Title: Wide-band micropstrip dipole antenna array
Inventor: FIMOFEEV IGOR E
IPC: H01Q1/52
Filed: 1999-06-09
Abstract: A microstrip dipole antenna array includes N equally spaced PCBs 22 parallel. Each PCB 22 includes at least one microstrip dipole 24 and microstrip feed 26. The PCBs 22 are symmetrically located between (N+1)  metal plates 32. The metal plates 32 act as a back reflector for the antenna array in substitution for a perpendicular ground plate (18, fig 1). The use of such metal plates 32 gives the antenna a lower wind-load area, than it would have if a ground plate(18, fig 1) was used. The use of such plates 32 reduces the coupling between dipoles in the H-plane whilst increasing the antenna's band width and allowing the free flow of air if device needs to be cooled. In an alternative embodiment the antenna array further comprises slender wires (36, fig 3 ), which are located between the PCBs 22 and the plates 32 so as to improve the front-to-back radiation ratio of the antenna.
