摘要：

A compact dual band three way power divider based on the Bagley Polygon has been implemented using composite right/left handed (CRLH) transmission lines consisting of microstrip lines and lumped elements for the GSM frequencies of 860MHz and 1.92GHz. Also, a dual band power divider consisting of conventional quarter wavelength (lambda/4) transmission lines with shunt connections of open and short stubs has been implemented for comparison. An advantage of using the Bagley Polygon for three way power divider is that it allows an arbitrary phase selection at the third port by using single or dual band, CRLH or conventional transmission lines. The CRLH based power divider shows an area of 7.95 cm(2) and a bandwidth of approximately 8% at both bands while the comparison structure shows an area of 51.98 cm(2), a bandwidth of 5.8% at 860MHz, and 2.6% at 1.92GHz. Less than 5.5dB insertion loss has been achieved in both cases. Also, full wave structure simulation has been performed and the simulation results agree well with the measurement results.
