Abstract
An integrated RF front-end module for use in a communications device, such as a mobile phone. The RF front-end module is made from a laminated structure consisting of a plurality of layers. At least one of the layers is used to embed RF electronics. Microvias are disposed in various layers of the laminated structure so as to provide electrical connections to the embedded RF electronics. Two electrically conductive layers are provided on both sides of the laminated structure for shielding the RF components against electromagnetic interference. An antenna has one or two radiating elements disposed on one or both sides of the laminated structures for conveying RF signals to and from the RF electronics. The antenna can be fine-tuned and the operational frequency range of the antenna can also be changed.
