The shape of the proposed radiator is based on a multi-resonant structure. Developed planar tree has symmetrical branches with different length and is fed by a coplanar waveguide (CPW) with modified edge of the ground plane. The antenna of size 29 mm x25 mm has been designed on Taconic - RF-35 substrate (r = 3.5, tg= 0.0018, h = 0.762 mm). The paper shows simulated and measured characteristics of return loss, as well as measured radiation patterns. The proposed antenna could be a good candidate for broadband applications (for instance: wideband imaging for medical application and weather monitoring radars in satellite communication etc.)}, type={Artykuły / Articles}, title={Compact Coplanar-fed Tree-shaped Antenna}, URL={http://journals.pan.pl/Content/110211/PDF/24.pdf}, doi={10.24425/ijet.2019.126298}, keywords={broadband antenna, fractal antenna, reflection coefficient, defected ground structure, coplanar waveguide}, }
