“…Here, these three characteristics were the assessment objects. Below is a description of the desirable output of these three key antenna characteristics:S11 indicates the power loss caused by the antenna, with less loss being better; −10 dB is a desirable value because it means only 10% of power is lost [8,9,10]. In this study, −9.25 dB (11.89% power loss) was aimed for to leave room for multiple parameter adjustments.…”

“…A key component of any radar sensor is its antenna. For UWB directional radar, previous studies have commonly deployed four types of antenna: microstrip disc [4,5,6,7], tapered slot [8], sinuous [9], and Yagi–Uda [10]. The microstrip disc antenna generates two main lobes [5], not just one, which makes it a bidirectional antenna instead of unidirectional, like the tapered slot, sinuous, or Yagi–Uda antennas.…”

“…These designs successfully eliminated the undesirable main lobe; however, side effects were introduced along the way, such as that the remaining main lobe’s direction became frequency dependent. On the other hand, the sinuous antenna design [9] is very complex when compared with the tapered slot antenna (TSA), involving multiple curvatures and angles. The Yagi–Uda [10] antenna design, although less complex than the sinuous (i.e., only needing to consider the shape of the segments and the distance between segments), still requires multiple segments and is more complicated than the tapered slot antenna.…”

Radar is a type of wireless, noncontact sensor that does not need to be placed on or near a test object for detection. A key component of any radar sensor is the antenna. Among different types of antennas, the linear tapered slot antenna (LTSA) is a wideband antenna that has the advantages of small size, design simplicity, and easy adaptation to an array. This study examined and analyzed the 10 primary parameters that define the LTSA design when operated in the ultra-wideband (UWB) frequency range. The study method involved varying each of the 10 parameters to discern how the variations impact the three critical characteristics of an antenna, namely, (1) return loss, (2) the far field radiation pattern on the E-plane, and (3) the far field radiation pattern on the H-plane. By analyzing the changes in these critical characteristics, a set of design recommendations for the 10 parameters was developed for the LTSA.
