In this paper, application of a designed antenna for microwave imaging is evaluated. In previous research, application of an UWB antenna for microwave imaging was investigated. To the best of the author’s knowledge, the designed antenna was the smallest UWB antenna designed at the time of publication, for breast cancer detection. The smaller size antennas can cause more clutter in the image while, on the other hand, make it possible to use more antennas in the array at the same surface. Therefore, the smaller size of the antenna makes microwave imaging more challenging. Simulation results showed successful detection of 10 mm and 5 mm tumors by 16 UWB antennas with the hemispherical arrangement. For signal processing, the Delay-Multiply-and-Sum Algorithm is used for image reconstruction. In this paper results of two experimental microwave imaging is presented. Two tumors at different locations are placed and microwave imaging is performed. The experimental proves that the designed antenna in an array of 16 antennas is capable of detecting the 5 mm tumor in different location.

在本文中，评估了设计的天线在微波成像中的应用。在先前的研究中，研究了超宽带天线在微波成像中的应用。据作者所知，设计的天线是出版时设计用于乳腺癌检测的最小的UWB天线。较小尺寸的天线会在图像中引起更多混乱，而另一方面，可以在同一表面上使用阵列中的更多天线。因此，天线的较小尺寸使微波成像更具挑战性。仿真结果表明，通过半球形排列的16个UWB天线成功检测到10毫米和5毫米肿瘤。对于信号处理，使用“延迟与和”算法进行图像重建。本文介绍了两个实验微波成像的结果。放置两个位于不同位置的肿瘤，并进行微波成像。实验证明，在16个天线阵列中设计的天线能够在不同位置检测到5毫米肿瘤。
