ABSTRACT:
A compact broadband log-periodic antenna for transmitting and receiving frequencies between 0.5 to 18 GHZ. The antenna comprises two dielectric substrates bonded together, both substrates comprise a first group of dipole elements configured in a log-periodic sequence and a second group of serpentine configured dipole elements fabricated on the same substrate and in electrical communication with the first group of elements. The serpentine dipole elements are configured in a specific pattern such that the size of the antenna is reduced, yet still maintains log-periodic characteristics. Disposed between the two substrates is a feed system in electrical communication with both groups of elements such that a connector from a transmitter or receiver can be in communication with the antenna.
