just wondering if anyone could share their experiences or suggest any texts discussing how antenna design affects the playability of a theremin.
i'm particularly interested in how the antenna design affects the distance over which the circuit will be sensitive to hand movements. for example, are thin antennas better at detecting movement at a greater distance than thicker ones? what about material density, type of metal, cross-sectional shape, or whether it is hollow or solid?
my current project is a digital theremin that outputs 16bit data rather than sound. i'm using a QProx QT300 capacitance-to-digital sensor. so far, i'm only getting readings when my hand is about 10cm away from my metal plate "antenna" or closer.
the project's in very early stages at the moment, but you can see little bit about it here:
