Definitions
- the projection area of the dielectric to the reflector is selected to be not larger than the area of the reflector.
- both of a length in the axial direction of the dielectric equivalent piece or the magnetic equivalent piece and a maximum length of a sectional external form in a virtual plane of an arbitrary position parallel to the reflector are selected to be the operating wavelength multiplied by 2.5 or less.
- the electromagnetic wave is reflected along the direction of arrow A1 as mentioned above, and by such electromagnetic wave, the gain is increased by the diffraction at the end parts 15, 16 of the reflector 13 and dielectric 14. That is, the electromagnetic field distribution (especially the phase) in the vicinity of the dielectric 14 may be made uniform. Making uniform here means the action of superposing the electromagnetic wave reflected or diffracted by said end parts 15, 16, and the electromagnetic wave reflected in multiplex between the dielectric 14 and the reflector 13.
- the area of the reflector 13 is finite, and thereby by repeating reflection or diffraction at the end parts 15, 16, the phases of the emitted electromagnetic waves are aligned. As a result, the gain is enhanced.
