In the wireless communication applications, widespread usage of microstrip patch antennas due to their advantages such as compactness, easy fabrication and low cost, is pushed forward researchers to develop desired antennas or improve the existing antennas to get desired one. But it is challenging to get desired antennas since microstrip patch antennas have some disadvantages such as low gain and narrow bandwidth. In this work, elliptical patch microstrip antenna is designed for Bluetooth/Wi-Fi applications. The antenna is designed in the form of slotted elliptical patch and defected ground structure method. Defected ground structure method is applied by using rectangular slots with different dimensions in this work. The proposed antenna is modelled using CST MWS software. Return loss, gain and directivity values are -16.45 dB, 1.82 dBi, and 5.81 dBi at 2.45 GHz, respectively. On the other hand, maximum directivity and gain values are 5.86 dBi and 2.06 dBi at 2.4 GHz, respectively. The bandwidth is 63.1 MHz (2.41 GHz – 2.48 GHz) at 2.45 GHz. According to the results, IEEE 802.11 b/g standards are supported by the designed antenna. So, it can be used for Bluetooth and Wi-Fi applications at 2.4 GHz.

Characteristic mode analysis (CMA) can be used in antenna designs to solve radiation problems. This review focuses on the existing development methodologies for circularly polarized (CP) antennas and their axial ratio bandwidth (ARBW) improvement using CMA. To discuss the physical insights related to CP radiation, this study systematically examines different antenna design structures used in previous research. It investigates the impact of modal parameters such as the eigenvalue, modal significance (MS), characteristic angle (CA), surface current, far-field radiation behavior on CP radiation, and ARBW for various antenna designs. In addition, it discusses the comparative analysis of various antenna design approaches in terms of antenna performance parameters such as the operating frequency band, ARBW, and gain. The results show that CMA provides more valuable information for the selection of feed position in antenna designs than the conventional full-wave simulation approach.

“…On the other hand, S11, gain and bandwidth parameters for 5.8 GHz can be given as -15.16, 3.9 dBi and 200 MHz (5.7 GHz -5.9 GHz), respectively. VSWR values are less than 1.5 for both frequencies (Uqaili, et al, 2020). A square patch microstrip antenna with asymmetric slit method that works at 2.4 GHz and 5 GHz frequencies is proposed by P. K. Goran and E. S. Nugraha.…”

In recent years, according to the requirements of wireless applications, multiband and low profile patch antennas are desired. In this study, a simple rectangular patch triband microstrip antenna is developed to use for Bluetooth/WiFi applications. The antenna is in the form of rectangular slots with different lengths loaded on the rectangular patch with reduced ground size. FR-4 substrate with 1.6 mm thickness is used as substrate material and annealed copper is used as ground and patch materials. The designed antenna is simulated using CST MWS software program. Microstrip line feeding technique with discrete port is used to feed the antenna. According to the results, S11 parameters of three resonant frequencies can be given as -15.08 dB, -11.88 dB and -24.03 dB at 2.39 GHz, 3.07 GHz and 4.92 GHz respectively. Gain values of the resonance frequencies can be given as follows, 2.25 dBi, 3.76 dBi and 1.92 dBi at 2.39 GHz, 3.07 GHz and 4.92 GHz respectively. Proposed antenna bandwidth can be given as, 197.5 MHz (2.29 GHz – 2.49 GHz) at 2.39 GHz, 116.1 MHz (3.01 GHz – 3.13 GHz) at 3.07 GHz and 266.2 MHz (4.79 GHz – 5.06 GHz) at 4.92 GHz, respectively. Since the designed antenna can work at 2.4 GHz and 5 GHz frequency bands with 2.24 dBi and 2.34 dBi, respectively, IEEE 802.11ac/b/g standards are supported by the antenna. So the proposed antenna can be used for Bluetooth and 2.4 GHz/5GHz WiFi applications.
