation. The ratio between the two frequency bands can be adjusted by changing the middle patch and the V-shaped slot size of the top layer. The V-shaped slots improve the axial ratio bandwidth and assist with setting the frequency ration between the two bands.
