Abstract :
This letter presents a theoretically rigorous investigation and experimental verification for an asymmetrical, unequal power divider working at dual frequency bands. Through the even- and odd-mode analysis that can be applied to dual-band, unequal power divider by assuming virtual open and short points, analytically exact solutions have been derived for the design parameters values. For verification of this analysis, commercially available software including ADS and CST MWS based on circuit theory and full-EM theory, respectively, and already-established equations have been adopted.
