Abstract
This paper presents the path loss estimation for 433 MHz waves transmitted from inside an algae culture. Investigations were performed as preliminary consideration for a biochemical sensor capsule application. It was found that the path loss in distilled water on average was 15 dB higher than in air. The path loss in algae was 6 dB higher than in water. The differences were caused by a mismatch of the transmit antenna surrounded by a liquid medium.
