Breast cancer is a medical condition characterized by the uncontrolled proliferation of cells in the breast tissue. Breast cancer can originate from various parts of the breast, and methods such as Breast ultrasound, Diagnostic mammogram, Breast magnetic resonance imaging, and Biopsy are currently used for its diagnosis. However, these methods have certain limitations, and their size can be a hindrance. To overcome this, low-power, flexible antennas can be designed for bio-communication between medical equipment and external instrumentation. Flexible and wearable antennas have advantages such as affordability, ease of fabrication, and high gain. In this article, a microstrip patch antenna operating at 2.45 GHz and made of polyamide material is designed using High Frequency Structure Simulator software. The simulation results show the patch antenna has a gain of 1, −14.81 dB return loss at 2.45 GHz based on |S11| ≤ −10 dB. The directive radiation pattern with axial ratio of 63.39 dB and voltage standing wave ratio ≤3. Furthermore, the hardware development of proposed antenna with polyamide substrate provides the resonance frequency nearing to simulation results as 2.318 GHz with return loss of −28.19 dB. Based on mathematical analysis, simulation and hardware results, the proposed antenna is a superior option for breast cancer detection.

“…It can potentially transform the world of work, the global economy, and people's lives. (3,4) Due to contagious diseases and serious pandemics that have weakened the healthcare system and direct patient diagnosis in recent years, an alternative solution is needed. Telemedicine is one of the components of medicine that transmits medical data by means of electronic devices.…”

La tecnología de la telemedicina es uno de los principales logros de los últimos años. Esta tecnología se basa en dispositivos biomédicos que contienen componentes esenciales, entre ellos las antenas. Las antenas biomédicas garantizan el intercambio de datos entre los dispositivos instalados en el cuerpo humano y el entorno exterior. Este artículo presenta el estudio y diseño de una antena de parche circular flexible implantada en un sustrato de origen biológico para aplicaciones industriales, científicas y médicas. La frecuencia elegida para el estudio es de 2,45 GHz. Mediciones de pérdidas de retorno y diagrama de radiación. En este estudio también se investiga una mejora en la ganancia de esta antena. Esta antena ofrece unas prestaciones adecuadas para satisfacer las necesidades de los usuarios 5G. Esta antena está impresa en un sustrato de poliéster con un espesor de h=2,85cm, una permitividad relativa εr=3,2, una tangente de pérdida igual a 0,003, y un radio de parche igual a 2,11cm. Además, esta antena proporciona los siguientes resultados: coeficiente de reflexión S11=-26,59dB, ancho de banda BW=0,12GHz, ganancia G=5,6, directividad D=5,8dB, y eficiencia η=96,55%.
