A method of frequency invariant near-field broadband beamforming is proposed in this paper. The output signals of a uniform concentric circular array (UCCA) are converted into phase mode signals by using inverse discrete Fourier transform (IDFT), and a far-field array with frequency invariant response is then approximately achieved by using the near-field correction and frequency compensation network. Therefore, the traditional far-field narrow-band beamforming methods can be extended to the proposed near-field broadband array. The simulation results show that the array response of the near-field broadband array is approximately frequency invariant, and its beam pattern is also similar to that of the far-field narrow-band array. In addition, compared with other beamforming methods, the performance of the proposed frequency invariant near-field broadband array is significantly improved with even lower computational complexity.
