Abstract
The invention provides an antenna in which a signal is directly transferred from a planar dielectric transmission line to a primary radiator without having to perform transmission mode conversion from the planar dielectric transmission mode to another mode such as a coplanar transmission mode, a microstrip transmission mode, or a waveguide transmission mode thereby eliminating the transmission loss which would otherwise occur due to the transmission mode conversion. A dielectric resonator is disposed in the vicinity of the end of the planar dielectric transmission line PDTL formed between two slots disposed on both sides of a dielectric plate. Furthermore, a slotted plate, a lens supporting base, and a dielectric lens are disposed one on another.
