Circular Patch Antenna

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.

Circular Patch Antenna

An antenna is a crucial component in the wireless communication system which converts electrical waves to EM waves and vice-versa which leads to revaluation in wireless communication technology. Due to this reason the experiment was performed on a simple circular patch antenna for better radiation along with wide transmission bandwidth. In this paper, a simple circular microstrip antenna structure is designed to operate at dual bands. The proposed antenna consists of a circular radiating patch, a 50-ohm feedline line, a quarter-wave impedance matching transmission line, and a ground plane. It meets significant requirements for large bandwidth, optimized gain, minimum reflections, and small size with high directivity and efficiency. This antenna contains FR4 Epoxy substrate material with permittivity 4.4 and size 36mm x 36mm x 1.67mm. ANSOFT HFSS simulator is used to analyze various parameters like return loss, VSWR, Impedance, and gain. The Resonant Frequency of the designed antenna is 8.77 GHz and 10.6 GHz. with minimum Return Loss of -52 dB and -21.66 dB respectively. It was also observed that 1.005 and 1.2 VSWR at 8.77 GHz and 10.6 GHz respectively.
