Abstract:
Fifth generation (5G) is an advanced telecommunication standard as it is
assumed that it will provide high bandwidth, rise in data rates, the reliability of connectivity and coverage, together with the huge reduction in energy
consumption and latency. 5G’s main requirements are development of green
technology (energy harvesting) and reduction in the consumption of power
by the devices. For this purpose, the idea of Simultaneous Wireless Information and Power Transfer (SWIPT) is introduced as it enables simultaneous
transfer of energy and information wirelessly. In a SWIPT system, it is not
feasible to execute energy harvesting (EH) and information decoding (ID) on
the same received signal as the signal’s information content is destroyed when
EH performed on the RF signal. Therefore, the power splitting technique is
used in which the power divider is utilized for dividing the received signal
into two different power levels with a certain power splitting ratio.
The premier focus of this thesis is to design the tunable power divider
having good isolation which helps in splitting power with different ratios.
The compact two-way tunable power divider using varactor diode for SWIPT
systems is designed in this thesis. The proposed power divider is designed
at 2.4 GHz and the achieved power ratios vary from 13:1 to 28:1 with the
isolation better than 12 dB is achieved between the output ports of the power
divider.
