Abstract :
An ultra wideband cylindrical array consisting of 48 radial columns of end-fired elements is described. A 5-column mini-sector test array was built and tested. Test results for 100 to 900 MHz were recorded. Interleaved with the cylindrical array at the outer rim is a 96-element wideband (500-2000 MHz) ring array for IFF operation.
