FERRITE MICROSTRIP ANTENNA CAPABLE OF MINIATURIZING A SIZE OF AN ANTENNA BY USING AN ANTENNA MATERIAL HAVING HIGH DIELECTRIC CONSTANT

摘要

PURPOSE: A ferrite microstrip antenna is provided to be built in a portable terminal by using a ferrite of high dielectric constant as dielectric.;CONSTITUTION: A ferrite microstrip antenna includes a feeder(100), a first substrate(200), a radiator, and a second substrate(210). A feeding signal is delivered to the feeder. A first via(201) is formed on the first substrate in order to extend the feeder. A patch ground(400) of metal material is formed on a bottom surface of the first substrate. The radiator is branched from the feeder extended on a top surface of the first substrate through the first via. The radiator is formed on the first substrate. The second substrate is formed on the first substrate. The first substrate and the second substrate are made of ferrite having magnetic permeability and dielectric constant more than 1.;COPYRIGHT KIPO 2010
