Wideband matching circuit design for differantial output systems by using real frequency technique

Abstract

In this study, an ultra wideband power transfer network is designed by using Real Frequency Technique to use single microstrip antenna with the TI CC1110. CC1110 is a Texas Instruments' transceiver device which supports 3 different frequency (315, 433 and 868 MHz) for communication. Device output is balanced and has different output impedances at different frequencies. At first a microstrip antenna is designed and power transfer network was designed between antenna and CC1110 to transfer output power efficiently to antenna at different frequencies for using same circuit.
