Abstract In this work, a circular patch antenna is designed and a parametric study in terms of different geometrical parameters is conducted. As a second step, a parasitic chip is introduced on top of the proposed circular patch antenna in the aim to enhance the gain and antenna efficiency. The proposed antenna operates at 25.61 GHz (With a frequency range between24.383 GHz and 27.7 GHz), suitable for 5G applications. The antenna modelling with and without parasitic chip, along with the performance analysis is conducted with CST Studio Electromagnetic (EM) simulator software. A compact size of 10×10×1.547 mm3, easy to fabricate, broadband characteristics up to 3.31 GHz with a high gain up to 6.87 dB, total efficiency of 95 % and a minimum return loss low than -68.02 dB covering the operating frequency range. Lastly, to investigate and validate the antenna overall performance, both frequency and time domain-based simulation is performed, and a good agreement is obtained.

In this paper, Ultra wideband planar circular patch and half circular ring patch antennas are proposed. These newly simulated structures are proposed for fabrication. The antennas are suitable for operating frequency of 7.5 GHz. It is shown that return loss of the both the antennas at 7.5 GHz is better than -10 dB. The VSWR obtained is less than 2. The half ring patch antenna is found to have the compact size and more bandwidth as that of circular patch antenna. HFSS11 is used for the simulation. From HFSS11 simulations, dimensions of antennas are chosen for better performance. Details of the proposed antenna design and measured results are presented in this paper

This proposes a new diminutive octa polarization reconfigurable circular patch antenna design. This new antenna can operate in eight different polarizing states (6 different angles of linear polarization and 2 circular polarization states) with the help of a reconfigurable probe feed network. The antenna comprises of a circular layer of radiation with four equally spaced slits at the boundary of the circular patch to obtain size reduction. The bias voltages of six pairs of PIN diodes are interval between each state. A 3 dB hybrid coupler and a RF switch are used to produce reconfiguration between circular polarization states of the right and left hand. The proposed antenna was designed using CST microwave studio, fabricated as a prototype model and tested which produces desired values for various parameters of antenna including compact size. The designed antenna operates within 2.4-2.5 GHz frequencies suitable for wireless applications

In this paper, a compact frequency reconfigurable circular patch antenna with an arc-shaped slot loaded in the ground layer is proposed for multiband wireless communication applications. By controlling the ON/OFF states of the five PIN diodes mounted on the arc-shaped slot, the effective length of the arc-shaped slot and the effective length of antennas current are changed, and accordingly six-frequency band reconfiguration can be achieved. The simulated and measured results show that the antenna can operate from 1.82 GHz to 2.46 GHz, which is located in DCS1800 (1.71–1.88 GHz), UMTS (2.11–2.20 GHz), WiBro (2.3–2.4 GHz), and Bluetooth (2.4–2.48 GHz) frequency bands and so forth. Compared to the common rectangular slot circular patch antenna, the proposed arc-shaped slot circular patch antenna not only has a better rotational symmetry with the circular patch and substrate but also has more compact size. For the given operating frequency at 1.82 GHz, over 55% area reduction is achieved in this design with respect to the common design with rectangular slot. Since the promising frequency reconfiguration, this antenna may have potential applications in modern multiband and multifunctional mobile communication systems.
