In this article microstrip planar array of eight elements is designed and simulated. It operates in the frequency range from 3.7 to 4.2 GHz. It gives gain of 17 dB. It can produce many types of polarizations such as Eθ, EΦ, right, and left circular. In all these polarizations the cross‐polar level is around 20 dB lower than the copolar level (except for Eθ, for Eθ it is around 10 dB). The novel microstrip antenna element used in this article is constructed using parasitic patch and shorting pins. It gives wide bandwidth and various polarizations due to parasitic patch and shorting pins, respectively. The array is simulated using Agilent's ADS 2003A momentum software. © 2007 Wiley Periodicals, Inc.
