|Title:||Goubau-Line Leaky-Wave Antenna for Wide-Angle Beam Scanning from Backfire to Endfire|
|Citation:||IEEE Antennas and Wireless Propagation Letters, 2018, Vol.17, 8, pp.1571-1574|
|Abstract:||A Goubau-line leaky-wave antenna (LWA) with a large scanning angle is presented in this letter. In contrast to the conventional Goubau-line leaky wave with a small scanning angle range, this letter employed a periodically bending Goubau line, which not only brings in a periodic perturbation for leaky-wave radiation, but also enhances the scanning range due to the increased delay for each line element. The simulation and experimental results show that the proposed LWA provides 90 radiation efficiency and 7-10 dBi radiation gain from backfire to endfire through broadside as frequency changes. The proposed antenna features good radiation performance and has a compact and low-profile configuration. 2011 IEEE.|
