Abstract

Cancer is one of the leading causes of death worldwide. Early detection is the best solution for cancer treatment. The UWB microwave imaging technology is one of the most promising technologies in the field of medical diagnosis, because it is non-ionizing and low cost. One of the most important elements in a microwave imaging system is an antenna. Recently, the flexible electronic is used as substrate for microstrip antenna. This paper will proposed the design of flexible antenna for breast tumor detection. The proposed antena is designed using Polyethylene Terephthalate (PET) as substrate and silver as patch. The simulation result shows flexible antenna is work at 5.8 GHz frequency with -25.27 dB value of return loss, 1.115 value of VSWR, 3.37 GHz bandwidth, 58.1% GHz impedance bandwidth and 2.68 dBi Gain. By using a flexible substrate, the antenna can follow the structure of the breast and can be placed in the breast for better breast tumor detection.

Abstract

Current technological advances and developments require the academic community to continue to innovate to build the country by improving science and technology. One area of concern for researchers is Electronics and Telecommunications. Part of the science that is currently quite indemand is the antenna. In this study discusses Stretchable Antenna Simulation Modeling for RADAR Applications, the antenna is designed using Polydimethysiloxane (PDMS) material so that theantenna can be bent and adjusted to its placement. The antenna is made with an Ultra Wideband (UWB) frequency in the frequency range of 3.1 – 10.6 Ghz with a minimum bandwidth of > 500 MHz and a return loss of < -10 dB with a VSWR of < 2, so that the antenna can detect according to radar capabilities because this frequency has wide bandwidth. When this antenna is simulated the antenna can work at a center frequency of 3.4 GHz with a bandwidth of > 500 MHz, then when the antenna is bent it does not experience a significant change in frequency, judging from the bandwidth obtained is the same but the return loss is getting lower to -43 dB but still at a frequency of 3.4 GHz.Keywords: Antena, Polydimethylsiloxane (PDMS), AgNw, Stretchable, Bending, RADAR, Ultra Wideband (UWB).

Abstract

Microwave imaging system is one of the technologies that can be used to detect objects, especially in the field of medical diagnoses, such as detecting tumors in the breast. The technology used is ultrawideband (UWB) with the advantages of low cost, low power consumption, and high transmission capacity. In this study, a flexible antenna was designed at a frequency of 5.8 GHz using a polydimethylsiloxane (PDMS) substrate with a dielectric constant of 2.67 – 3.00 and a loss tangent of 0.02-0.05 for breast tumor detection applications. The antenna design process uses the CST studio suite software. The simulation results of a flexible antenna at an operating frequency of 5.8 GHz with a return loss parameter of -39.19 dB, a VSWR of 1.22, a bandwidth of 3.1 GHz in a frequency range of 4.52–7.62 GHz, the resulting radiation pattern is almost omnidirectional, and a gain of 2.26 dBi. In addition, the gain of flexible antenna with phantom breast without tumor is -23.62 dB and phantom breast with tumor is -24.85 dB at operating frequency of 5.5 GHz, which is shifted by 300 MHz from the desired frequency. Keywords: microwave, ultra-wideband (UWB), flexible antenna, polydimethylsiloxane (PDMS)
