WIDE-BAND ANTENNA |
摘要 |
A monoconical antenna comprises a generally conical hollow formed in one end of a dielectric body, a radiation electrode formed on the surface of the hollow, and a ground conductor formed closely and generally parallel to the other opposing end of the dielectric body. An electrical signal is applied between a near-vertex portion of the radiation electrode and a portion of the ground conductor. The half-cone angle (alpha) of the generally conical hollow is determined according to a certain rule which corresponds to the relative dielectric constant (ϵr). With this constitution, the monoconical antenna is miniaturized through dielectric loading while sufficiently maintaining its intrinsic wide-band characteristics.
