✦ Synopsis

Figure 7 Measured S-parameters of the microstrip passive dualbeam scanning leaky-wave antenna two-feed topology for the active leaky-wave antenna in order to create a dual-beam radiation pattern, and vary the frequency of the HEMT VCO to control a two-directional scanning beam. The total measured scanning angle of this active antenna can be steered over a range of angle 44Њ. The measured S-parameters, the return loss S and the transmis-11 sion coefficient S , show that this dual-beam scanning 21 leaky-wave antenna has the properties of wide bandwidth and high efficiency. This antenna design can be very useful in an automotive radar system, mobile communication, and a per-Ž . sonal communication system PCS ; meanwhile, it can also be easily implemented into a monolithic leaky-wave array module.
