Compact dual frequency dual polarized cross patch antenna with an X-slot

A new design of a compact single-feed dual frequency dual polarized microstrip antenna with an X-slot is presented. The proposed antenna generates two orthogonally polarized radiations with center frequencies at 1.42 GHz and 1.79 GHz, respectively. For fixed dual frequency operation, the antenna has an area reduction of 74% and 59% for the respective frequencies compared to standard rectangular patches. The antenna exhibits broadside radiation pattern and has sufficient gain for the two bands. © 2008 Wiley Periodicals, Inc.
