DUAL BAND LOW-PROFILE ANTENNA APPARATUS OF M TYPE STRUCTURE AND THE PRODUCT METHOD THEREOF

摘要

The present invention relates to a dual-band low profile antenna mountable in a mobile transceiver for Terry methoxy tree communication, the device ground plane, it is fastened to the ground plane of the power feeding connector, a source of the connectors for applying a source (Source) the feed pin, shorting the M-shaped radiating element and the ground plane and the M-shaped radiator for radiating a radio wave through the power supply pins and and so configured to include a dielectric to be structurally robust, but also, a manufacturing method constituting a ground plane step, the step of is fastened to the ground plate configuring the connector to be applied to the source (source) to the power supply pin, the method comprising: configuring the power supply pin to the power supply source of the connector, an antenna for radiating a radio wave through the feed pin length to extend the step of configuring the radiating element to the M-shape and the ground plane and the M-shape defined only by electrical coupling with the radiating element A and it comprises the steps of: to form a further capacitance (C) to the variable capacitance to form the conductor.; Therefore, according to the present invention to form a capacitance (C) via an electrical coupling (Coupling) of the M-shape by using a radiator antenna ground plane and the M-shaped emitters of the vehicle to an antenna using a capacitive passive element of variable capacitance conductor at the same time and it can implement downsizing and low profile antenna to the air friction to a minimum, which is possible to provide a dual band antenna for generating a double resonance in the UHF band and the L band.
