Abstract :
Typical crosspolar levels of ¿33 dB in the reflection band and slightly lower levels in transmission were recorded for the concentric ring array in the 45° planes of the feed/array combination. The Jerusalem cross array gave higher levels in transmission. The band centre frequency ratios were 1.4 and 1.6.
