Gg. Gentili et al., GREENS-FUNCTION ANALYSIS OF SINGLE AND STACKED RECTANGULAR MICROSTRIPPATCH ANTENNAS ENCLOSED IN A CAVITY, IEEE transactions on antennas and propagation, 45(4), 1997, pp. 573-579
A rigorous Green's function analysis of rectangular microstrip patch a
ntennas enclosed in a rectangular cavity is described, The formulation
makes use of a frequency-independent preprocessing (image extraction)
on the spectral domain representation of Green's function, Measured a
nd simulated results are shown for both single and stacked-patch anten
nas enclosed in a cavity.
