In this paper the problem of obtaining efficient broadside radiation in one-dimensional (1-D) periodic printed leaky-wave antennas (LWAs) is addressed. In particular, a technique for the elimination of the open stopband (OSB) is presented, which is based on a p network that matches the Bloch-wave impedance of the structure to a desired (non-zero) value at broadside. Three different matching conditions are investigated. Their advantages and drawbacks are briefly discussed and the effectiveness of the technique is demonstrated on a real structure.

Abstract
In this paper the problem of obtaining efficient broadside radiation in one-dimensional (1-D) periodic printed leaky-wave antennas (LWAs) is addressed. In particular, a technique for the elimination of the open stopband (OSB) is presented, which is based on a p network that matches the Bloch-wave impedance of the structure to a desired (non-zero) value at broadside. Three different matching conditions are investigated. Their advantages and drawbacks are briefly discussed and the effectiveness of the technique is demonstrated on a real structure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
