Design and Simulation of Linear Series-fed Low-sidelobe Microstrip Antenna Array

In this paper we introduce a new antenna array with high sidelobe suppression. Antenna consists of six microstrip patches. Antenna is designed and realized in the frequency range about 5.785 GHz which is popular for microwave communication networks. Sidelobe suppression is better than 16 dB in E-plane. Bandwidth of the antenna is wider than 6.5%. Antenna is suitable for integration with other microwave circuits. Agreement between simulation and measured results is good. The array is series-fed so it is very easy to fabricate and quite low cost.
