I'm curious about anyone that has concrete hands on experience tinkering with very small low frequency antennas.
My band of interest is 6, 13 or 27 MHz.
I wonder if it is possible to design a very small physical antenna that will radiate with some directivity even if the efficiency is not so good? This is an ISM band investigation. What good is an idea for an ISM band widget if the antenna has to be the size of a house?
I'm not interested in long range communications or high power but the ability to fill a room, rooms or the floor of a house with the maximum permissible SAR allowed by the FCC for tracking objects with transponders attached. Many thanks.
