| Summary: | A novel 377 Ω patch antenna operating
at GSM 900 downlink band for RF energy
harvesting is proposed and analyzed in this paper.
The designed antenna consists of a normal patch
with two steps incorporated at the appropriate
position to enhance its bandwidth. The antenna is
designed and tested in Agilent advance design
systems ADS environment and constructed on a
FR4 substrate. The antenna yields an impedance
bandwidth of 34.35% (325 MHz) at 946 MHz
centre frequency with a return loss S11 of -29.22dB
and gain of 5.2 dBi. The proposed patch antenna
is suitable for ambient RF energy harvesting at
downlink frequency band of GSM 900 as
demonstrated by simulation and experimental
results. The measured results closely agree with
the simulated results. |
