Abstract :
The radiation properties of a variety of open microstrip discontinuities have been studied. The full electromagnetic analysis performed has been shown to characterize microstrip corners, steps, and matching sections accurately. The technique used solves Pocklington´s integral equation for the unknown current distribution of the conducting sections by an application of the method of moments in the space domain. The radiated field is evaluated using a steepest descent method. The analysis accurately accounts for all substrate effects. The technique is used to characterize a single-loop meander inductor. The radiated power over a wide frequency range is shown, and the radiated power above 30 GHz is found to be quite significant.<>
