A strategy for enhancing the common-mode (CM) suppression of a band-notched UWB closed-aperture antenna is proposed. The antenna circuit consists of a differentially coplanar-waveguide-fed hexagonal-aperture antenna and a pair of wave-trapping slotline resonators for producing a 5.5 GHz notch band. The enhancement of the CM suppression was achieved by setting the dimension of the aperture along the longitudinal direction (i.e. the direction parallel to the feedlines) small enough, so that the first resonant mode of the CM half-circuit of the aperture antenna can be pushed beyond the differential-mode (DM) UWB passband. A fabricated balanced band-notched UWB antenna was measured to have a 10 dB DM passband of 3–11.2 GHz with a notch band of 5.1–6.1 GHz. Good measured CM suppression was observed with a maximum return loss of 2.9 dB in the DM UWB passband.
