Abstract

The effect of the geometry of the equiangular spiral antenna on the lower cutoff frequency of operation is studied using the finite‐difference time‐domain method. Graphs are provided that allow calculation of the cutoff frequency from the desired performance and geometry. Additionally, the patterns of the antennas at cutoff are shown.

## Abstract The magnetic field distribution within a square spiral inductor is investigated in this paper by summing closed‐form expressions for the fields from each segment. Plots illustrating the variation of the normally directed **B**‐field penetrating the surface of the spiral traces are then
