Abstract
In this paper, an effective system for microwave imaging of breast tumor detection using modified 16-planar log periodic antenna (PLPA) array is presented. The modified PLPA operates in the band from 2 to 5 GHz with stable directional patterns in the end-fire direction. Once the results of a single antenna element have been validated, the design is extended to include 16 antenna elements. All 16 transceiver antennas are vertically placed around the phantom in a circular manner where one antenna acts as a transmitter and the rest work as receivers. Delay and Sum (DAS) algorithm is used for post processing the acquired scattered signals from the sensors to reconstruct the image of the breast and to identify the existence of breast tumors. The electromagnetic simulators CST and HFSS are used to design the system, while MATLAB is used to process the data. The developed PLPA array-based microwave imaging system performs admirably, making it one of the most effective systems for detecting tumor cells.

Women die from breast cancer more often than any other cancer worldwide
As opposed to other medical imaging methods, microwave imaging is characterized by the fact that it is low in complexity, low in cost, and does not generate ionizing radiation
Very short microwave energy pulses are required in a near field wideband detection, which is an important requirement for medicinal applications involving electromagnetic fields [15]
Summary
Women die from breast cancer more often than any other cancer worldwide. Breast cancer develops in a very complex way, involving multiple cell types, and prevention of the disease remains a challenge. Very short microwave energy pulses are required in a near field wideband detection, which is an important requirement for medicinal applications involving electromagnetic fields [15] In this case, the planar log periodic antenna is a suitable candidate for MIS as it has high gain, low profile, wide bandwidth, and high directional patterns [16]. The sensors are controlled by a single-pole-eight-throw (SP8T) switching module, and the breast imaging is created by the DAS algorithm This system is very useful because it is portable; the design structure is complex, making it difficult to detect tumor. To make the use of this principle and apply it to a practical microwave imaging system for detecting tumors, an UWB pulse is sent to the suspected area of the target breast phantom using the prototyped transceiver antenna. Due to features, such as non-ionizing, less expensive, and no side effects, the proposed imaging technique can frequently be used to detect tumors in breast
