ABSTRACT:
A miniature vertically polarized multi-frequency antenna10is embedded in a substrate11and suitable for use within a wireless device. The antenna10includes a first lateral member14and a second lateral member16, which is spaced from and parallel to the first lateral member14. The antenna10has a wide tuning range due to multiple resonances provided by the lateral members14, 16. The antenna10is shortened by reactive loading and by embedding the antenna in material having a high dielectric constant. Tuning circuits30, 32are coupled to respective ends of one of the lateral members14, 16. The tuning circuits are located on a common plane with the lateral member to which they are connected. The tuning circuits30, 32electronically add reactance to the antenna to alter the frequency at which it resonates. A method of providing the antenna10includes forming flat metal strips14, 16on layers of a laminated substrate11and forming the second lateral member16between adjacent layers20, 22of the substrate11.
