Fig. 14From: Leveraging discrete modulation and liquid metal antennas for interference reductionGap to capacity. The plot shows the ratio of achievable rate to capacity for different channel coefficients (i.e., due to a change in the geometry of the setup in Fig. 7). From top to bottom, the curves represent the maximum, average, and minimum performance for all states in \({\mathcal{S}}_d^{\prime}\) of the liquid metal antenna of Fig. 8Back to article page
