Multi-band microstrip meander-line antenna

A multi-band microstrip meander-line antenna comprising:

• a substrate;
• a first meander-shaped conductor disposed on the substrate in a first reciprocating bend manner for providing a resonant frequency band corresponding to a first frequency;
• a second meander-shaped conductor disposed on the substrate in a second reciprocating bend manner for providing a resonant frequency band corresponding to a second frequency, wherein the first or the second meander-shaped conductor consists of a plurality of first sections disposed along a direction parallel to signal polarization and a plurality of second sections disposed along a direction perpendicular to signal polarization, and each first section is wider than each second section;
• a first feed line having a first end electrically connected to a first feed point of the antenna and a second end electrically connected to an end of the first meander-shaped conductor;
• and
• a second feed line having a first end electrically connected to a second feed point of the antenna and a second end electrically connected to an end of the second meander-shaped conductor.
