Ultra wide band miniaturized dipole antenna with improved gain and beam stability

Abstract

A dipole capable of radiating in a wide frequency range of 2.7-4.3 GHz has a folded dipole conductive pattern that is formed on the upper surface of a PCB and a passive conductive pattern that is formed on the lower surface of the PCB providing a wide-band nature to the antenna element. The folded dipole conductive pattern has four base regions, each having a bond pad and four meander traces that couple the adjacent base regions. Each of the four base regions electrically couples to its corresponding balun circuit at one of four solder joints at a corresponding solder joint tab, wherein each of the solder joint tabs mechanically couples with the PCB at one of its four corners. The dipole may also include a passive director that is disposed on an upper surface of the PCB in an open region defined by the folded dipole conductive pattern.
