WebMar 31, 2024 · A dipole antenna is an antenna with two radiators: The length of each radiator is related to the wavelength of the frequency that must be received or transmitted. Embedded chip antennas have only one radiator. So, for the antenna to function, the ground plane of the host PCB becomes the second radiator. WebThe 1/2 wave antenna is a center fed dipole (it can be fed off-center with the same result), and the 1/4 wave ground plane uses 4 sloping radials. With that caveat, let’s see how they compare: Comparative patterns of 1/2 wave dipole, 5/8 wave over horizontal radials, and 1/4 wave ground plane over sloping radials.
