MULTI-BAND MONOPOLE PLANAR ANTENNAS CONFIGURED TO FACILITATE IMPROVED RADIO FREQUENCY (RF) ISOLATION IN MULTIPLE-INPUT MULTIPLE-OUTPUT (MIMO) ANTENNA ARRANGEMENT

摘要

Embodiments disclosed include multi-band monopole planar antennas configured to facilitate radio frequency (RF) isolation in multiple-input multiple-output (MIMO) antenna arrangement, in one aspect, a multi-band monopole planar antenna is provided and configured to generate a slant 45° radiation -polarization in the lower frequency band. As a result, sufficient RF isolation may be achieved in the lower frequency band when a plurality of dual-band monopole planar antennas is placed in the MIMO arrangement. In another aspect, the multi-hand monopole planar antenna is configured not to support certain unused RF bands, thus facilitating height reduction in the multi-band monopole planar antenna. By configuring the dual-band monopole planar antemia to generate the slant-45 radiation polarization in the lower frequency band, a plurality of the multi-band monopole planar antennas may be placed in close proximity to each other to support MIMO operation without compromising RF performance.
