design using CST Software 2019. The innovative aspect introduced in this study involves placing a polyethylene substrate in front of the flexible antenna that was originally designed on a textile substrate. This addition serves the purpose of safeguarding the flexible antenna from environmental factors, especially during rainy conditions. When the antenna gets wet, it changes its properties and characteristics, primarily due to alterations in the dielectric constant. As a result, the polyethylene substrate is applied to prevent moisture absorption. The research presents simulation results, including data on return loss, radiation patterns, and axial ratio in both 2-D and 3-D formats. This research introduces an innovative design for a flexible antenna array intended for wireless applications. The antenna is simulated with CST software and is specifically aimed at creating a body area network operating at a single frequency band of 12.3 GHz. The substrate material for the antenna is denim jeans, with a dielectric constant of 1.7. It is covered with a layer of polyethylene substrate, which has a dielectric constant of 2.25 and incorporates a conductive element made from copper tape. The physical dimensions of the antenna board are 60x40 mm. The designed antenna offers a relatively wide bandwidth of 44.8%, spanning the frequency range from 12GHz to 12.55GHz, making it suitable for the intended purpose. This kind of bandwidth is considered optimal for this antenna. The proposed single-band antenna design is versatile and wellsuited for use in multiband applications and wearable devices within wireless body area networks (WBANs). It's important to note that antennas featuring multiple identical patches are commonly referred to as array antennae.
The performance of these systems primarily hinges on the quality of the integrated antenna. Flexible wireless technologies call for the inclusion of adaptable, lightweight, compact antennas with a low profile. At the same time, these antennas should be highly efficient, effective with reasonably broad bandwidth, and exhibit favorable radiation characteristics, as indicated in references [5-11]. In this research, a 2-diamond shape with a 2-L cut shape flexible antenna which is an array antenna designed on the material having a dielectric constant of 1.7 known as Jeans covered with polyethylene substrate that has a dielectric constant of 2.25 and saves the antenna from aging-relatedlosses.
1.1 Array Antenna An array antenna that consists of two or more identical patches refers to a configuration where multiple antenna elements, typically of the same size and shape, are placed near form a collective antenna system. These identical patches work together to achieve specific radiation characteristics and beamforming capabilities. When multiple patches are used in an array, they can be individually controlled in terms of phase and amplitude to create desirable radiation patterns, such as steering the main lobe in a particular direction or improving signal reception and transmission in specific areas. The coordination and manipulation of these identical patches enable the array antenna to exhibit enhanced performance, directivity, and gain for various applications, including in wireless communication systems and radar systems.
