ABSTRACT
This article focuses on technological developments in electronic antennas. More wireless designers now realize that the antenna holds the key to higher data rates, longer range, increased number of users per system, and greater reliability. Most antennas continue to be a passive collection of conductors optimized for the application. In many applications, commercial component antennas have replaced pc-board antennas. Commercial component antennas mount on the pc board like any other part. Dielectric antennas, a popular type of component antenna, employ conductors formed on a dielectric such as ceramic with a very high dielectric constant. The conductors use some variation of the dipole, inverted-F, patch, meander line, or other configuration. Others use a helical design. The ceramic dielectric usually narrows the bandwidth down to 5% to 8%. While such antennas work well, some are inefficient and usually introduce attenuation. But this loss often is traded off for ease of use and minimal detuning.
