MONOPOLE ANTENNA HAVING RADIATOR OF ELLIPTIC CYLINDER SHAPE

摘要

PURPOSE: A monopole antenna is provided to be capable of being used over a broadband and a low frequency band. CONSTITUTION: The first radiation pole(1) is projected from a ground plane(2) and has a predetermined height. The first radiation plate(3) is loaded on an end of the first radiation pole, and the first radiation cylinder(4) is formed along an edge of the first radiation plate. The second radiation pole(9) is connected to the first radiation pole and is projected on the first radiation plate. The second radiation plate(10) is loaded on an end of the second pole, and the second radiation cylinder(11) is formed along an edge of the second radiation plate.
