Compact Bow-Tie Quasi-Self-Complementary Antenna for UWB Applications

In this letter, a bow-tie quasi-self-complementary antenna (QSCA) for ultrawideband (UWB) applications is presented and discussed. By a coplanar waveguide (CPW)-like matching technique, the proposed antenna provides a broad VSWR <; 2:1 impedance bandwidth from 3.04 to 11.47 GHz. This feature is in favor of covering the required bandwidth from 3.1 to 10.6-GHz UWB operations. Additionally, the compact size (10 × 35 mm2) of the antenna is favorable for integration with wireless communication devices on restricted radio-frequency elements space.
