antenna is presented. This antenna offers considerable area re- TABLE 2. Variation of Resonant Frequencies
duction compared to standard rectangular microstrip antenna designed
for the same frequency. Typical antenna design and
experimental results for circular polarization are also demonstrated.

Abstract:
A new compact dual-band, dual-polarized microstrip antenna
is presented. 7'iris antenna resonates at two frequencies with
different polarizations: a linearly polarized one for terrestrial
communication, and a circularly polarized one for satellite mobile
communication. This antenna also provides an area reduction of 70%
compared to a standard rectangular patch antenna

Abstract:
Dual frequency operation is achieved from a compact
microstrip antenna by loading a pair of narrow slots close to its radiating
edges. The two frequencies have parallel polarization planes and similar
radiation characteristics. The ratio between the two operating frequencies
can be tuned in the range (1.14-1. 24), which is much smaller than that
of similar designs. The above excellent radiation characteristics are
achieved along with an area reduction of - 75% compared to the
standard rectangular patch
