roducing compact devices for space technology. Transparent antennas are seen as the solution to this problem. With the presence of a transparent antenna, it can save antenna installation space as its transparency properties allow it to be integrated with solar technology. However, the use of transparent material on the antenna causes the antenna gain to be low due to the low conductivity of the material. When a low conductivity material is used it also causes the antenna efficiency to decrease. Therefore, modifications to the antenna design are needed to overcome such problems. This study aims

Abstract:

The fifth-generation (5G) wireless communication system requires high gain antennas to support the growing demand for high-speed data transmission and low-latency connectivity. High gain antennas are crucial for enhancing the signal strength and extending the coverage area of 5G networks. By using multiple antenna elements, an array can achieve higher gain and directivity compared to a single element antenna. This improvement in gain enables better signal reception and transmission, leading to increased communication range, higher data rates, and improved reliability. In this paper, we discuss

Etching slots on the radiating elements and adjusting the serpentine microstrips influence surface current distribution and therefore effectively reduce antenna size and enhance antenna gain.

Abstract:

An array of monopole antennas over a ground plane that radiates a directive lobe in the end-fire direction are described in this paper. The design uses the rigorous method described by Drouet et al. 2008 in order to synthesize the radiation through the strong cumulative coupling between the monopoles. A gain higher than 20 dB was achieved in the end-fire direction over a 4.5% bandwidth. However, the antenna has been tilted in order to compensate the beam deviation caused by the edge diffraction. A prototype with 12 elements has been manufactured in order to validate the antenna principle and t

Abstract:

As metasurfaces are in the spotlight, research is being conducted to incorporate them into transmitarray (TA) antennas. Among these, as an attempt to create a low-profile design, a patch antenna classified as low-gain can be utilized as an appropriate source antenna. However, for high efficiency of the TA, the gain of the source antenna must be fundamentally improved. For this, a simple side metal structure was applied to a metallic cross-type slot transmitarray. This acts as a resonant element and reflector by utilizing the electromagnetic wave radiated from the source antenna. The changes in
