Claim 0:
1. A patch antenna, comprising:
a multilayer printed circuit board, wherein a calibration network for the patch antenna, an array of patch radiators and a feed network for the array of patch radiators are integrated on the multilayer printed circuit board,
wherein the multilayer printed circuit board includes, from top to bottom, a first dielectric substrate, a second dielectric substrate, a third dielectric substrate and a fourth dielectric substrate, each of the first through fourth dielectric substrates having an upper major surface and a lower major surface opposite the upper major surface,
wherein the feed network for the array of patch radiators comprises a first feed network and a second feed network for the array of patch radiators, wherein the array of patch radiators is disposed on the upper major surface of the first dielectric substrate, wherein a first ground metal layer is provided between the first dielectric substrate and the second dielectric substrate, wherein a first metal pattern is provided between the second dielectric substrate and the third dielectric substrate, wherein the first metal pattern comprises the first feed network for the array of patch radiators, and a second metal pattern is provided between the third dielectric substrate and the fourth dielectric substrate, wherein the second metal pattern comprises the calibration network and the second feed network for the array of patch radiators.
