The equivalent circuits are realized for the conical monopole antenna with split loops.
The geometry and dimensions of the conical monopole antenna for UWB are depicted in Figure 1.
As the length of the conical monopole antenna increases, the input impedance converges to the characteristic impedance of a spherical coaxial transmission line.
The dimensions of the conical monopole antenna are identical to the dimensions of Figure 1.
The transmission line in Figure 7 corresponds to the conical monopole antenna. Because the magnetic field of the antenna passes through the split loop, mutual inductance exists between the two components.
M that appeared in (6a) and (7) represents the mutual inductance between the conical monopole antenna and the split loop.
