BROADBAND PRINT-TYPE DIPOLE ANTENNA

摘要

PURPOSE: A broadband print-type dipole antenna is provided to be capable of transmitting and receiving an electro magnetic signal over a broadband by providing a broadband design guide of a dipole antenna. CONSTITUTION: A broadband print-type dipole antenna has a power feeder, is placed on a dielectric substrate, and transmits and receives an electro magnetic signal over a broadband. A ratio of a length(L) to a width(W) of each arm of a print-type dipole(100) is equal to or more than 0.9 or equal to or less than 1.1. A gap(G) between dipole arms is 0.1L. The print-type dipole is disposed on one surface of the dielectric substrate(110). A reflection part(310) is spaced apart from the dielectric substrate and is connected to a ground to form a radiation pattern of one direction. Baluns(320,330) are disposed between the dipole and the reflection part and feeds a current to the dipole.
