“…However, wave propagation along a 1D closely spaced array with electrically small element is not well understood and still needs to be investigated. Previously we have simulated surface wave propagation along a 1D FCH array and compared the results with that of a 1D metal cut wire array [9]. In this paper, we extend our study to simulate and measure surface wave propagation and radiation along a 1D closely spaced FCH array.…”

Wave propagation along a closely spaced folded cylindrical helix (FCH) array is investigated for the purpose of designing compact array for energy transport and antenna radiation. It is found that the height of this surface wave guiding structure can be decreased from 0.24λ0to 0.06λ0by replacing the monopole element with the FCH. Both the propagation constant and the mode distribution of the dominant wave mechanism are extracted by ESPRIT algorithm, which indicates that a backward propagating surface wave is supported by the array structure. A compact backfire FCH antenna array is designed and measured based on the identified dominant wave mechanism.
