A Superior Lower-Cost Dual-Polarized MPAR Array Antenna

FreEnt proposes a next generation low cost, dual-polarization Ultra-Wide Band (UWB) Connected Array antenna for MPAR. The new array supports both weather surveillance and surveillance with pristine cross polarization performance. Key attributes are low cost COTS, complete frequency and waveform flexibility, and pristine polarization performance and isolation with the following benefits: • Pristine Polarization Diversity – Designed with both H and V polarizations. Laboratory measurements indicate current crosspol port isolation better than -35 dB. • Low Cost – The design eliminates supporting components such as impedance transformers, baluns, circulators, etc., and reduces the number of phase shifters significantly. This will result in reduced size and cost savings. • Unlimited Bandwidth Without Dispersion – Our array is limited only b physical size of the array for low frequency cutoff and by the clo9sest manufactured element spacing for high frequency cutoff. Thus any in-band frequency and waveform is supported.
