| 16. A phase shifter, comprising:
an input port for receiving a radio frequency (RF) signal;
a power dividing means for dividing the RF signal into a first divided signal and a second divided signal having a fixed phase
value; and
an output port for outputting the second divided signal having the fixed phase value;
wherein the first divided signal is divided into at least two signals, the at least two signals being shifted in phase based
on a path length of the at least two signals,
the power dividing means includes:
a first induction unit electrically connected to the output port;
a dielectric located on the first induction unit; and
a second induction unit located on the dielectric.
