A modified semicircular ground plane with a slotted circular UWB monopole antenna designed for notched applications. The proposed antenna comprises the semicircular partially ground plane and three rectangular slots with a circular patch. Certain narrow-band wireless communication systems, such as those operating at 3.6–4.9 GHz, 5.6–6.4 GHz and 8.4–9.6 GHz for satellite communication, coexist throughout the whole UWB operational bandwidth. The suggested antenna's obtained impedance bandwidth is 7.6 GHz (3-10.6 GHz). This antenna's other benefits include its small size (18 × 24 × 1.6 mm3), realized gain, directivity and uniform radiation properties across the entire passbands.
