Mechanically driven SMR‐based NEMS magnetoelectric antennas

The miniaturization of antennas has been a significant challenge in the field electronics and telecommunications. In recent years, mechanically driven thin-film bulk acoustic resonator (FBAR) magnetoelectric (ME) have emerged as promising solution, demonstrating superior capabilities compared to conventional state-of-the-art compact antennas. While nanoelectromechanical systems (NEMS) FBAR ME exhibit high potential, their suspended heterostructure render them fragile low power handling capabilities. Our findings demonstrate that solid-mounted (SMR) NEMS on Bragg resonant reflector offer compelling solution. With circular resonating disk 200 μm diameter operating at 1.75 GHz, these SMR-based display antenna gain -18.8 dBi 1dB compression point (P1dB) 30.4 dBm. Compared same-size with free-standing membrane, significantly higher structural stability 23.3 dB stronger capability, addition easier fabrication processes. compatibility simple processes complementary metal-oxide-semiconductor (CMOS) technology, along dramatic miniaturization, handling, robust mechanical properties much radiation gain, make candidate for future systems.
