Zusammenfassung:Wireless surface acoustic wave sensors are an attractive solution to harsh environment sensing. In this paper we explore several different compact antenna designs for use with langasite SAW devices. We find that folded dipole and meander dipole antennas represent a good compromise between physical size and efficiency of coupling between the antenna and the SAW device. Wireless operation has been achieved up to 650°C with a meander dipole that is about one quarter wavelength in the largest dimension.
