Wide band antenna

A wide band antenna, comprising:

• a first patch having a first portion and a second portion connected to said first portion, said first portion and said second portion respectively defining opposite sides;
• a second patch having a third portion and a fourth portion connected to said third portion, said third portion and said fourth portion respectively defining opposite sides;
• a ground patch arranged close to said first portion of said first patch and said third portion of said second patch;
• and
• a feeding point arranged at said first portion of said first patch, wherein one side of said first portion of said first patch faces one side of said third portion of said second patch to form a gap therebetween, and one side of said second portion of said first patch faces one side of said fourth portion of said second patch to form a gap there between;
• wherein said wide band antenna is mounted to a dielectric element having a top surface, a bottom surface opposite to said top surface, a front surface connected to said top surface and said bottom surface, opposite side surfaces connected to said top surface, said bottom surface and said front surface, said first patch and said second patch mounted to said top surface and said front surface, said ground patch mounted to said bottom surface and said front surface;
• wherein said dielectric element has a fixing plate projected from said side surfaces and at least a fixing bore opened on said fixing plate;
• and
• wherein said ground patch has at least an elastic contact, said elastic contact projected from portion of said ground patch which is mounted to said bottom surface of said dielectric element.
