Rectangular stepped patch antenna at GSM 900 for energy scavenging
This paper presents a novel 377 Ω rectangular stepped patch antenna with partial ground plane at downlink radio frequency range of GSM-900 band. Two steps are incorporated into the patch antenna, and bandwidth expansion was investigated by the currents flowing through the patch antenna. The ante...

| Summary: | This paper presents a novel 377 Ω rectangular stepped
patch antenna with partial ground plane at downlink radio frequency
range of GSM-900 band. Two steps are incorporated into the patch
antenna, and bandwidth expansion was investigated by the currents
flowing through the patch antenna. The antenna simulation was
carried out in the ADS 2009 environment. The fabricated antenna on
FR4 substrate indicates an impedance bandwidth of 32.7% (310 MHz)
at 947 MHz centre frequency with return loss of −28.12 dB. The
simulated, test and field results of the antenna design are discussed. |
