Design of Double Layers Miniaturized Trimmed Semi-Rectangular Monopole with Partial Ground Plane for Short Ranges Wireless Systems

摘要

This paper presents a new miniaturized design of antenna with extremely wide bandwidth. The design consists of trimmed half rectangular patch printed on a 10x13 mm(2) substrate of Rogers Duroid RT5880Lz with relative permittivity of epsilon r=1.96 and loss tangent of 0.0009. The monopole has a partial modified ground plane structure to enhance the impedance matching and to provide wider bandwidth from 2.6 GHz to 15.7 GHz with reflection coefficient less than -10 dB. The proposed design has been tested, optimized, and experimentally measured for verifications; simulated and measured results have achieved high concord. The presented monopole is suitable for short range wireless systems as well as lower 5G bands applications.
