Abstract
A slot fed microstrip patch antenna () includes an electrically conducting ground plane (), the ground plane () having at least one coupling slot () and at least a first patch radiator (). An antenna dielectric substrate material () is disposed between the ground plane () and the first patch radiator (), wherein at least a portion of the antenna dielectric () includes magnetic particles (). A feed dielectric substrate () is disposed between a feed line () and the ground plane (). Magnetic particles can also be used in the feed line () dielectric. Patch antennas according to the invention can be of a reduced size through use of high relative permittivity dielectric substrate portions, yet still be efficient through use of dielectrics including magnetic particles which permit impedance matching of dielectric medium interfaces, such as the feed line () into the slot ().
