Title:
LOOP ANTENNA
Document Type and Number:
WIPO Patent Application WO/2014/126040
Kind Code:
A2
Abstract:
A loop antenna (10) comprises an antenna element (12) configured by forming a uniplanar loop from a conductive line on the surface of a dielectric substrate, the contours of the loop including protruding sections (14a, 14b, 14c, 14d) protruding in four directions in the shape of a cross. A power supply unit (17) for connecting the power supply line is provided at one location on an internal corner formed by the conductive line in the antenna element (12). Thus, it is possible to significantly decrease the size of the loop antenna in comparison to conventional antennas without compromising antenna characteristics such as the impedance and emission characteristics.
