Symmetric pi-matching networks are presented for suppressing the open stopband (OSB) and obtaining efficient broadside radiation in one-dimensional (1-D) periodic printed leaky-wave antennas (LWAs). The elimination of the OSB is achieved by matching the Bloch-wave impedance of the structure to a desired (non-zero) value at broadside frequency. Three different matching conditions can be applied. The effectiveness of the proposed techniques are demonstrated with numerical simulation on real structures.

Abstract
Symmetric pi-matching networks are presented for suppressing the open stopband (OSB) and obtaining efficient broadside radiation in one-dimensional (1-D) periodic printed leaky-wave antennas (LWAs). The elimination of the OSB is achieved by matching the Bloch-wave impedance of the structure to a desired (non-zero) value at broadside frequency. Three different matching conditions can be applied. The effectiveness of the proposed techniques are demonstrated with numerical simulation on real structures.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
