Antenna with Anti-Interference Arrangement and Its Manufacturing Method

An antenna, comprising:

• an antenna body which comprises a radiating source comprises a radiating connection point being grounded and a feed point;
• and
• an oscillation circuit module which comprises a triode circuit processor having a first connection terminal electrically connected to a power source, a second connection terminal being grounded, and a third connection terminal electrically connected to said feed point of said radiating source, wherein said third connection terminal as an output end provides an excitation current to said feed point of said radiating source, such that said antenna body is excited to generate an electromagnetic wave signal.

A method of manufacturing an antenna which comprises at least a radiating source and a reference ground, comprising the steps of:

• (a) spacedly disposing said radiating source at said reference ground to define a radiation clearance between said radiating source and said reference ground;
• and
• (b) electrically connecting said radiating source to said reference ground to form an antenna body, wherein said radiating source is grounded to narrow a bandwidth of said antenna.

A method of enhancing an anti-interference ability of an antenna which comprises at least a radiating source and a reference ground, comprising the steps of:

• (a) forming a radiating clearance between said radiating source and said reference ground;
• and
• (b) grounding said radiating source by electrically connecting said radiating source to said reference ground to reduce an internal impedance of said antenna, such that when an excitation current is received at a feed point of said radiating source, a bandwidth of said antenna is narrowed down to prevent any interference of said electromagnetic wave signal received or generated by said antenna in response to nearby electromagnetic radiation frequency or stray radiation frequency of the adjacent frequency bands.
