Itasca, IL, May 14, 2019 --(PR.com)-- The redesigned Y42700WB Log Periodic Antenna from Mobile Mark Antenna Solutions, now provides wideband coverage from 600-6000 MHz.
Various types of antennas offering wide bandwidth and high gain have been discussed in literature, including the dielectric rod antenna, spiral antenna, horn antenna, and log periodic antenna [22-25].
Wideband operation is achieved when all the switches are in the OFF state thus making the antenna act as a normal log periodic antenna. To demonstrate narrow band operation, such as in a high band mode, four of the highest frequency slots were kept open.
The source is a linearly polarized, log periodic antenna that operates from 500 MHz to 12.4 GHz.
