Abstract
A dipole antenna includes a circuit board with a first side and a second side, at least one dipole disposed on the circuit board comprising an upper half and a lower half, a microstrip transmission line disposed on the circuit board coupled to at least one of the upper half and lower half of the at least one dipole, and a choke element disposed on the circuit board. The choke element and the lower half of the at least one dipole form an open slot trap with a high impedance point.

A choke disposed on a circuit board having a dipole of a dipole antenna, the choke comprising:
- a center trace element having a first length;
- and
- first and second sleeve elements disposed along and on either side of the center trace element;
- wherein the center trace element is in physical contact with a lower half of the dipole of the dipole antenna and the first and second sleeve elements are physically isolated from the lower half of the dipole of the dipole antenna.
