Reconfigurable Wilkinson power divider with unity to 8dB output power differences using one varactor diode
IET Conference Publications 2018:CP746 (2018)
Abstract:
A novel reconfigurable equal to unequal Wilkinson power divider is presented. The proposed power divider adopts coupled microstrip line technique to implement a high impedance section to have unequal output power ratio. A varactor diode is placed between the coupled lines to achieve reconfigurability by changing the reverse biasing voltage on the varactor diode. This enables equal to 8 dB power division ratios between the output ports. A wide range of biasing voltage is used to achieve the smooth power division ratio. A prototype hardware is designed, fabricated and measured to validate the proposed approach. In the equal power division ratio scenario, the measured performance shows a bandwidth of 600 MHz at 5.4 GHz centre frequency. A higher bandwidth of 750 MHz is obtained in the case of unequal power division ratios.UWB-based Single-anchor Low-cost Indoor Localization System
