【 摘 要 】

A highly shielded and easy-integration antenna-in-package (AiP) configuration based on the rectangular hollow dielectric resonator antenna (DRA) is presented. The surfaces of the hollow are made conductive to form a metal cavity, isolating the DRA from the RF circuits. Both passive and active antennas for 2.4-GHz WLAN applications are designed, measured, and compared. The two antennas are excited in the TE_δ11^x mode and perform similarly. To know the effect of the perfect-electric-conductor (PEC) boundary, the DRA without any metal cavities is also studied for comparison. Two sets of experiments are designed to investigate the electromagnetic interference between the AiP and a low-noise amplifier (LNA) inside the hollow. The influences of the DRA on the packaged LNA are measured and analyzed for both the no-PEC-boundary and PEC-boundary cases. It is found that the output of the LNA will be significantly affected by the DRA input power when the latter is sufficiently high.
