Design of Novel Filtenna for Wireless Applications

Al-Furat Journal of Innovations in Electronics and Computer Engineering
In this paper, a novel design based on a dual-mode ring resonator, the filtering balun, feeding the printed dipole antenna, the filter balun antenna (FBA), is presented. One port on the structure allows the signals to be phase-shifted 180 degrees from one unbalanced port to two balanced signals.
