Quintuple Microstrip Patch Antenna with e-Slot at Different Rotation Angles
In this paper, the authors present an effective designs procedure for a single and dual band microstrip antenna for S-band (2GHz, 2.29GHz, 2.31GHz, 2.36GHz, 2.37GHz, 2.38GHz, 2.60GHz, 2.63GHz and 2.67GHz) which are used in many applications. Quintuple patch antenna with Eeslot (ellipse arms) is presented in this paper. This slot is rotate in five cases with the following angles (45,135,180,225 and 315) degree and in each step of rotation, the antenna parameters are studied. The minimum value of return loss among the whole cases is 34.18dB, achieved at 2.38GHz, when the maximum gain is 15dB.
