In designing metamaterial antennas, we’re always pushing for miniaturization. What’s the real impact on performance when we scale down the unit cell size, and where do we hit fundamental limits?
I'm an RF engineer working on compact antenna arrays. We use metamaterial structures for enhanced gain and directivity, but I'm concerned about scaling. Intuitively, smaller unit cells should allow for a more refined effective medium and a smaller antenna footprint. However, I need to understand the practical trade-offs: how does scaling affect the bandwidth, radiation efficiency, and resonance stability, especially as we approach fabrication limits at microwave or millimeter-wave frequencies?
