Design of sector antenna with wideband 2D hat-fed reflector for wireless communications

We present the design of a new sector reflector antenna with 2-dimensional hat feed in order to avoid the radio link disconnection in point-to-point link communication systems due to the swinging of link antennas when there is a strong wind or vibration. The antenna has a 32% bandwidth for both the reflection coefficient below ™17.8dB and the sidelobes of the radiation pattern in vertical plane below ETSI Class 3 envelope, based on the simulated results.
