Embodiment Construction
[0043] figure 1 a to figure 1c depicts an embodiment of a planar rectilinear arrangement of vertically polarized radiation elements 1 . The radiating element 1 contains a half-wave dipole 2 consisting of two half-dipoles separated by a slot 3, each half-dipole comprising a base 4 supporting an arm 5. The two arms 5 of the dipole 2 define radiation lines. To increase gain and bandwidth, another radiation line is added on top of this radiation line, which is formed by parasitic or "director" elements 6 that are not electrically connected to the dipoles 2 . The dipole 2 is fed by a wire 7 connected to a balun, which is not shown in the figure. The strip dipole 2 and parasitic element 6 are printed with low dielectric constant ε rr (1rr figure 1 b), the substrate is, for example, a Teflon and glass plate from the company "TACONIC" with the product code "TLX-08". The wires 7 are printed on the reverse side of the dielectric substrate 8 ( figure 1 c).
