Abstract
An antenna module includes a multilayer board, a radio frequency (RF) chip, and a active device array. The multilayer board includes an antenna that transmits and receives electromagnetic waves through a top surface of the multilayer board. The RF chip, on a bottom surface of the multilayer board, is connected to the antenna and processes an RF signal. The active device array, on the bottom surface of the multilayer board, includes active devices, a first input pin and a first output pin. The first input pin and the first output pin are respectively connected to electrodes of an active device of the active devices. The multilayer board includes a first pattern for a first signal to be provided from the RF chip to the first input pin, and a second pattern for a second signal to be provided from the first output pin to the RF chip.
