Excitation networks for two-element ultra-wideband antennas

Ultrawideband planar antennas and antenna arrays

“…Second structure consists of two-element UWB antenna for UWB application in ETSI range 6.0-8.5 GHz with excitation balun device carried out as broadband hybrid -network with two inputs and two outputs with connected to two UWB planar radiators (Fig. 6,a) [12]. The structure and dimension (in mm) of the first designed two-element antenna is presented in Fig.…”

“…Second designed UWB antenna novel consists of hybrid based on stripline technology cover frequency range for use in UWB systems according ETSI standards 6-8.5 GHz [12]. Proposed solution can be easily implemented together with printed UWB two-element monopole radiators on the same laminates.…”

“…Whole structure of the two-element UWB antenna with optimal broad-band transmission lines and excitation network, as planar hybrid is shown in Fig. 6,a [12].…”

“…This paper presents results of design and investigation of UWB planar antennas obtained in Bialystok University of Technology, Poland (7)(8)(9)(10)(11)(12)(13).…”
