Development and validation of a low‐frequency modeling code for high‐moment transmitter rod antennas

Abstract: [1] The goal of this research is to develop and validate a low-frequency modeling code for high-moment transmitter rod antennas to aid in the design of future low-frequency TX antennas with high magnetic moments. To accomplish this goal, a quasi-static modeling algorithm was developed to simulate finite-length, permeable-core, rod antennas. This quasi-static analysis is applicable for low frequencies where eddy currents are negligible, and it can handle solid or hollow cores with winding insulation thickness b… Show more

“…Here we determine the effects of scaling all physical dimensions of the rod antenna by a factor p, except for the cross-sectional area of the individual wires or strips that are used to construct the core. Since the complex permeability and electrical conductivity vary with frequency, we will use the same frequency for the rods by using the simple and analytical expressions for an air-core antenna and expressions that were derived in the prolate spheroidal analysis [Jordan, 2008]. From this, we found the modified scaling factors for air-core and rod-core antennas that are shown in Table 1.…”

“…The trade off for using more turns and less drive current to reach the desired magnetic flux density is an increase in both inductance and core series loss resistance by a factor of N 2 . Refer to Jordan (2008) to see this N turns 2 dependence and the direct tradeoff between the current and the number of turns which was obtained by investigating the tangential magnetic field coefficients in the prolate spheroidal series expansions.…”
