Modeling of Antenna System for Capsule Endoscopic Complex “Landish”

This article focuses on modeling of different options of antenna system including and in particular an antenna for the capsule endoscope (transmitter antenna) of the capsule endoscopic complex “Landish”. A helical antenna is reviewed for the transmitter, as well as a patch antenna on a curved substrate, and a quarter-wave monopole vibrator and a ceramic antenna. An experiment was conducted in order to compare the gain of the antennas at a fixed position in the space of the transmitting antennas, and the impact of the human body on the features of antennas. Recommendations on the choice of antenna systems in accordance with the simulation results are provided.
