[0011] However, in order to integrate these resonant antennas in their fundamental mode of 2.45 GHz or 5.25 GHz, it must be taken into account that, for the dielectric constant of the ceramics used, a quarter wavelength already represents more than 3 cm or more than 1.4 cm, Therefore, the size of the integrated RF front-end module is much larger than

Embodiment Construction

[0040] The main idea of ​​the invention is to divide the support of the antenna function into 3 radiating parts: the first P1, whose position corresponds to the substrate S1 on which the integrated RF front-end module is located, and not to the substrate S2; the second radiating a portion P2 whose position corresponds to that of the substrate S2 supporting the integrated RF front-end module; and a third radiating portion P3 whose position corresponds to the position of the junction between the first and second radiating portions. Therefore, the antenna can be provided directly without additional feeder lines by connecting directly to the RF integrated front-end module.

[0041] Figure 2a and 2b An example of the principle of an embodiment is described for a "patch" antenna, where the size of the patch antenna is larger than the size of the RF front-end module, enabling the patch antenna to operate at its primary resonance.

Abstract

The invention relates to a frontal block for RF reception comprising a first substrate S1 and an RF integrated frontal module integrated onto a second substrate S2 supporting a radiating part P2 of the antenna. The antenna is formed moreover by - a first radiating part P1 supported by the substrate S1 - and by a junction consisting of a third radiating part P3 linking the first radiating part P1 and the part P2 supported by the substrate S2.

Description

technical field [0001] The present invention relates to integrated front-end blocks, and more particularly, to the integration of antennas into RF integrated front-end modules. Background technique [0002] One of the purposes of this invention within the scope of the Gigabit wireless technology project is to propose a solution for RF integrated front-end modules and associated antennas for applications implementing WLAN standards, especially 802.11bg and 802.11a. [0003] The use of "system-in-package" (SIP) technology makes it possible to reduce the manufacturing costs of such modules. Thus, within the module, baluns, filters, power amplifiers, low noise amplifiers and switch-type functions will be integrated, as well as adaptation networks associated with some of these functions. Materials with increased dielectric constants may be used, for example ceramics used with a specific manufacturing method known as LTCC (Low Temperature Co-fired Ceramics). These materials thus...
