Abstract. UWB omnidirectional in magnetic plane printed linear antenna array is proposed and investigated. The array has even number of printed dipoles that are fed via an in phased power divider on the base symmetric two-strip line in a meander form. The two-element and four-element antenna arrays are simulated and optimized using the finite element method. The study of the matching and radiation characteristics of optimized arrays shows that the two-element array has the matching bandwidth 70% and 2.3 – 5 dB gain with variation less than 1.5 dB in H-plane, and the four-element antenna array has the matching bandwidth more than 60% and 5 – 8 dB gain with variation less than 1 dB in H-plane. The two-element array sample is fabricated and measured. There is a good agreement between simulated and measured results.

Key words: UWB antenna, omnidirectional in magnetic plane antenna, printed dipole, linear antenna array.
