  • SURFACE ACOUSTIC WAVE DEVICE AND APPARATUS INCLUDING THE SAME
    Publication number: 20160134255
    Abstract: A surface acoustic wave device includes: a piezoelectric substrate; an interdigital transducer disposed on the piezoelectric substrate, the interdigital transducer being configured to transduce a driving signal into a surface acoustic wave, and transduce a reflected surface acoustic wave into a response signal; a reflector arranged on the piezoelectric substrate and configured to reflect the surface acoustic wave input from the interdigital transducer; a first antenna disposed on the piezoelectric substrate, the first antenna extending radially from the interdigital transducer, and the first antenna being configured to receive the driving signal and transmit the response signal; and a second antenna disposed on the piezoelectric substrate, the second antenna extending radially from the interdigital transducer to be asymmetrical with respect to the first antenna, and the second antenna being configured to receive the driving signal and transmit the response signal.
