ABSTRACT In this work, an LNA module is moved into a corner-truncated patch antenna, which is intended for GPS reception use. A cavity is formed within the substrate of the patch to accommodate the LNA module. The built-in LNA enhances the antenna reception capability without adding external circuits. Hence, the resulting patch has the same footprint and thickness as ordinary passive patches. Simulations and measurements on prototype antenna indicate that the built-in LNA module imposes limiting influences on the antenna properties, which can be corrected by rescaling the patch, and is hence an attractive option for making small antennas with large gains
