Abstract
Presented is an electrically small multiband monopole antenna based on complementary split‐ring resonators, which are used to reduce antenna size. The antenna is fed by a three‐stage microstrip line and provides 13, 17 and 16% impedance bandwidth performance covering the 3.5 GHz WiMAX and 2.4/5.2 GHz WLAN bands. Also, the proposed antenna exhibits almost an omnidirectional radiation pattern in the H‐plane and a dipole‐like radiation pattern in the E‐plane. The return loss and radiation pattern measurements of the fabricated antenna are in very good agreement with simulation results.Keywords
