Design of Circular Patch Antenna with Coplanar Waveguide Feed for LTE Application

Abstract

In this paper, a circular patch antenna with Coplanar Waveguide (CPW) feed for LTE application is proposed. The proposed antenna design exhibits a decent impedance matching inside the LTE Bands 2.6 GHz. The planar monopole antenna with coplanar waveguide (CPW) feed has been considered here. It has greater advantage over microstrip compose feed lines, low scattering, low radiation spillage, the capacity to successfully control the trademark impedance, and the simplicity of mix. Rogers RT/duroid 5880 is used as substrate having a dielectric constant of 2.2 with a thickness of 1.6 mm and the conducting surface as copper. The proposed antenna obtains a narrow bandwidth in the frequency range of 2.6 GHz. It is suitable for LTE application because of its compact size and less cost to fabrication. The gain and efficiency of this antenna is good. The antenna is designed with the help of High Frequency Structure Simulator (HFSS) software.
