Vespa Velutina is an invasive species of hornet posing a threat to European bees and the native European ecosystem. To deal with the problem, a lightweight transmitter has been designed, along with an automatic direction finding receiver algorithm. This report focuses on the work of the "transmission and reception of an ultra-low power signal" subgroup, namely the signal, antenna and amplifier designs. This part of the project ensures that the available ultra-low power signal sent out by the transmitter reaches the receiver with maximum feasible efficiency.
