Abstract :
Novel designs of single-feed circularly polarized microstrip antennas using slotted equilateral-triangular patches have been successfully demonstrated. Both cases of regular-size and compact circular polarization (CP) operations using the designs with, respectively, a narrow horizontal slot and a cross slot of unequal slot lengths embedded in the triangular patch are experimentally investigated. For the compact CP design, an antenna size reduction of about 17% as compared to the regular-size CP design is also obtained.
