Abstract

This paper describes the concept, design, and measurement of a multi-band circularly polarized printed slot antenna with a single microstrip feed line. The antenna design for circular polarization (CP) at 1.5 GHz for GPS, 2.4 GHz for Bluetooth, and 3.75 GHz for WiMAX application is given. The proposed antenna also provides a fourth linear polarized band over 5.2 to 6 GHz covering the WLAN band. The design is such that all three CP bands can be tuned for any other desired frequencies. Three configurations of the proposed antenna with different design parameters for different circularly polarized bands are reported in the paper. A prototype of the proposed antenna is fabricated, and measured results are compared with those of the simulations.
