A novel ultrawideband planar slot antenna is presented. In this design, one semicircular structure is etched from the ground plane and the end of microstrip-fed structure also adopts the same structure with another dimension. The simulated and measured results demonstrate that this antenna can provide at least 11:1 impedance bandwidth (VSWR≤2) and good radiation characteristics. Compared with other...
In this letter, we present a novel printed monopole antenna for ultrawideband (UWB) applications. The proposed antenna consists of a square radiating patch with two rectangular slots and a ground plane with inverted T-shaped notch, which provides a wide usable fractional bandwidth of more than 120% (3.1212.73 GHz). The proposed antenna is simple and small in size. Simulated and experimental results...
Microstrip Antennas (MSAs) consist of a metallic radiating patch on one side of thin dielectric substrate and other side is ground plane. Most important advantages of MSAs are low profile, light weight and compatibility with integrated circuit technology. MSAs are used in mobile communication, satellite communication, radar, direct broadcasting, global positioning systems and remote sensing. The major...
