An enna Constants

Abstract

After introducing the theory of antenna circuit having uniformly distri uted constants, such as inductance, capacitance, and resistance; and shows the fact that an antenna circuit can exactly represented by equivalent circuit which a closed oscillation circuit carrying uniform current, deriv ng from the Maxwell-Lagrange equation.
Equivalent constants, and especially natrral frequency of an antenna circuit is introduced and sows that the frequency can be calcuable either equivalent constants of antenna circuit and thomson's formula
f=1/2π√C_eL_e, or staic constants of antenna circuit and the equation
tanω√C_AL_A=√L_A/C_A/ωL_θ-1/ωC_θwith graph
where C_e, C_A=equivalent and static capacity
L_e, L_A=equivalent inductance and static inductance
L₀, C₀=loaded inductance and capacity at the base of antenna
ω=2πf
f=natural frequency of antenna.
