Abstract :
This paper presents an analysis of slot antennas with or without a dielectric overlay fed by a dielectric image line. The power (reaction) at the aperture is determined using the Green´s function in the spectral domain. This reaction and the change in modal voltage of the dielectric image line at the aperture are used to determine the impedance of the slot antenna. This analysis can be extended to slot antenna arrays fed by dielectric image lines that are useful at millimeter-wave frequencies.
