    Abstract: The present invention relates a circular polarization antenna (1) configured to pick up an electromagnetic wave with a frequency greater than or equal to 2.4 GHz and less than or equal to 2.5 GHz, and resonate at the frequency of said electromagnetic wave. The antenna (1) comprises a substrate (2) comprising a first face (21) and a second face (22), opposite to said first face (21), and a first layer (3) of metallic material arranged on said first face (21). In particular, said substrate (2) is made of a ceramic material having an isotropic dielectric constant greater than or equal to 11 and less than or equal to 14, and has a cavity (20) arranged centrally with respect to said second face (22). The present invention relates also to a system for storing electrical energy comprising said antenna.

    Abstract: The screw (10) has a longitudinal axis (12) and comprises a threaded shank (13) and a head (14) wherein a socket (16) is formed to be engaged by a wrench and having a pluri-lobed outer profile comprising a series of lobes (18) circumferentially offset and separated by a series of circumferentially offset protrusions (20) of the head (14). Each protrusion is delimited by two flanks (22) and a front length (24) joining the radially inner ends of the flanks (22) and is convex and symmetrical with respect to a center axis (26) radially oriented with respect to the longitudinal axis (12). The front length (24) is formed by a center face (28) and two inclined side faces (30) each of which joins the radially inner end of the respective flank (22) with a respective end of the center face (28), which is oriented orthogonally with respect to the center axis (26) of the protrusion (20).
