Patent ID: 7324059

Claim:
A stub printed dipole antenna comprising: a substrate having a relative permittivity; dipole arms disposed at both surfaces of the substrate for transmitting/receiving a signal, wherein each dipole arm has a length of A and a width of W A ; parallel metal strip lines disposed at both surfaces of the substrate, and each having one end connected to each of the dipole arms, wherein each metal strip line, has a length of (F-R) and a width of W F ; a stub disposed at both surfaces of the substrate, and connected to the other end of the parallel metal strip lines wherein the stub has the width of the strip lines being W F and a length R extending in the linear direction of the parallel metal strip lines; a coaxial probe connected to the junction of the parallel metal strip lines and the stub for feeding signals; a hole for inserting an inner conductor of the coaxial probe; and a contact for connecting to an outer conductor of the coaxial probe.
