“…To evaluate the capability of water as a mutual coupling reducer, the antenna without the water decoupling mechanism is used as the reference structure. [33] Then, a network analyzer is used to determine the port scattering parameters. A comparison is made of various scattering measurements for S 11 and S 12 parameters that is shown in Figure 11.…”

Herein, a new method for minimizing mutual coupling of an antenna array with confined water is proposed. In multiantenna systems, mutual coupling reduction is needed to sustain array signal processing efficiency. There are currently a variety of ways to suppress coupling, including defected ground, electromagnetic (EM) bandgaps, and advanced structures. The water absorption characteristic is devised in this innovative approach to minimize mutual coupling without a permanent alteration in the structure. Surface current between two antennas is cancelled using permittivity and water depth in a new configuration. A plexi‐glass confined water is added between the propagating elements to achieve this aim. The rectangular microstrip patch of transparent conducting components serves as the antenna array. Using scattering theories, numerical EM calculations, and anechoic chamber tests, the suggested technique shows a 15 dB decrease in coupling at center frequency (7 GHz). Other propagating functions have also been improved. The suggested framework can be used in multifunction communication networks, aerial vehicle antennas, solar panels, and naval communications because of its optical transparency.

As the development of vastly incorporated systems for both electronic warfare (EW) and communication-oriented uses advances, compact, lightweight, and wideband, antennas appear to become increasingly important for unmanned aerial vehicle (UAV) platforms. An empirical evaluation of a small printed passive wideband dipole antenna is presented in this article. The main advantages of this design are that it reduces the antenna's height and weight while keeping the architecture as sturdy as possible from an environmental aspect, with the only drawback being a reduction in voltage standing wave ratio (VSWR) efficiency. UAVs are increasingly being used for commercial, agriculture, and military purposes. For communication and navigation, UAVs require small, lightweight antennas. Omnidirectional antennas are extensively used in UAV systems. A UAV's mission is to collect and send accurate data in real time to base stations. As little more than a result, maintaining a stable Wi-Fi connection is essential. Horizontally polarized (HP) antennas might be able to provide polarization variety for secure wireless communication and navigation. HP omnidirectional antennas have been developed in large numbers. Both of these HP antennas, however, do not function in multiband mode. Only two publications on dual-band HP omnidirectional antennas have been found in periodicals to our knowledge. The feed network for two vertically stacked omnidirectional components in a wideband omnidirectional antenna array is explained. [1] The antenna has an 18% impedance and emits monopole-like radiation characteristics. Circular patch antennas and circularly periodic mushroom units make up the antennas. [2] Unfortunately, the majority of monopole antennas have such a high profile and a low-elevation angle radiation pattern, making them unsuitable for large metallic vehicle communication. UAVs have gotten a lot of press for military, industrial, and scientific uses. [3] An antenna for UAV applications should get a low profile to reduce air resistance, as well as small size, and also be lightweight. [4] An antenna for UAV applications should get a low profile to reduce air resistance, as well as small size, and just be lightweight. [5] As a low-profile antenna with an omnidirectional radiation pattern, a segmented loop antenna was investigated. [6] Although capacitive interaction between several segments causes an in-phase current, a segmented loop antenna has an omnidirectional radiation pattern. The antenna size and

“…For the second type of scattering, there are many ways to realize RCSR, such as polarization conversion metamaterial (PCM), [6][7][8] frequency selective surface (FSS), 9,10 artificial magnetic conductor (AMC), [11][12][13] and PGM. [14][15][16][17][18] Considering the scattering problem of the antenna, at present, achieving the in-band RCSR of the antenna is an urgent problem to be solved.…”

In this letter, a low in-band radar cross section (RCS) antenna with radiation and scattering characteristics based on phase gradient metasurface (PGM) is proposed. The proposed structure consists of periodic arrays of metallic patches printed on a 1.2 mm dielectric substrate with a metallic ground plane, and the RCS is reduced between 7.8 and 12 GHz under normal incidence. Without increasing the structural complexity, some units on the metasurface are used directly as the radiators of the antenna array, which maintains the radiation characteristics of the antenna and reduces its RCS in the working band. The performance test for metasurface antenna agrees well with simulation.phase gradient metasurface (PGM), in-band radar cross section (RCS), microstrip antenna
