<p>Disclosed is a dual-band monopole antenna with antenna signal fed through a short-circuit terminal (222, 33, 422, 521) of a transmission line load (2, 3, 4, 5). The dual-band monopole antenna includes an antenna extension section (1, 1a) and a transmission line load (2, 3, 4, 5). The antenna extension section (1, 1a) has a top terminal (11) and a transmission line connection terminal (12). The transmission line connection terminal (12) is connected to the transmission line load (2, 3, 4, 5). The transmission line load (2, 3, 4, 5) includes a core transmission line (21, 31, 41, 51), an outer circumferential conductor (22, 341, 342, 42, 52), and a dielectric layer (23, 43, 53). The core transmission line (21, 31, 41, 51) has an extension section connection terminal (211, 311, 411, 511) and a signal feeding terminal (212, 312, 412, 512). The extension section connection terminal (211, 311, 411, 511) is connected to the transmission line connection terminal (12) of the antenna extension section (1). The outer circumferential conductor (22, 341, 342, 42, 52) circumferentially surrounds and is spaced from the core transmission line (21, 31, 41, 51) by a given distance and the outer circumferential conductor (22, 341, 342, 42, 52) has an open terminal (221, 321, 421) and a short-circuit terminal (222, 33, 422, 521).</p> |
