AbstractIn this letter, a novel broadband microstrip-fed slot antenna with double rejection zeros is proposed and developed by constructing simultaneously a wide-slot radiator and a quarter-wavelength microstrip line resonator. A comprehensive explanation on its operating principle is at first given by using an equivalent two-pole filtering network, in which the radiation resistance is perceived as the output impedance. Extensive numerical results are then obtained using commercial electromagnetic simulator to demonstrate its attractive broadband feature. Finally, a few antenna samples are designed, fabricated, and measured to verify the predicted performance. Experimental results exhibit that the bandwidth of this proposed antenna configuration is significantly increased up to 32.0% as compared to 9.0% of its traditional counterpart.
