EMC Test Log Periodic Antennas

The TDK PLP-3003 Precision Log Periodic Antenna is a new generation compact antenna designed for metrology applications. The PLP-3003 provides optimal performance over the wide operating frequency range of 300 MHz to 3 GHz, and features moderate power handling capability.

Leading-Edge Design
The PLP-3003 features excellent cross polarization rejection, improved pattern symmetry, and a low VSWR.

The TDK LPDA-8003 Log Periodic Dipole Antenna is a new generation compact antenna used for transmitting and receiving broadband radio signals. It is especially suited for dual band communication testing where the antenna must not interfere with the measurement environment. The LPDA-8003 provides optimal performance over the wide operating frequency range of 800 MHz to 3 GHz. The LPDA-8003 features reduced cross polarization, improved pattern symmetry, and moderate power handling capability, making it an excellent choice for both communications testing as well as the most stringent metrology applications.

Leading-Edge Design
The LPDA-8003's compact design features a reduced boom size which results in excellent cross polarization rejection. The antenna's patent-pending balun design provides improved pattern symmetry and a low VSWR.

The TDK LPDA-0801 is a medium gain Log Periodic Dipole Array that provides strong performance over the operating frequency range of 80 MHz to 1 GHz. The LPDA-0801 features very high power handing (2.5 kW continuous) capabilities to accommodate the most extreme EMC test requirements.

Patent-Pending Design
The LPDA-0801 features a patent-pending boom/feedline design that greatly enhances the antenna's performance over traditional LPDA models while maintaining a compact form factor. This unique design facilitates heat transfer, which yields very high power handling with extremely low loss and greatly improved efficiency.

Dual Use
The LPDA-0801 is designed for immunity measurements, but the reduced-sized precision feedline cross section translates into low cross-polarization and excellent pattern symmetry, making the LPDA-0801 an excellent emissions measurements as well.

Robust Construction
The LPDA-0801 is precision built to very tight tolerances and features an ultra-robust mechanical design, resilient gold chromate finish, and a highly durable feed to withstand the rigors of daily use in EMC test environments. The antenna can be mounted on a conventional antenna tower or on one of TDK's line of antenna masts.
