The impedance characteristics of an L-shaped wire monopole antenna are experimentally in¨estigated. The effect of different ratios of the horizontal arm length to the height of the L-shaped monopole on the impedance characteristics is discussed. The in¨estigation demonstrates how a monopole with an

## Abstract In this paper, we present the design of an active integrated antenna (AIA) using a voltage‐controlled oscillator (VCO) for applications in the Industrial Scientific Medical (ISM) band (2.4 to 2.4835 GHz). The realized active circuit makes use of compact devices in surface‐mounting devic

## Abstract A new method of using artificial neural networks (ANNs) for the calculation of the input impedance of rectangular microstrip patch antennas has been adopted in this paper. The results obtained using ANNs are compared with the experimental findings, theoretical values, and with the simul
