Abstract

A Patch antenna is a kind of antenna with a low profile, which can be fixed on a surface. It communicates and gets electromagnetic waves inferred way. The boundaries of the antenna incorporate radiation design, gain, impedance, and frequency. Polydimethylsiloxane (PDMS) is utilized as a substrate in patch antennas. The existence of a tumor can be effectively recognized by the current density of the phantom. The difference in the current density value of phantom without tumor and with tumor shows the presence of the tumor. The first four antenna design shows a huge contrast in current density, the leftover two designs have little distinction of current density worth of phantoms. Six unique constructions of microstrip antenna are intended for skin tumor detection. In these six designs, the model for skin cancer recognition utilizing truncated corner, the working frequency is 2.492 GHz and S11 is –38 dB. The current density of the design relies on phantom characteristics. The acquired current density value of phantom without the growth of the tumor, with tumor, and with dangerous growth of the malignant tumor is (171.562, 193.381, and 204.199) A/m^2 and Specific Absorption Rate (SAR) value is (1.14049, 1.27013 and 1.26088) W/Kg respectively. Visible Light Communication (VLC) system using Orthogonal Frequency Division Multiplexing (OFDM) supports high-speed transmission. The effectively-identified tumor can be communicated through gadgets using Enhanced Reverse Polarity Optical OFDM (ERPO-OFDM) technique. It’s a multicarrier modulation that supports information transmission through Light Emitting Diodes (LEDs).
