Dual-Beam Tensor Impedance Modulation Antenna

In this paper, we designed a dual-beam tensor impedance surface antenna with dual feed sources. The basic principles of tensor impedance modulation were introduced, and based on these principles, the unit structure and array arrangement were designed. When the two feed sources operate independently, they radiate ±45° polarized beams, respectively. Finally, a prototype antenna was fabricated and tested, with the test results showing good agreement with the simulations.
