宽槽UWB天线的检测计划正在开发中的布里斯托大学的基础上，使用一个完全填充的静态阵列的合成聚焦UWB雷达的原理。天线的测量和模拟，输入和辐射特性，并比较现有的，堆叠贴片天线，已被设计用于相同的目的。研究结果表明，宽缝隙天线在所需的频率范围内具有优异的性能。与我们之前阵列中使用的堆叠贴片天线相比，宽槽天线可以小3倍（就前表面而言）。缝隙天线的紧凑性质意味着检测阵列可以密集地填充。此外，这种新的天线提供了更好的乳房辐射覆盖。对于角度高达60远离膛瞄准器辐射脉冲几乎是相同的（保真度>95%），而对于贴片天线保真度福尔斯下降到58%，在角度的极端。进入乳房的均匀辐射应导致具有低水平杂波的聚焦图像。
A wide-slot UWB antenna is presented for intended use in the detection scheme being developed at the University of Bristol, based on the principle of synthetically focused UWB radar using a fully populated static array. The antenna's measured and simulated, input and radiation characteristics are presented and compared to an existing, stacked patch antenna that has been designed for the same purpose. The results of this study show that the wide-slot antenna has excellent performance across the required frequency range. Compared to the stacked-patch antenna used in our previous array, the wide-slot antenna can be 3 times smaller (in terms of front surface). The compact nature of the slot antenna means that the detection array can be densely populated. Additionally, this new antenna offers better radiation coverage of the breast. For angles up to 60 away from bore-sight radiated pulses are almost identical (fidelity >95%), whereas for the patch antenna fidelity falls to 58% at the angular extremes. This uniform radiation into the breast should result in focused images with low levels of clutter.
