Abstract. Using the finite element method (FEM) and the finite-difference time-domain method (FDTD), a numerical study of the matching and radiation characteristics of E – plane TEM horn linear arrays of three types: classic (regular) TEM horns, exponentially - expanding TEM horns and square - irregular TEM horns, the angles in E and H plane of which are monotonically decreased towards the aperture are conducted. The first goal of this work is to investigate the possibility of using the horns mutual coupling effect to reduce the lower matching frequency of small-number-element E –plane TEM horn linear array of different types. The characteristics of these linear arrays are compared with the ones of 90-degree biconical elements. For in-phase linear arrays the realization possibility of over region band of frequencies (frequency band more than 1:10) is shown. The second purpose of this work is to research the radiation characteristics, including the front-to-back ratio of radiation of small-number-element E-plane TEM horn linear arrays of different types.
