Abstract:
1. A multiband antenna, comprising: a feeding member having a receiver and a first side, wherein the receiver is configured to receive a signal from a coaxial cable; a short-circuit member having a second side disposed across from the first side to form a specific gap, wherein the short-circuit member is not physically connected to the feeding member and an induced signal is generated on the short-circuit member to excite a high-frequency resonant mode from the feeding member due to capacitive coupling effect of the specific gap by means of capacitance between the short-circuit member and the feeding member; a radiation conductor, physically connected to one end of the short-circuit member, wherein the radiation conductor is adapted to excite a low-frequency resonant mode by the specific gap when the feeding member receives the signal; and a grounding plane physically connected to another end of the short-circuit member.
