Modelling receiver and transmitter antennas for "Landish" capsule endoscopic complex
This paper deals with the modelling of different options of the antenna system of the "Landish" wireless capsule endoscopic complex including: an antenna for the reader (receiver antenna) and an antenna for the capsule endoscope (transmitter antenna). The patch antenna is considered for the receiver and 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 receiving and 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.
