Found this article today about miniaturizing antenna using acoustic resonance. What military applications will this have, is this going to greatly reduce radar equipment weight in the future?

State-of-the-art compact antennas rely on electromagnetic wave resonance, which leads to antenna sizes that are comparable to the electromagnetic wavelength. As a result, antennas typically have a size greater than one-tenth of the wavelength, and further miniaturization of antennas has been an open challenge for decades. Here we report on acoustically actuated nanomechanical magnetoelectric (ME) antennas with a suspended ferromagnetic/piezoelectric thin-film heterostructure. These ME antennas receive and transmit electromagnetic waves through the ME effect at their acoustic resonance frequencies. The bulk acoustic waves in ME antennas stimulate magnetization oscillations of the ferromagnetic thin film, which results in the radiation of electromagnetic waves. Vice versa, these antennas sense the magnetic fields of electromagnetic waves, giving a piezoelectric voltage output. The ME antennas (with sizes as small as one-thousandth of a wavelength) demonstrates 1–2 orders of magnitude miniaturization over state-of-the-art compact antennas without performance degradation. These ME antennas have potential implications for portable wireless communication systems.

For most army radios (RTO guy in a platoon size element) the heaviest part is usually the battery pack or rechargeable pack depending on the types of course. The antenna's are usually bendable piece of metal that are light.

In my old days the US Army used to carry the PRC 25 Radio in your ruck sack and with an extra battery as well if your lucky to become the RTO.;) It was quite heavy and the batter doesn't last very long. You get less room in your ruck sack to store your bullets, gears, and MREs.

Use lug this bad boy here with the exact same kind of M-16A1 rifle and BDU camos and cap.
