Abstract
The periodic leaky wave antenna (PLWA) by orthogonally bending microstrip transmission line is presented in this paper. The proposed antenna consists of periodically orthogonally bending microstrip transmission line. The calculation formula of the propagation wavenumber of this antenna is given, and the calculated results and measured results are matched. A simple technique to eliminate the open stopband (OSB) is presented. The prototype antenna was simulated, fabricated and measured, The measurement results show that the main beam scans continuously and from −55° to 63° in y-z plane when the operating frequency increasing from 3.7 GHz to 6.8 GHz. The structure of this PLWA is simple and easy to fabricate.
