Antennas: Cavity-Backed Slot Antennas - Antenna Theory A practical slot antenna is the cavity-backed slot antenna. Unfortunately, the equations related to the cavity backed slot antenna are somewhat complicated and in my opinion don't give a good idea of how they work. Hence, I'll present the basics, present Modal Resistance of Spiral Antenna antenna topologies where wire width can no longer be considered negligible, the current distribution will reside on the edge of the conductor and the power will radiated when the two neighboring current distributions are in- phase. This leads to the concept of 2-Arm Conical Spiral Antenna - superkuh
