WebA uniplanar millimeter-wave broadband printed log-periodic dipole array (PLPDA) antenna fed by coplanar waveguide (CPW) is introduced. This proposed structure consists of several active dipole elements, feeding lines, parallel coupled line, and the CPW, which are etched on a single metallic layer of the substrate. The parallel coupled line can be … WebCoplanar Waveguide Feed System Performance and Antenna Integration The measured return loss (S 11 ) and insertion loss (S21) of the CPW/Microstrip line post coupler is shown in Fig. 7. The return loss and insertion loss are better than 10 and 1 dB, respectively, over a wide band of frequencies extend- WebCOPLANAR WAVEGUIDE-FED PLANAR SPIRAL ANTENNA WITH INTEGRATED IMPEDANCE TRANSFORMER Zeynab Vahidpoor A new planar spiral antenna with integrated impedance transformer is presented which needs no external balun and can be fed by a coplanar waveguide. free online roulette play
