Abstract: A compact printed ultra-wideband (UWB) antenna with two notched stop
bands is analyzed and presented. By introducing a unit complementary split ring
resonator (CSRR) in the beveled edges of radiating patch, two sharp notches are
achieved at frequencies of 3.5 and 5.8 GHz. The proposed antenna has been
fabricated and experimentally tested. A good agreement between simulated and
measured results has been observed. Measured impedance bandwidth of the tested
antenna is 3.12–12 GHz, which covers bandwidth requirement of UWB
frequency band, for VSWR < 2 and also has two notched stop bands of
3.39–3.90 and 5.52–6.44 GHz, for VSWR > 2, for rejecting WiMAX
and WLAN band signals, respectively. In addition, the effect of the dimensions
of the CSRR on the two stop bands is also analyzed. The radiation pattern and
gain characteristics of the proposed configuration are studied and the results
are exhibited accordingly.
