“…In radar-based microwave imaging based on the strong scattered waves, tumor is detected. There are several researches using this method for breast cancer detection [19][20][21][22][23][24][25][26]. Based on the design, patient lies on supine or prone position and an antenna array locates on the breast.…”

Basis of the microwave imaging is the contrast in dielectric properties of breast normal tissue and tumor. Confocal microwave imaging involves transmitting an ultrawideband signal through number of antennas and records the scattered signals. Then by synthetically focusing reflections from the breast, we can make image from breast. In this article, we demonstrate the feasibility of detecting 10-and 5-mm tumors in three dimensions with different antenna arrangements with different number of antennas. Two models of hemispherical array are presented. An image formation algorithm is presented for 3D image making. Successful detection of 10-and 5-mm tumors are achieved with the hemispherical arrangement. The influences of the different breast sizes for tumor detection are also explored.

“…To gather sufficient information for good image quality, the antenna design is a vital part, as the antennas must be able to operate over a wide band of frequencies and also be as small as possible so that the enough number of antennas can be arranged on the surface of the breast. In this work, a slot on-body antenna whose detail design is reported in [8] has been employed as a good candidate. During this detection, a Gaussian pulse is emitted from one antenna alternately and the backscattered signals are received by the other antennas.…”

Ultra wide-band (UWB) microwave imaging technique is very promising in detecting the early breast cancer. In previous studies, the tumor-free model was always needed to help extract the calibration waveform, which cannot be obtained directly in the real clinical detection. In this paper, to solve this problem, a novel signal processing method based on ensemble empirical mode decomposition (EEMD) is proposed to extract the tumor response. This approach is crucial to extract the tumor response directly from the detected signals in the actual clinical diagnosis, as it does not need the tumor-free model at all. The feasibility of using this method to extract the tumor response signal without the tumor-free model is explained in the reconstructed breast image, which shows the correct tumor information.

“…It can achieve high gain without compromising the size. Numerous antennas are designed over time for breast phantom imaging, such as pyramidal horn antenna, 2 the Vivaldi antenna, [3][4][5] CPW antenna, 6 EBG antenna and metamaterials, 7 array antenna, 8 and the slotted antenna. [9][10][11][12] The main difficulty of designing an antipodal Vivaldi antenna is to get a directive radiation pattern and a lower frequency band resonance with compact dimension.…”

In this article, an improved method is introduced for enhancing the gain and directivity of a modified antipodal Vivaldi antenna, which is suitable for detecting malignant cells in the breast through microwave imaging. By slotting on the fins of the antenna with the addition of parasitic elliptical patch makes the antenna radiation more directive with more gain at the lower band range. The operating fractional bandwidth of this proposed Vivaldi antenna is 120% (2.50‐11 GHz) with compact dimension and directive radiation pattern with 7.20 dBi highest gain. The antenna time‐domain performance and the near‐field directivity (NFD) are also observed. Effective microwave breast phantom imaging system with an array of 16 antipodal antennas is designed where one antenna works as a transmitter and rest of the antenna works as a receiver in turn. The imaging performance is investigated with tumor inside the breast phantom using the Microwave Radar‐Based Imaging Toolbox open source software. Detection of tumor tissue inside breast phantom has been identified by analyzing the modified antipodal Vivaldi antennas' backscattered signal.
