A broadband compact smooth horn with flat-top radiation pattern is presented in this Letter. Using a large flare angle, the whole length of the horn is reduced to 1.875λcc is the wavelength of 95 GHz) and the TE21 mode and higher order electromagnetic modes can be excited to exhibit flat-top radiation performance. The measured radiation pattern of the presented horn can achieve <1 dB amplitude ripple in a beam width range of ±10° at 85–105 GHz (21%) where the reflection coefficient is below −22 dB. It indicates that the broadband compact smooth horn with flat-top radiation pattern can be applied in wireless communication and reflector systems in the millimetre-wave band.
