Latest Patents
One of Keith M Keen's latest patents is the "Folded Dipole Microstrip Antenna." This invention includes a dielectric substrate that defines two mounting surfaces, with a folded dipole radiative element mounted on the second surface. The microstrip antenna features a feed line on the first surface, which excites the radiative element in response to an excitation signal. A preferred implementation involves applying the excitation signal through a coaxial cable. The design includes a continuous dipole arm arranged parallel to two dipole arm segments, separated by an excitation gap. The feed element aligns with the excitation gap and connects electrically to the continuous dipole arm. Additionally, the antenna may have a ground plane reflector separated by a dielectric spacer, which projects electromagnetic energy in a predetermined direction. The thickness of the dielectric spacer is carefully selected to ensure that the antenna presents an impedance of approximately fifty ohms to the coaxial cable.
