Ultrawideband (UWB) technology provides high-speed data communication for short-haul wireless applications. The design of an efficient UWB antenna is a challenge, since it needs to cover a broader range, reliable gain, and good impedance matching over the operating frequency band. Several structures have been proposed in recent years for the design and development of UWB antennas. In this paper, a compact six different antenna structure is investigated and presented for UWB applications. The presented UWB antenna structures have hybrid geometry and are composed of a modified radiating element on the top of the FR-4. A modified ground plane is at the bottom of the substrate with 50 O microstrip line feed. The funnel-shape antenna exhibits the magnitude of S11 < -10 dB, among the proposed UWB antenna structures, between a 2.4 and 14.3 GHz frequency range that represents a 142 percentage of fractional bandwidth.
