Xh. Shen et al., STUDY OF GAIN ENHANCEMENT METHOD FOR MICROSTRIP ANTENNAS USING MOMENTMETHOD, IEEE transactions on antennas and propagation, 43(3), 1995, pp. 227-231
The moment method is used to determine the radiation and impedance pro
perties of microstrip patch antennas in multilayered material configur
ations. The resonance conditions for the layer structure which allow f
or high gain are studied. The gain, the impedance, the beamwidth, and
the bandwidth are discussed.
