Abstract: Broadband printed dipoles of different shapes are investigated. Because of the least resistance fluctuation with frequency, trapezoidal dipole has been chosen. Two-dimensional array with printed trapezoidal dipoles operating at 4-10 GHz frequency range is designed and realized. Feeding network and radiating elements are in the same plane, so that the array is realized on the single dielectric substrate. Reflector plate is placed behind a substrate with antenna elements. Achieved antenna gain in the whole frequency range is within 20.5 and 24.8dB, VSWR is less then 2.1 and maximum loss about 3dB.
Key words: Antenna, antenna array, printed antenna, VSWR, radiating element, monopole array.
