Active Integrated Dielectric Resonator Antenna-in-Package Design

This letter proposes a packaged active integrated dielectric resonator antenna-in-package (AIDRAiP), which consists of a hollow rectangular dielectric resonator antenna (RDRA), and internally packaged power amplifier and bandpass filter chips. First, a modified annular slot feeding structure is proposed to design an RDRA with a wide -10 dB bandwidth of 20.6%. Then, by integrating an amplifier and a filter chip into a hollow RDRA, a well-packaged AIDRAiP is developed with the circuits and antenna on the same side of a substrate. The size of the AIDRAiP is the same as that of the hollow RDRA. A -10 dB band of 2.38-2.52 GHz (determined by the bandpass filter) and a gain of about 15.0 dBi are achieved for the AIDRAiP prototype, with a reasonable agreement obtained between the measured and cosimulated results.
