Abstract
The invention relates to a method for tuning dielectric antennas designed for operation especially in the microwave range, and an antenna structure. An antenna is tuned by removing material (211) from a dielectric block (210) located between conductive elements, whereby the resonance frequency of the antenna increases. The conductive elements (220, 230) on opposing surfaces of the dielectric block are advantageously shaped identical and located symmetrically with respect to each other so that the tuning of the antenna will not affect the other electrical characteristics of the antenna apart from the resonance frequency. With the method according to the invention there is no risk of producing conductive chips resulting from the working of metallic elements, the tuning of the antenna becomes accurate, and structural faults in the medium will be automatically compensated for.
