Compact LTCC Dual-Band Circularly Polarized Perturbed Hexagonal Microstrip Antenna

A novel dual-band circularly polarized multilayer microstrip antenna for 3.5/5.2-GHz applications is presented. A stacked-patch configuration is used for the compact dual-band antenna design, and good circular polarization (CP) performance is achieved by adjusting the size of truncated corners and inserted slits of the hexagonal patches. The antenna generates CP radiation at 3.5 and 5.18 GHz with broadside radiation patterns and very low axial ratio. The measured peak gains of the antenna are 3.8 and 5.4 dBi at the lower and upper bands, respectively. The antenna occupies a small radiating area of 19.2 × 16.6 mm2.
