“…However, at radio frequencies it is usually assumed that the random noise of an antenna will be as low or lower than the thermal noise corresponding to room temperature [9]. The antenna noise can thus be modeled as V 2 n,A = 4kT R A ∆f , where k = 1.38 · 10 −23 J/K is Boltzmann's constant, T = 300 K, and ∆f denotes the unit bandwidth.…”

The aim of this brief is to point out the importance of co-designing electrically-short antenna-electronics interfaces as a way to improve the system performance. This can be achieved if both the antenna and electronic circuit designer have a common optimization target. In this brief, the co-design principles are presented for antenna systems in the receiving mode, which includes reception of wireless information and wireless power. A general interface analysis is carried out, suggesting that the choice of interface impedance plays a crucial role in the optimization procedure and depends on the preferred signal quantity of the electronic circuit. This allows to effectively improve design criteria such as noise figure, power efficiency and sensitivity without increasing the power consumption. Finally, two examples are treated to demonstrate the antenna-electronics co-design for the reception of wireless information (LNA) and wireless power (RF energy harvesting).
