    Abstract: Sistema (50, 60), que comprende: una antena (34, 71, 72); un primer circuito (51, 55, 61, 65) que puede hacerse funcionar para proporcionar una primera señal a dicha antena; un segundo circuito (52, 56, 63, 67) que puede hacerse funcionar para proporcionar una segunda señal a dicha antena, estando la segunda señal desfasada en frecuencia con respecto a la primera señal; y en el que dicha antena puede hacerse funcionar para transmitir un primer haz correspondiente a la primera señal con una primera polarización, dicha antena puede hacerse funcionar además para transmitir un segundo haz correspondiente a la segunda señal con una segunda polarización que es ortogonal a la primera polarización, y en el que dicho segundo haz solapado parcialmente se solapa al primer haz y está desfasado en frecuencia con respecto al primer haz para minimizar de ese modo la formación de puntos nulos en el primer haz y el segundo haz.

    Abstract: A wireless system, which minimizes nulls within the wireless system, while simultaneously providing diversity. A wireless system will now have increased capacity and coverage due to an enhanced signal to interference ratio in the areas of beam overlap. The system uses time or frequency offset on the signals input to an antenna to minimize interference in the regions of beam overlap. Additionally, polarization diversity can be introduced using Butler Matrices in conjunction with array elements to enhance the interference reduction.

    Abstract: A wireless system (30) minimizes nulls within the wireless system while simultaneously providing diversity. The system uses time or frequency offset on signals input to an antenna (40, 50, 60, 100) to minimize interference in regions of beam overlap. Additionally, polarization diversity can be introduced using Butler Matrices (69, 70) in conjunction with array elements (102-128) to enhance the interference reduction. As a result, the wireless system has increased capacity and coverage due to an enhanced signal to interference ratio in the areas of beam overlap (O1-O3).

    Abstract translation: 无线系统（30）最小化无线系统内的空值，同时提供分集。 该系统对输入到天线（40,50,60,100）的信号使用时间或频率偏移来最小化波束重叠区域中的干扰。 另外，可以使用Butler矩阵（69,70）与阵列元件（102-128）一起引入极化分集，以增强干扰减小。 结果，无线系统由于在光束重叠（O1-O3）的区域中的增强的信号与干扰比而具有增加的容量和覆盖。
