WHITTOW, W.G., 2012. Manipulating microsized coupling gaps for reconfigurable antenna applications. Microwave and Optical Technology Letters, 54 (10), pp. 2444 - 2445
Synthetically arranged microlines (width ≤ 1mm) have been considered for antennas and radiating structures at microwave frequencies. Finite-difference time-domain simulations show how the electrical size of the structure and multiple resonances can be controlled by carefully introducing microsized gaps.
