In work the way of construction of the multiband antenna array formed inlayed unbalanced tem-horn antennas is offered, allowing to create compact antenna systems, elements which it is easy feed in a ultrarwideband of frequencies by means of coaxial or strip lines. Perspectivity of use of investigated antenna elements in mobile and onboard systems of the radio control is shown.
Variants of designs of the antenna array which elements are characterised by average entrance resistance 100 Ohm and 50 Ohm are considered. It is shown that presence of internal antenna elements insignificantly changes entrance characteristics and the directed properties of an external radiator in a ultrarwideband of working frequencies.
By the qualitative theoretical analysis and numerical electrodynamic modelling it is shown that use quasi-fractal a principle of construction of the multiband antenna systems functioning in each of ranges in a ultrarwideband of frequencies, is perspective for reduction of their overall dimensions.
