Abstract :
A dual, metamaterials, substrate integrated, leaky-wave structures for antenna applications is proposed to improve the antenna gain. The proposed antenna consists of two composite right/left-handed substrate integrated waveguide leaky-wave structures. A common vias wall is used to combine the leaky-wave structures. The dual leaky-wave structures based antenna is designed, fabricated, and measured. The measured gain more than of 12.0 dBi with variation of 3.0 dB is achieved over the frequency range from 8.25 to 12.0 GHz. The measured beam scanning range is from -52° to 68° over a frequency band of 8.0-13.0 GHz.
