OMNIDIRECTIONAL RADIATION BROADBAND ANTENNA FOR COVERING ENTIRE UHF BAND

摘要

PURPOSE: An omnidirectional radiation broadband antenna is provided to obtain a correct matching level over the entire band by covering the entire band between 470MHz to 862MHz. CONSTITUTION: An omnidirectional radiation broadband antenna includes a first circular monopole(3) or a first semicircular monopole perpendicular to an earth plane(1). The omnidirectional radiation broadband antenna further includes at least a second circular monopole(4) or a second semicircular monopole. The first and second monopoles are positioned at a predetermined position having a common diameter(z). The omnidirectional radiation broadband antenna includes N circular monopoles(N>=2). The N monopoles are positioned at the predetermined position to exhibit the common diameter.
