Abstract

A novel dual side‐feed circularly polarized ceramic chip antenna suitable for surface mounting on a system circuit board is presented. The antenna mainly comprises a square radiating patch, a square ground plane, and two vertical conformal strips for the dual side‐feed, which are printed on the top, bottom and side surfaces of a ceramic chip. For obtaining circular polarization (CP) radiation for global positioning system (GPS) operation at 1575 MHz, a prototype using a square‐disk ceramic chip of dimensions 4 × 17.5 × 17.5 mm^3^ and relative permittivity 45 was studied, and the experimental results are presented. © 2002 Wiley Periodicals, Inc.
