Double Layers of Truncated Semi Rectangular Monopole Design with Trimmed Half Ground Plane

摘要

In this research, a new extreme compact half rectangular monopole antenna with modified ground plane is proposed. The antenna is composed of a semi rectangular radiator with modified partial ground plane. The ground plane contains I shapes slots providing ultra-wide operating frequency from 2.6 till 14 GHz based on - 10 dB standard. In addition, the proposed monopole is characterized by its extensively reduced structure. The patch is printed on a substrate material of Rogers Duriod RT5880, which has relative permittivity of is an element of r = 2.2, with a total size of 10 x 14 x 0.9 mm(3). The antenna has been studied, and optimized with respect to impedance matching, bandwidth, size, radiation characteristics, and fabrication cost. Both simulation results and experimental measurement are shown with good agreement. The proposed design results show that the monopole is suitable for ultra-wide band systems.
