Abstract :
A beam-switchable scanning leaky-wave antenna (LWA) integrated with p-I-n diode switch circuits has been developed in this paper. This LWA with a two-terminal feeding microstrip line structure is integrated with a SPDT (single port double throw) switch as a control circuit. Compared with traditional leaky-wave antennas, this configuration offers the advantage of one/dual beam scanning radiation pattern. On the dual-beam mode, the scanning angle is steered over a range of 36° to 64° for the right beam and 144° to 116° for the left beam. On the one-beam mode, the scanning angle is measured over 20° for the right beam. The measured result shows that we can change the one-beam mode or the dual-beam mode electronically by controlling the on/off status of a SPDT
