Abstract :
Single-arm wire spirals printed on grounded dielectric substrates are analysed using a moment method algorithm which uses piecewise sinusoidal subdomain basis and test functions on curved segments, which follow exactly the spiral curvature. Results are compared with those obtained from measurements and with published results using linear segmentation, and it is shown that the curved segment model is accurate and significantly more computationally efficient
