摘要
A dielectric loaded microstrip patch antenna is provided for deliveringrelatively wideoperational bandwidth dual-band, with relatively good isolation andflexibility forcircular polarization, while having a compact design and lightweight to suitmobile andwireless applications. The microstrip patch antenna has a conducting groundplane and apatch radiator. The patch radiator is spaced from the ground plane by asubstantialdistance having a first dielectric material therein. A slot feed in the groundplane providesthe patch radiator with radio signal energy across the space having the firstdielectricmaterial therein. A piece of a second dielectric material is disposed adjacentthe slot feedbetween the patch radiator and the ground plane. The second dielectricmaterial has adielectric constant that is higher than the dielectric constant of the firstdielectric material.The piece of the second dielectric material acts to load the feed in order toimprovecoupling between the slot and the patch. The piece has a dimension along oneof the xand y axes smaller than a dimension of the patch along a same axis. Since thepiece issituated between the ground plane and the patch it determines operationalcharacteristicsof the microstrip patch antenna.
