✦ Synopsis

The direct integration of an antenna on a system board of antennas is a promising technique for telecommunication network systems. This concept extends from pre¨ious studies on surface-mounted antennas and printed dipole excitation, allowing lighter manufacturing and trimming phases than classical methods, and keeping the o¨erall performance. This paper presents experimental results of low-profile, low-cost, and directly stacked antennas. These results are all the more interesting as it is possible to ha¨e all of the circuitry on the same printed board side as the antenna. Radiation pattern and matching results are also gi¨en for DECT and DCS applications. A 5.5% working bandwidth has been obtained around 1.8 GHz for a matching better than 6 dB and an omnidirectional radiation pattern.
