Estimation of 433 MHz path loss in algae culture for biosensor capsule application

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...

Description
Summary: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.
