By invoking the inverse-sequare law, you are doing a couple things that are incorrect simultaneously. First, you are assuming a false equivalence between a beamforming antenna that sends concentrated, coherent beams of RF at a single target with an ordinary antenna that radiates energy isotropically. Second, you are also assuming that the power density of the system must be high in order to bring about any physiological effects. This is not necessarily true. It may be the case that self-assembling nanotransducers surreptitiously placed in the brain may only need to harvest nanowatts to induce profound changes in neuronal activity. The amount of energy that actually reaches them could be very small, and yet still achieve the desired effect.
LOL it's my fault now for "assuming"... how about you post something coherent beyond "may", "could", and vaguely relevant speculation. What is "high" power density? How much does your imaginary self-assembling 5G receiver need? How much does the brain-prodding thing need? How much power can the hypothetical magical physics-defying antenna harvest? Does this involve some energy storage for when I go to my basement and out of 5G signal range, or do I just snap out of the mind control thing then? "nanowatts" (better than -60 dBm) is extremely optimistic, in reality you'd be dealing with picowatts if that.

Just a little back of the envelope (or HP-48 emulator) scratching, with 2000 Kcal/day at 25% allocated to the brain, and about 100X10^9 neurons, the natural energy budget is about 0.000005 cal per neuron per day. With that they must both operate their normal celular biological process and generate electrical energy for signaling. Noting that a) the various talk, RFQ, etc were pretty much centered around a per-neuron interface, and b) a capacitor is probably one of the easier components to assemble, it seems like energy acquisition at sufficient power levels (voltages and currents) would be among the lesser of the problems. I would think it more likely to be done by taping biological structures which already maintain a potential (mitochondria, other neurons, etc) for the most part anyway.
500 kilocalories / 100 billion neurons = 0.02 millijoules per day to run one neuron.
0.02 millijoules per day is 231 picojoules per second.
The amount of absorbed power needed for one nanoparticle to manipulate one neuron is extremely minute.

https://pubmed.ncbi.nlm.nih.gov/32160534/One approach to magnetogenetics uses radiofrequency (RF) waves to activate transient receptor potential channels (TRPV1 and TRPV4) that are coupled to cellular ferritins. The mechanisms underlying this effect are unclear and controversial. Theoretical calculations suggest that the heat produced by RF fields is likely orders of magnitude weaker than needed for channel activation. Using the FeRIC (Ferritin iron Redistribution to Ion Channels) system, we have uncovered a mechanism of activation of ferritin-tagged channels via a biochemical pathway initiated by RF disturbance of ferritin and mediated by ferritin-associated iron. We show that, in cells expressing TRPVFeRIC channels, RF increases the levels of the labile iron pool in a ferritin-dependent manner. Free iron participates in chemical reactions, producing reactive oxygen species and oxidized lipids that ultimately activate the TRPVFeRIC channels. This biochemical pathway predicts a similar RF-induced activation of other lipid-sensitive TRP channels and may guide future magnetogenetic designs.

https://www.emfanalysis.com/wp-content/uploads/2015/06/EMF-Effects-via-Voltage-Gated-Calcium-Channels-Dr-Martin-Pall.pdfThe direct targets of extremely low and microwave frequency range electromagnetic fields (EMFs) in producing non-thermal effects have not been clearly established. However, studies in the literature, reviewed here, provide substantial support for such direct targets. Twenty-three studies have shown that voltage-gated calcium channels (VGCCs) produce these and other EMF effects, such that the L-type or other VGCC blockers block or greatly lower diverse EMF effects. Furthermore, the voltage-gated properties of these channels may provide biophysically plausible mechanisms for EMF biological effects. Downstream responses of such EMF exposures may be mediated through Ca2+/calmodulin stimulation of nitric oxide synthesis. Potentially, physiological/therapeutic responses may be largely as a result of nitric oxide-cGMP-protein kinase G pathway stimulation. A well-studied example of such an apparent therapeutic response, EMF stimulation of bone growth, appears to work along this pathway. However, pathophysiological responses to EMFs may be as a result of nitric oxide-peroxynitrite-oxidative stress path- way of action. A single such well-documented example, EMF induction of DNA single-strand breaks in cells, as measured by alkaline comet assays, is reviewed here. Such single-strand breaks are known to be produced through the action of this pathway. Data on the mechanism of EMF induction of such breaks are limited; what data are available support this proposed mechanism. Other Ca2+-mediated regulatory changes, independent of nitric oxide, may also have roles. This article reviews, then, a substantially supported set of targets, VGCCs, whose stimulation produces non-thermal EMF responses by humans/higher animals with downstream effects involving Ca2+/calmodulin-dependent nitric oxide increases, which may explain therapeutic and pathophysiological effects.
If you read the Spartacus Letter, you might notice something. The onset of sepsis in COVID-19 is presaged by a sudden, uncontrolled rise in cytosolic calcium levels, associated with a profound hypocalcemia (i.e. calcium moving from the blood and into the intracellular space). The rise in cytosolic Ca2+ leads to ROS release, which leads to lipid peroxidation, which promotes an immune and complement cascade that destroys tissue.
I know this is going to be difficult to accept, but based on this information, it is entirely possible to trigger all of the symptoms of COVID-19 with nothing more than a maser of the right frequency. No virus required at all. Or, if there is a virus (based on the contagious spread and its prevalence in rural areas with no GSM infrastructure, this seems reasonable), it would enhance this process due to the shared etiology of disease, in the manner of a binary weapon.
