Perancangan Biosensor Invasif Antena Untuk Deteksi Viskositas Cairan Sperma
One of the declines in health in the two decades is the decline in fertility rates. The most serious is the decline in fertility rates in men. Research has shown that environmental and lifestyle factors such as consuming alcohol and cigarettes affect the level of sperm (semen) quality. In this research, an antenna biosensor was designed to detect male fertility which is proposed to operate in the 2.4 GHz frequency range according to Industrial Scientific and Medical (ISM) standards for biomedical applications (Salim et al., 2018). The proposed antenna design uses Fr-4 substrate material with a thickness of 1.6 mm and dimensions of 50 mm x 50 mm. In this research, the antenna design was designed using microstrip line and Defected Ground Structure (DGS) feeding techniques. The circular antenna patch uses copper material with a thickness of 0.035 mm. Patch and ground designs are on one side of the surface and back. The antenna design proposed in this research focuses on a simple and low cost design. Testing in this study used sperm samples using the dilution method or sperm dilution method using Mcfarland standards. The dilution method was carried out 5 times, then each sample was measured using an antenna and the frequency shift was seen, where the data obtained showed that there was a decrease in frequency according to the intensity of the number of dilutions carried out, this proves that there has been a shift in frequency caused by the intensity of the sperm in the test solution. where the fewer sperm in the solution, the frequency test results are found to decrease.
