摘要：

The paper describes the design of microstrip leaky-wave antennas for single and dual-beam applications. Dispersion curves for the first higher order mode are given by analytical expressions with the help of a simple cavity model. From knowledge of the propagation characteristics, the radiation patterns of the leaky-wave antennas are easily computed. The antennas are excited by open-ended CPW lines which both present a good coupling efficiency and high potentiality for the insertion of active circuits. Several C-band applications on various substrates are presented, showing the usefulness and the easy design of microstrip leaky-wave antennas for the realisation of steerable dual-beam patterns.
