The physical mechanisms underlying the dramatic reduction of the unit cell electrical size along with broadening fractional bandwidths provided by intertwined spiral arrays are discussed. Based upon this insight, a multi-strip transmission line (MTL) model is developed to analytically estimate the equivalent capacitance and inductance of intertwined spiral array elements in terms of their geometrical parameters. The proposed MTL model enables an accurate prediction of the fundamental resonance characteristics and provides a valuable tool for design of the arrays with the specified frequency response.
