Title:
SMALL-SIZED DUPLEX C PATCH TYPE ANTENNA THAT IS INCORPORATEDINTO STANDARD PC CARD
Document Type and Number:
Japanese Patent JPH08298411
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent any influence even when this device is present near a human body, and to cancel the generation of a problem in multiple reflection and the rotation of a polarization plane in a microstrip antenna structure. SOLUTION: A module 1' inserted into a data processor 2 includes an interface, MODEM, RF energy transmitter, RF energy receiver, and partially short- circuited double C patch type antenna. This antenna is composed of a truncated ground plane 22, layer 28 of dielectric materials having a first face on the ground plane and a second face on the opposite side, and electric conductive layer 30 on the second face on the opposite side of the dielectric layer. The electric conductive layer is provided with a rectangular aperture having length extended along the first edge of the electric conductive layer and width extended toward the second edge positioned on the opposite side on which a radiation patch is formed.
