Meta-antenna: Mechanically Frequency Reconfigurable Metamaterial Antennas
summary
A design and fabrication pipeline creates mechanically reconfigurable metamaterial antennas that shift resonance across 500 MHz to 6.3 GHz (≥10 dB) by compression, bending, or rotation, simulated in an Ansys editor and measured with a LiteVNA. Fabrication uses laser‑cut rubber, spray‑painted silver‑copper conductors and SMA probing; measured simulation error averages 0.873 GHz, acrylic coating shifts ≤33 MHz (<1%), and structures remain functional after 10,000 compression cycles. A headphone demo toggles modes with a 0.12 GHz headphone toggle.
