Rectangular with half circle cut-out microstrip patch antenna for C-band applications

Aim: This study aimed to develop and analyse a bandwidth-enhanced C band antenna loaded with EBG and FSS Structures to improve the antenna performance. Methods: This paper illustrates the design of a semi-circular microstrip antenna with a modified circular ring Frequency Selective Surface (FSS) and an Electromagnetic Band Gap (EBG) structure for improved bandwidth and an omnidirectional pattern. The patch antenna is aimed at C-Band intersatellite communication links in a constellation. Results and Discussion: In literature, the application of EBG and FSS together is seldom used. The semicircular patch is aimed at retaining the omnidirectional antenna pattern at higher frequencies, as well as bandwidth, which is achieved through FSS and EBG structures. The modeling and simulation of the antenna have been carried out with 3D EM solvers. The simulated patch antenna operates in a wideband ranging from 4.1 GHz to 7.1 GHz with a gain of 1.9 dB at 5.33 GHz and 1.4 dB at 4.5 GHz. Conclusion: The proposed antenna design is vertically polarized. The simulation results are validated with measurement results.

This article presents a proposal about an octagonal microstrip patch antenna (MPA) loaded with Split Ring Resonators (SRR) the antenna’s ground part. The antenna size reduction using multiband radiators will suits for miniaturization of day-to-day handheld devices. The dual band behaviour of the antenna will integrate more communication standard in one system which saves the installation space in the device. In this context, an octagonal antenna structure is conceived for a dual operational frequency of 5.63 GHz and 5.97 GHz. Hereby, a Co-planar Waveguide (CPW) structure is adapted to the octagonal patch and the structure has been observed by simulation analysis under HFSS platform. The overall geometry of the antenna is 30 x 26 x 1.6 mm3. The antenna feed using a microstrip for earning a better impedance matching between the antenna and transmission line. The antenna design provides a wider bandwidth of 580MHz and average gain of 3.25 dBm. The attainment of dual band operational frequencies is due to the CPW and SRR structure in the antenna design.
