Abstract

Translated fromPortuguese

Patente de Invenção: ANTENA UNIPLANAR DE DUAS FITAS. Uma antena uniplanar de fita dupla (400) que possui uma estrutura bidimensional. A antena é constituída por uma primeira e uma segunda fita metálica (404, 408), cada uma impressa ou gravada sobre um fino substrato plano (412). As primeira e segunda fitas (404, 408) estão separadas por uma fresta ou espaço (T) e são usadas como condutores de uma linha de transmissão de dois fios. Um guia de onda coplanar (416, 1520) está acoplado à antena uniplanar de fita dupla (400). O guia de onda coplanar (416, 1520) é produzido por impressão ou gravação de metal sobre o substrato. O terminal positivo (420, 1522) do guia de onda está eletricamente conectado à primeira fita. O terminal negativo (424, 428) do guia de onda está eletricamente conectado às primeira e segunda fitas. A antena uniplanar de fita dupla (400) de acordo com a presente invenção propicia um aumento na largura de banda em relação às típicas antenas de malha de um quarto de comprimento de onda ou meio comprimento de onda. Os resultados experimentais demonstraram que a antena uniplanar de fita dupla (400) possui uma largura de banda de aproximadamente 8 a 20 % que é extremamente desejável para telefones celulares e PCS.Invention Patent: TWO TAPE UNIPLANAR ANTENNA. A double-band uniplanar antenna (400) that has a two-dimensional structure. The antenna consists of a first and a second metallic ribbon (404, 408), each printed or engraved on a thin flat substrate (412). The first and second tapes (404, 408) are separated by a gap or space (T) and are used as conductors for a two-wire transmission line. A coplanar waveguide (416, 1520) is coupled to the double ribbon uniplanar antenna (400). The coplanar waveguide (416, 1520) is produced by printing or engraving metal on the substrate. The positive terminal (420, 1522) of the waveguide is electrically connected to the first strip. The negative terminal (424, 428) of the waveguide is electrically connected to the first and second tapes. The dual-band uniplanar antenna (400) according to the present invention provides an increase in bandwidth over typical quarter-wave or half-wavelength mesh antennas. The experimental results showed that the double-band uniplanar antenna (400) has a bandwidth of approximately 8 to 20% which is extremely desirable for cell phones and PCS.
