摘要： A field-confined wideband antenna assembly is disclosed. The antenna assembly includes a radiating element with a planar body that defines a first confining slot. The dimensions of the first confining slot correspond to a first set of resonance frequencies of the radiating element. A feeding line extends from the radiating element in an angularly offset relationship to the planar body. A first grounding line extends from the radiating element in an angularly offset relationship to the first body. A dielectric assembly supports the planar body of the radiating element. There is a first high frequency current loop that is formed from the feeding line to the radiating element about the first confining slot and to the first grounding line. With this, the first high frequency current loop confines current and electric fields on the radiating element.

摘要： Pins on an RFIC package carry RF signals between the package and a PCB. A first capacitor is coupled between a selected pin of the RFIC package near the pins carrying the RF signals and a radio-frequency ground on the PCB. A coupling between the RFIC package and the PCB is modeled, and includes modeling of the pins of interest and at least one parasitic element of the coupling. A capacitance of the first capacitor is selected based on the modeling to obtain desired performance at selected operational frequencies. A second capacitor may be coupled between the selected pin a radio frequency ground of the RFIC package. An inductor may be coupled in parallel across the first capacitor.
