Investigation on planar UWB antenna with triple band-notched characteristics

摘要

A novel ultrawideband (UWB) printed planar antenna with triple band-notched characteristics is proposed and discussed in this paper. The realization of the proposed antenna's triple band-notched characteristics is owed to slots on the ground plane and the radiating patch. By employing a curve-shaped defected ground structure (DGS) on the ground plane, a notched band of (SATCOM) 8.0–8.4 GHz is achieved. By embedding two arc-shaped slots on the radiating patch, another two notched bands of (WIMAX) 3.3–3.6 GHz and (WLAN) 5.1–5.8 GHz are achieved. The proposed antenna has been successfully simulated, fabricated, and measured. Moreover, the designed antenna is compact size and lower cost, which is benefit for UWB communication system.
