Patent ID: 8477070

Claim:
An integrated antenna and chip package comprising: a first substrate having a first surface and a second surface, the second surface configured to interface the chip package to a circuit board being made of a first dielectric material; a second substrate disposed on the first surface of the first substrate, the second substrate being made of a second dielectric material; a communication device disposed on the second substrate; an antenna disposed on the second substrate and coupled to the communication device, the antenna further comprising: a common differential feed point having a positive terminal and a negative terminal coupled to corresponding terminals of the communication device; a differential feed line pair comprising a first feed line having a distal end coupled to the positive terminal and a second feed line having a distal end coupled to the negative terminal, wherein the first and second feed lines are adjacent to one another at the distal end; a first patch antenna connected to a proximal end of the first feed line; and a second patch antenna connected to a proximal end of the second feed line, the first patch antenna and the second patch antenna are spaced a full guide wavelength apart, wherein the first and second patch antennas are configured to maximize energy transfer efficiency therebetween to operate as a single full-wave structure at millimeter wave frequencies; and a lid coupled to the first substrate and configured to encapsulate the antenna and the communication device, the lid having a lens configured to allow radiation from the antenna to be emitted therethrough.
