Abstract

This paper presents numerical analyses of a plasma‐column antenna using the finite‐difference time‐domain (FDTD) technique. We have simulated simple plasma‐antenna configurations (monopoles) to demonstrate some of their properties. We have evaluated the field distribution around the plasma antenna, current distribution along the plasma column, radiated power, antenna pattern, and antenna impedance of the plasma column antenna. It has been demonstrated that the plasma antenna can operate with characteristics similar to a copper antenna. Furthermore, the alteration of the plasma properties enables the dynamic reconfiguration of the plasma antenna. © 2005 Wiley Periodicals, Inc.

## Abstract A printed meander antenna is studied using the FDTD method. The influence of a number of antenna parameters (dielectric constant, substrate thickness, and presence of ground plane) on the input impedance and radiation pattern of the antenna is examined. It is found that a 60% size reduc
