A note on the imperfectly conducting circular‐loop antenna

The thin‐wire circular‐loop antenna with a distributed impedance loading is analyzed by a simple extension of the Fourier series solution for the perfectly conducting loop antenna. When the loading is a uniform resistance per unit length, the solution obtained is that for the imperfectly conducting loop. The broadband characteristics of the imperfectly conducting loop are examined. Impedances calculated by the Fourier series method are compared with those calculated by Lin [1973] using numerical and differential equation methods. In addition, the effects of the resistive loading on the radiating efficiency and the far‐zone field pattern are investigated.
