Abstract (en)

[origin: EP0805512A1] The antenna has a conductive deposit (30) on one face of a dielectric sheet. The other face is covered by an earth plane. Four radial slots (31-34) are spaced at 90 degrees intervals around the circumference of the sheet to determine resonant frequency of a selected higher mode. The fundamental mode gives a radiation pattern with a maximum at right angles to the plane of the element. In the higher (TM21,TM01) mode, the current flow at right angles to the slots. The lengths (Lo) and widths (La) of the slots are preferably computed by finite element analysis software.
