Claim Text:
1. A printed wide band monopole antenna module, comprising: a substrate having a first surface; a ground terminal part formed on the first surface; and an antenna body disposed on the first surface opposite to the ground terminal part, wherein the antenna body further comprises: a first extending part having a first length; a second extending part having a second length, wherein a width of the second extending part is equal to a positive first width value plus a positive second width value; a third extending part having a width equal to the first width value so that the width of the third extending part is smaller than the width of the second extending part, wherein the second extending part forms a connection between the first extending part and the third extending part; and a feeding part whose one end is connected to a position between the first extending part and the second extending part and the other end is corresponding to the ground terminal part, wherein a width of the first extending part is equal to the width of the second extending part, wherein the ground terminal part comprises: wherein the first length of the first extending part is in part determinative of a working frequency of the antenna body, and the width of the second extending part is in part determinative of a frequency bandwidth of the antenna body, wherein the second interval, the third interval and the slot achieve impedance matching of the antenna body at two resonant frequencies of the antenna body between 1.7 and 2.7 GHz.
