Abstract

A new omnidirectional printed planar microstrip antenna is described. The radiation pattern of this antenna is analyzed numerically with the finite-difference time-domain (FDTD) method and compared with measurement. The length of the antenna can be scaled to increase or decrease gain. The driving point is unbalanced and may be fed directly with a coaxial cable. The impedance at the driving point of the antenna can be varied by adjusting the width of the radiating elements W₂ to provide a match.
