摘要
In this paper, a CTS (continuous transverse stub) antenna array using SIW (substrate integrated waveguide) technology is proposed. The antenna consists of quasi-TEM wave generator, E-plane corporate feeding network and radiation slots. The pillbox structure is used to generate quasi-TEM wave in the oversized rectangular waveguide. Then the energy is divided by E-plane corporate feeding network and fed the radiation slots. From the simulated results, it can be seen that the reflection coefficient is below -10 dB from 22GHz to 28GHz, and gain is about 24.3dBi at 25GHz with the efficiency of 59%.
