The sequential rotation technique is used far the design of circularly pola
rized (CP) dielectric resonator antenna (DRA) subarrays. Two configurations
are considered. The first one employs linearly polar; ized (LP) DRA elemen
ts whereas the other one uses CP DRA elements. The characteristics of the T
wo configurations are compared and discussed. In the CP-element case, the p
erformance of the the subarray is also compared with that of the single-ele
ment configuration. (C) 2000 John Wiley & Sons, Inc.
