“…Bow-tie antennas fed by coaxial line, stripline, and coplanar waveguides offer several benefits as UWB antennas, including low profiles, excellent radiation efficiency, ultra-broad impedance bands, and ease of construction. Because of their benefits, they are widely employed in a range of applications, including ground penetrating radars, mobile stations, and pulse antennas [ 76 , 77 ]. Detailed geometry and impedance calculations are in [ 78 ].…”

Over the previous two decades, a notable array of space exploration missions have been initiated with the primary aim of facilitating the return of both humans and robots from Earth to the moon. The significance of these endeavors cannot be emphasized enough as numerous entities, both public and private, from across the globe have invested substantial resources into this pursuit. Researchers have committed their efforts to addressing the challenges linked to lunar communication. Even with all of these efforts, only a few of the many suggested designs for communication and antennas on the moon have been evaluated and compared. These designs have also not been shared with the scientific community. To bridge this gap in the existing body of knowledge, this paper conducts a thorough review of lunar surface communication and the diverse antenna designs employed in lunar communication systems. This paper provides a summary of the findings presented in lunar surface communication research while also outlining the assorted challenges that impact lunar communication. Apart from various antenna designs reported in this field, based on their intended usage, two additional classifications are introduced: (a) mission-based antennas—utilized in actual lunar missions—and (b) research-based antennas—employed solely for research purposes. Given the critical need to comprehend and predict lunar conditions and antenna behaviors within those conditions, this review holds immense significance. Its relevance is particularly pronounced in light of the numerous upcoming lunar missions that have been announced.

This article presents the construction and examination of a Bow-Tie antenna array on a FR4 substrate. The proposed antenna geometry was chosen as a hybrid structure known as a semi-circled horn-like bow-tie antenna, and an array of four antennas in a single row was built. The semicircle diameter and the feedline length of a single antenna are 41.66mm and 21.44mm respectively. CST Microwave Studio was used for design and simulation. The proposed antenna array was printed on a 1.6mm thick substrate with a length of 325.00mm, a width of 56.00mm and a dielectric constant (ℇr) of 4.4. According to the experimental results, the proposed antenna has a return loss of-20.12dB at S11, a VSWR of 1.2 at S11 and Maximum Gain of about 2.94dB. The antenna array was tested in the 2.4GHz to 2.5GHz frequency range. The proposed semi-circled bow-tie antenna array was compared to the rectangular bow-tie antenna array, and it was observed that the proposed antenna array has outperformed the rectangular bow-tie antenna array at 2.45GHz. As a result, the proposed antenna array is a suitable candidate for Mobile and Amateur Radio Applications.

“…The return of loss value of -10 dB is generally acceptable since this value renders a significantly reduced reflected wave compared to the transmitted wave. This value also becomes a reference point to determine whether the antenna can work at the desired frequency [20].…”

Automatic dependent surveillance-broadcast (ADS-B) is an equipment of a radar system to reach difficult areas. For radar applications, an ADS-B requires a low noise amplifier (LNA) with high gain, stability, and a low noise figure. In this research, to produce an LNA with good performance, an LNA was designed using a BJT transistor 2SC5006 with DC bias, VCE = 3 V, and current Ic = 10 mA, also a DC supply with VCC = 12 V, to achieve a high gain with a low noise figure. The initial LNA impedance circuit was simulated using 2 elements and then converted into 3 elements to obtain parameters according to the target specification through the tuning process, impedance matching circuit was used to reduce return loss and voltage standing wave ratio (VSWR) values. The LNA sequence obtains the working frequency of 1090 MHz, return loss of -52.103 dB, a gain of 10.382, VSWR of 1.005, a noise figure of 0.552, stability factor of 0.997, and bandwidth of 83 MHz. From the simulation results, the LNA has been successfully designed according to the ADS-B receiver specifications.
