Dielectric Cap Loading Technique for Improving the Antenna Element Performance

In this letter, a dielectric cap loading technique for improving the performance of dipole and loop elements is introduced. Traditionally, dielectric loading is considered a destructive method leading to increased antenna Q -values. However, in this letter, the dielectric loading is exploited to increase the antenna space capacitance, leading to performance enhancement and lower Q -values. The technique is realizable with 3-D dielectric (ceramic) blocks.
