The proposed antenna belongs to the area of integrated antennas with optimum features, and it is materialised in a metallic patch parallel to a Earth reference. The patch is preferably a rectangle but it can also have a trapezoidal shape, incorporating an only feeding pin and a short circuit which connect the antenna to the Earth reference.The antenna is approximately as long as a quarter of the highest resonance frequency’s wavelength, while the lowest resonance frequency is determined by a band-stop filter called spur-line, parallel to three out of four sides of the patch.The fact that the short circuit is placed in the furthest area from the slot or spur-line along the perimeter let us obtain a second resonance at a lower frequency than the original patch’s resonant frequency.
The antenna has a metallic rectangular patch placed in a plane parallel to the Earth reference, which it is connected to by a metallic pin that acts as feeding point and another one as a short circuit. The patch is approximately as long as a quarter of the highest resonant frequency’s wavelength. The lowest resonant frequency is obtained from a spur band-stop filter parallel to three out of four sides of the patch.With this technological offer we try to collaborate with licence agreement and comercial agreement with technical assistance.
