“…The ratio between the two power density levels serves as a measure of gain. A term known as "antenna gain" can be used to describe the amount of power transferred in the direction of peak radiation from an isotropic source [40]. The term "directivity" refers to the ratio of the radiation intensity in a particular direction emanating from an antenna to the radiation intensity that has been averaged out over all directions [38].…”

“…The amount of power supplied to an antenna and the intensity with which it emits or dissipates can be used to determine how effective the antenna is. Most of the energy sent to the low-efficiency antenna is either lost due to losses within the antenna itself or because of an impedance mismatch that causes it to reflect away [40].…”

Recently, microstrip patch antennas have become popular. Due to their ubiquity, these antennas have more uses every day. In this research paper, a 2.45 GHz microstrip patch antenna has been reviewed and analyzed. Different substrate materials have been used to make these antennas, and their thickness is different. Various antennas are designed based on the application, such as rectangular, square, triangle, ring, donut, and dipole. Other types of software were used to design the antenna, including CST, HFSS, MATLAB, ADS, and FEKO. Microstrip patch antenna design is a relatively new field of study for wireless applications. Several devices are linked to send or receive radio waves using a single antenna. Antennas designed for 2.45 GHz are used in various wireless communication systems, including television broadcasts, microwave ovens, mobile phones, wireless local area network (WLAN), Bluetooth, global positioning system (GPS), and two-way radios. This article looks at the geometric structures of antennas, including their many parameters and materials and the many different shapes they can take. In addition, the substrate materials, the loss tangent, the thickness, the return loss, the bandwidth, the voltage standing wave ratio (VSWR), the gain, and the directivity of previous articles will also be discussed.

“…[2][3][4][5] The first integration of Chinese characters into antenna design was the "Wang" linearly polarized patch antenna proposed in 2010. 6 After that, the design of a single fed "Wang" patch antenna with linear polarization [7][8][9] and circular polarization 10,11 was studied. Recently, more patch antennas have been realized by using other single Chinese characters, such as the Meng patch 2 and Guo patch 3 for circular polarized radiation.…”

In this paper, a Chinese character-shaped artistic multiple input multiple output (MIMO) antenna with H-shaped defect ground structure (HDGS) is designed and analyzed. The H-shaped structures are loaded on the ground along the outer edge of patches to make it a part of the coupling current propagation direction. The two-element MIMO antenna is placed on the substrate with a separation of only 0.024 λ 0 (λ 0 is the free-space wavelength at 2.458 GHz). The designed MIMO antenna without HDGS has 10.4 and 7.2 dB higher isolation than E-and H-plane rectangular array antennas. After loading HDGS, the isolation reaches 23.86 dB at 2.458 GHz, and the center frequency is not offset. The achieved bandwidth is within IEEE 802.11 at a 2.4-GHz wireless local area network band. Meanwhile, the isolation is higher than 20 dB in the 10-dB impedance bandwidth (2.447-2.468 GHz). Moreover, the radiation pattern remained basically unchanged.

“…The idea of making radiating patches into the shape of the Chinese character “王” was first proposed in 2010 . Subsequently, there is more and more research on the linearly polarized, circularly polarized and the antenna array of the Wang‐shaped antenna . In Reference , a reconfigurable Meng‐shaped patch antenna with unidirectional circular‐polarization is designed.…”

This article presents the Gui-shaped Chinese character array antenna (GCCAA), which is loaded with the L-shaped defect ground structure (LDGS) to improve isolation between the antennas. The GCCAA is obtained by arranging two Tu-shaped antennas up and down. By etching a pair of LDGS on the ground, the direction of the coupling current is changed on the ground. Most importantly, the LDGS is not etched in the middle of the antenna elements, but loaded along the outer edge of the GCCAA, which not to destroy the appearance of the GCCAA and maintain the compact nature of the Chinese character. The measured results show that LDGS improves isolation from 15.4 to 37.4 dB when the antennas are placed with a 0.065 λ 0 edge-to-edge distance. Meanwhile, it has little influence on reflection coefficient and radiation patterns. The decoupling technique is simple and straightforward which can be easy applied in Chinese character array antenna.
