dc.descriptionThe invention consists of a dual band printed antenna planned to be implemented preferably in base stations of dual mobile telephony which use GSM and DCS-1800 systems, although other applications are not rejected.Similarly to the well-known printed antennas, the invented antenna has a dielectric substrate layer whose front side presents a printed patch. This patch is fed by the conventional microstrip line technique that is why the front side presents a microstrip line stretch reaching the patch. The dielectric layer’s backside presents an electric Earth reference. So far, this structure corresponds to the known as ‘printed antennas’.Optionally, the dielectric layer’s backside can include a metallic strip that will facilitate the adjustment corresponding to the bandwidth. The antenna’s microstrip line and the Earth reference can be connected to a SMA connector in order to facilitate feeding. This Earth reference, according to a preferential performance, has the same length as the microstrip line. In other performances, this reference could be placed perpendicular to the radiating patch enabling an omnidirectional configuration of the antenna. Depending on different performances and the sought radiation patterns, the dielectric layer’s backside could have a metallic plug joint to the Earth reference and/or a PTFE element (polytetrafluoroethylene, commonly known as Teflon). In that case, the PYFE element position has been planned to be either following the plug or between the plug and the Earth reference.es
dc.description.abstractThe antenna has a dielectric substrate layer whose front side presents a patch antenna fed by a microstrip line stretch and whose back side presents an Earth reference. This patch has the shape of an isosceles triangle which connects one vertex to the stretch, while in parallel to the opposite side of the vertex, there is a slot in the patch operating like a filter. This enables a dual band operation wherein two resonant frequencies are controlled by the variation of the patch size and the slot length. The frequencies can be adjusted to values of 900 and 1800 MHz, facilitating the application of the antenna in dual mobile telephony with GSM and DCS-1800 systems. With this technological offer we try to collaborate with licence agreement and commercial agreement with technical assistance.es
