“…It is known that a uniform leaky-wave antenna (LWA) scans the beam in the off-broadside region (a region between

and

= 90

). Moreover, microstrip LWAs (MLWAs) are planar and low-profile antennas that can be easily integrated with millimeter-wave circuits [ 37 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 ]. Because of the desired radiation characteristics, we found that an LWA would be a simple yet effective solution for beam switching in the millimeter-wave band.…”

Beam-switching is one of the paramount focuses of 28 GHz millimeter-wave 5G devices. In this paper, a one-dimensional (1D) pattern reconfigurable leaky-wave antenna (LWA) was investigated and developed for wireless terminals. In order to provide a cost-effective solution, a uniform half-width LWA was used. The 1D beam-switching LWA was designed using three feed points at three different positions; by selecting the feeds, the direction of the beam can be switched. The antenna can switch the beam in three different directions along the antenna axis, such as backward, broadside, and forward. The 1D beam-switching antenna was fabricated, and because of the wide beamwidth, the measured radiation patterns can fill 128∘ of space (3 dB coverage), from θ = −64∘ to +64∘ at ϕ = 0∘. Following this, two of these antennas were placed at right angles to each other to achieve two-directional (2D) beam switching. The 2D beam-switching antenna pair was also prototyped and tested after integrating them into the ground plane of a wireless device. The antenna is able to point the beam in five different directions; moreover, its beam covers 167∘ (θ = −89∘ to +78∘) at ϕ = 0∘, and 154∘ (θ = −72∘ to +82∘) at ϕ = 90∘.

“…Wireless waves with different frequencies have different characteristics that could be more suitable for a certain type of wireless device [10][11][12]. Due to their large bandwidth, ability to integrate easily with microwave and millimetre-wave circuits, planar low-profile configuration, inherent beam-scanning abilities with frequency and narrow beam [13,14], microstrip LWAs continue to be a popular choice. The equation sin −1 (β/ko) gives the main beam's direction (θ) as measured from the boresight of a LWA, in which ko refers to the free-space wavenumber while β refers to the phase constant.…”

This paper provides an insight of a new, microstrip leaky wave antenna. It holds the ability to continue steer its beam at a swapping frequency. This is done with acceptable impedance matching while scanning and very little gain variation. Investigation is carried out on LWAs' control radiation pattern in steps at a band frequency via vertical and horizontal slots. The enhancement is realized by etching horizontal and vertical slots on the radiation element. This study also presents a novel half-width microstrip leaky wave antenna (LWA). The antenna is made up of the following basic structures group's vertical and horizontal slots. The reactance profile at the microstrip's free edge and thus the main beam direction is changed once the control-cell states are changed. The radiation pattern direction changes by sweeping the operating frequency between 4 GHz to 6 GHz.The main beam may be directed by the antenna between 15 o and 55 o. C band achieved the measured peak gain of the antenna of 10 dBi at 4.3 GHz beam scanning range.

“…Antenna signal transmission would also rely upon where the receiving antenna is found and what encompasses it [1,2,3]. With this in mind, an isotropic source can be utilized as a basis as it can be useful when it comes to closely emulating what is expected when designing an antenna.…”

As technological innovations improve over time, antennas have become an inherent piece of our everyday lives and it is essential for individuals to understand how data is moved through these devices. There are different methods of deciding how energy can be transmitted by antennas in an efficient manner, and not all things are seen on the antennas themselves, as there are a few issues that may emerge from the transmission cables that they are associated with too. A common method of deciding how an antenna can transmit signals of energy is through the analysis of its radiation pattern. The radiation pattern of an antenna is able to determine how energy is radiated or data is propagated by a particular antenna. This analysis will focus on understanding the graphs of radiation patterns, beam scanning, patterns of arrays, and other types of graphs. Understanding all of these concepts are important in order to have the ability to effectively utilize antennas such as being able to maximize the amount of distance possible when correctly positioned and also having the ability to boost signals from other devices.
