Abstract

Disclosed is a MIMO antenna for improved isolation. The disclosed antenna comprises: a first conductive member electrically connected to a feed point; a second conductive member separated a predetermined distance from the first conductive member and electrically connected to a ground; at least one spiral cell coupled to the first conductive member and the second conductive member between the first conductive member and the second conductive member, and including at least two spiral arms; and an emitter extending from the second conductive member. According to the disclosed antenna, isolation characteristics between multiple antennas can be improved, and good isolation characteristics can be obtained even when the distances between multiple antennas are relatively short.

Description

technical field [0001] The present invention relates to a built-in antenna, in particular to a built-in antenna for preventing interference between antennas and improving isolation characteristics. Background technique [0002] With increasing requirements for multimedia services, mobile communication systems are required to be able to transmit reliable and high-speed data. To transmit high-speed data through wireless waves using limited frequency bands and power must increase its capacity. At present, technologies capable of improving capacity are attracting attention. [0003] The wireless communication environment is affected by fading, yin and yang effects, propagation attenuation, and reflections, and the reliability of received signals is greatly reduced. Therefore, in order to realize high-speed data transmission, it is necessary to overcome the defects of wireless channel characteristics or utilize its properties. Multiple input multiple output (multiple input mul...
