Abstract :
A miniaturized Gysel power divider (PD) is developed by using composite right-/left-handed (CRLH) transmission lines (TLs) consisting of microstrip lines and lumped elements. The theoretical closed-form design equations are presented to calculate the element values of the CRLH TLs. For verification purpose, a miniaturized Gysel PD based on CRLH TLs for GSM frequency of 900 MHz is designed, simulated, fabricated, and measured. The proposed Gysel CRLH TL PD is extremely compact, occupying only 18.2% of the conventional microstrip line-based Gysel PD. Less than 1 dB insertion loss has been achieved at the center frequency. Also, the simulated results agree well with the measured results.
