Abstract (2. Language): 
In this paper, a single balanced feeding circularly polarized planar microstrip antenna array working at 2.2 GHz is designed. Gain, VSWR and axial ratio parameters are compared by taking 0.54l0 and 0.8l0 as the distances between two elements. As result of Laboratory measurements and simulations using the full moment method, half power beam widths of approximately 24o and 22o are obtained. By calculating the radiation losses of both arrays individually, the gains of the arrays are calculated. Bandwidths of approximately 30 and 40 MHz are obtained around the resonant frequencies 2.198 GHz and 2.22 GHz respectively.
Abstract (Original Language): 
Bu makalede tek dengeli ortadan beslemeli dairesel kutuplanmış 2.2 GHz de çalışan düzlemsel bir dizi anten tasarlanmıştır. Elemanlar arasındaki boşluk 0.54l0 ve 0.8l0 alınarak kazanç, VSWR ve eksenel oran parametreleri karşılaştırılmıştır. Laboratuar ölçümleri ve full moment metodu kullanılarak yapılan benzetim sonuçlarında 24o ve 22o dar , yarım güç ışın demeti genişlikleri elde edilmiştir. Her iki düzlemsel anten dizisinin de ışıma kayıpları hesaplanarak kazançları bulunmuştur. Antenlerin rezonansa geldikleri 2.198 GHz ve 2.22 GHz civarında yaklaşık 30 ve 40 MHz’lik bant genişlikleri elde edilmiştir.
