Apparatus and methods for packaging dielectric resonator antennas with integrated circuit chips
View Patent ↗Apparatus and methods are provided for integrally packaging antenna devices with semiconductor IC (integrated circuit) chips, wherein IC chips are packaged with dielectric resonators antennas that are integrally constructed as part of a package molding (encapsulation) process, for example, to form compact integrated radio/wireless communications systems for millimeter wave applications.
1. An electronic package apparatus, comprising:
a package frame;
an IC (integrated circuit) chip mounted to a die paddle of the package frame, the IC chip having an antenna feed network formed on an active surface thereof electrically connecting the IC chip to package leads of the package frame;
a dielectric resonator antenna stacked on the active surface of the IC chip and aligned to a portion of the feed network; and
a package cover formed over the IC chip and the dielectric resonator antenna, wherein the dielectric resonator antenna has one surface that is exposed through the package cover, and wherein a portion of the package cover is disposed between the die paddle and the package leads.
2. The apparatus of claim 1 , wherein the dielectric resonator antenna is formed by injection molding using a first dielectric material.
3. The apparatus of claim 2 , wherein the package cover is an encapsulation material that is formed by injection molding using a second dielectric material, wherein the second dielectric material surrounds the first dielectric material.
4. The apparatus of claim 3 , wherein the first dielectric material has a first dielectric constant and the second dielectric material has a second dielectric constant, wherein the first dielectric constant is greater than the second dielectric constant.
