A circularly polarized printed linear antenna array, fabricated in low cost FR4 substrate and suitable for L‐band satellite data terminals is presented. The main contributions of the article are twofold. First, a three times bandwidth increase compared to a single notched disc element is demonstrated through the utilization of aperture feeding and sequential rotation. Second, array configurations with small separations that can arise in situations with space constraints are investigated. Elements with modified dimensions were found to be a simple and efficient remedy that mitigates the effect of mutual coupling. The suitability of the array for its use in L‐band satellite data terminals with reduced pointing requirements is also discussed. © 2013 Wiley Periodicals, Inc.
