A phase-only diffractive optical element (DOE) for generating array of optical vortices with high compression ratio is presented. Since it is designed according to the fractional Talbot effect, we name the DOE optical vortex Talbot array illuminator (OVTAI). As an example, an OVTAI for generating a
## Abstract Based on the conventional microstrip antenna, a broadband circularly polarized microstrip antenna fed by electromagnetism coupling is designed, which is composed of three substrates. The frequency band is broadened not only, but also the circular polarization axial ratio is effectively
