RADIOFREQUENCY MODULE

摘要

A radio frequency module comprises an antenna assembly on a semiconductor integrated circuit that can transmit an electromagnetic signal in a frequency band of interest, or receive an electromagnetic signal in a frequency band of interest, or both. In the radio frequency module, a conductive layer that forms a signal ground plane. At least one semiconductor layer of the semiconductor integrated circuit forms part of this dielectric spacing. The dielectric spacing is arranged so that an electromagnetic signal in the frequency band of interest that traverses through the dielectric spacing from the antenna assembly to the conductive layer that forms the signal ground plane experiences a phase shift comprised in the range between 60 and 120 degrees.

1. A radiofrequency module comprising:
an antenna assembly (4) on a semiconductor integrated circuit (3) arranged to carry out at least one of the following functions: transmitting an electromagnetic signal in a frequency band of interest, and receiving an electromagnetic signal in the frequency band of interest; a conductive layer (8) that forms a signal ground plane; and a dielectric spacing (d1, d2) between the antenna assembly and the conductive layer that forms the signal ground plane, whereby at least one semiconductor layer (d1) of the semiconductor integrated circuit forms part of the dielectric spacing, the dielectric spacing being arranged so that an electromagnetic signal in the frequency band of interest that traverses through the dielectric spacing from the antenna assembly to the conductive layer that forms the signal ground plane experiences a phase shift comprised in a range between 60 and 120 degrees.
