Now-a-days, the uses of antenna based devices are rapidly increasing. Among those antenna based devices mobile phones and Wi-Fi routers are the important modules which play the crucial role in every individual’s life. As the technologies & usage of it are rapidly increasing and to meet the satisfaction of the end users all the providers are looking to elaborate their signal strength and other parameters. So, as to increase the strength of the signal the antennas should be capable of meeting it. In this paper, we would like to present the Microstrip patch antenna design of parasitic slot structure with an operating frequency of 7.5 GHZ and comparison of some their parameters with the other antenna structures. For this design, we use high frequency simulation structure (HFSS) software; the antenna is based on the FR4_epoxy substrate with tangent lass of 0.0018 and dielectric constant of 4.4(approx.). After simulation, the performance characteristics such as return loss (S11), gain, directivity, radiation pattern, VSWR are recorded and compared also.

Fetal monitoring during pregnancy time is the most important to save the life of the mother as well as the child. In this paper, we present a device that is used to measure the fetal heart rate during the time of pregnancy. The major component used for this detection is Fetal Digital stethoscope sensor which is to be placed on the abdomen of the pregnant and the signals are processed by the micro-controller used and the accurate fetal heart rate is identified and sent as a text message to the respective mobile phone through the usage of GSM module and also by the usage of EMG sensor the uterus contraction also be simulated as the output on the desktop. This system is very flexible and low cost helps the patient to monitor the fetal heart rate in home
