“…The total dimension of the UWB antenna is optimized to a compact size of 20 × 24.5 mm 2 , which is smaller than other existing antennas of the literature [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][38][39][40][41][42] and is suitable for the applications in portable devices. In order to achieve the wideband operations and performance investigation of the proposed antenna configurations a fullwave, method-of-moment (MoM) code based commercially available electromagnetic simulator Zeland IE3D version 12 is used.…”

“…A CPWfed antenna not only attains a broad bandwidth, but also develops a smaller mutual coupling between adjacent lines [19,20]. However, the existing CPW-fed antennas are not suitable for portable UWB applications due to their big profiles [20][21][22][23][24][25][26][27][28][29][30]36]. Therefore, a wide field of research exists for the development of compact antennas with ultra wide bandwidth.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…The number of resonant frequencies for which computations are done is limited to three for brevity. The antenna current distribution in both cases is interpreted with respect to its performance as in [11]. It can be seen that the currents are concentrated along the lower edge of the radiating patch and the upper edge of the modified ground plane.…”

“…It has been shown by other researchers that many parameters including radius R , tapered angle θ, gap g between the disk and ground, and antenna total size a , b affect the impedance matching [2–4]. We performed simulation on these parameters and the trapezoid size w , h using an EM simulator software HFSS (Ansoft).…”
