“…The additional parameters provide finer controls on HPBW and side lobe level but come at the cost of antenna gain. For example, the baseline model of this study (shown below) has a gain of 10.68 dB, which is better than the antipodal Vivaldi antenna designed by Osman et al [12] (gain of 4.3 dB) or Moosazadeh and colleagues [13,14] (gain of 8.5 dB). It is also better than the Vivaldi antenna designed by Zhang et al [15] (gain of 6.7 dB) or Kerati et al [16] (gain of 8 dB).…”

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.

“…The proposed Vivaldi antenna has a higher bandwidth than the obtained bandwidth in [5], [10,11] and [14]. Also, the proposed Vivaldi antenna can reduce the antenna size by 23% and 162.3% compared to those in [12,13] and in [15], respectively. Table 1 indicates the comparison between these different UWB Vivaldi antennas.…”

“…The maximum gain of 5 dB can be obtained in the band of 2.96-5.05 GHz, while a maximum gain of about 6.5 dB can be achieved in the band of 5.58-8.52 GHz. In [15], an antipodal Vivaldi antenna with elliptically tapered radiators is presented to provide a bandwidth of 1.65-18 GHz. In this paper, the proposed novel Vivaldi antenna provides a higher gain than that of the conventional Vivaldi antenna of the same size.…”

In this paper, the radiation characteristics of the conventional Vivaldi antenna are improved by proposing a novel design of a Vivaldi antenna. This proposed Vivaldi antenna is excited through three slots by using the L-probe microstrip feeder. The novel design can provide higher gain and wider bandwidth compared to that of the conventional Vivaldi antenna of the same size. The CST MWS software is used to simulate the proposed Vivaldi antenna. The measured and the simulated S-parameters were compared so that the feasibility of the proposed Vivaldi antenna was validated. The measured S-parameters show that the impedance bandwidth of the proposed Vivaldi antenna was from 1.976 to 7.728 GHz, while the measured maximum gain is 4.9 dBi at the operating frequency of 3 GHz.

“…To extend the lower end frequency of operation and increase the gain of the antenna, the comb structure of Fig. 3 e) includes multiple quarter-wave transformers added to the Vivaldi taper [26]. This blocks electric field modes that may propagate along the edge of the PCB, improving the impedance match and directivity across a large frequency band [27].…”
