Compared to radio frequency communication, optical communication can maintain higher transmission rates and more reliable channel modes. However, there are also some issues with optical communication technology, such as line-of-sight issues, where optical communication cannot proceed normally when there are obstacles between the sending and receiving ends. A photoelectric integrated antenna has been designed to address the above issues, which can simultaneously perform millimeter wave communication and optical communication. When optical communication cannot function properly, the millimeter wave antenna can work, thus compensating for the line-of-sight defect in optical communication. The main material used in the design is K9 glass. By utilizing the different physical properties of K9 glass in different frequency bands, designing appropriate lens shapes and scaling the lenses, K9 glass can achieve different forms of communication work in the millimeter wave communication frequency band and optical communication frequency band. When K9 glass is used as a dielectric resonator, millimeter wave communication is achieved; When used as a lens, it can focus the light beam and achieve optical communication. The millimeter wave antenna is fed by a coplanar waveguide, and a patch type LED light source is placed below the center of the dielectric resonator through slotting technology. This optoelectronic integrated antenna integrates the optical wave communication system and the millimeter wave communication system on a single metal aluminum plate, enabling two types of communication simultaneously without interfering with each other. The simulation results show that the operating frequency of the millimeter wave antenna is between 32.5GHz and 33.4GHz, and the gain within the frequency band is stable. The peak gain of a single dielectric resonator can reach 5.4dBi. After adding the lens, the optical power at the receiving end is significantly increased, thereby improving the transmission rate of optical communication.
