“…The design of notch frequency can be adjusted by controling the current patch on the microstrip line, which is more simple and convenient. The size of the proposed antenna is 24 mm Â 12 mm, which is smaller than that of the relevant works in [2,4,6,7,8,9,10,11,12,13,14,15,16]. The ratio of the −3 dB bandwidth to the −10 dB bandwidth is 1.038, which is very close to 1.…”

“…Hence, a UWB antenna with filter function is of great importance in reducing both the size and cost of the UWB system. To the best of our knowledge, most of the UWB antenna designs focus on the minimization technology [5], band-notched characteristics [6,7,8] and other antenna performances, such as high gain and wide bandwidth [9,10,11]. However, the band-edge selectivity and the size of these antennas are not satisfactory.…”

A compact filtering UWB antenna with band-notched function is proposed. The proposed antenna mainly consists a stepped impedance resonator feeding line with low-pass characteristic at the top of the dielectric substrate and two slots at the bottom. The stepped impedance resonator is used to enhance the upper band-edge selectivity, and the narrow slot near the stepped slot is employed to improve the lower band-edge selectivity. What's more, two microstrip lines paralleling to the feeding line are located at the end of the slot, which can generate the notch band by controlling the length of the current path in two microstrip lines. Compared with the traditional antennas, the proposed antenna is not only smaller in size, but also has better suppression of the in-band and out-of-band interference signals in function.

“…10 Dual-sided open circuit stubs were employed to obtain an enhanced gain while rejecting image frequencies. 11 The initial motivation for obtaining added gain in the bow-tie antenna described here is due to its role as a scattering target in our active investigation of multistatic detection for smart far-field wireless power transmission. [12][13][14] This work employs a multistatic detection technique involving time-reversal and pulse inversion to permit nonlinear targets, formed by connecting a passive rectifier to an antenna (to form a rectenna), to be located and distinguished.…”

A novel ultrawideband planar bow‐tie antenna with curved directive strips for gain enhancement is presented. The strips direct radiation to the plane perpendicular to the antenna, increasing the broadside gain over the antenna's impedance bandwidth with no increase to the radius of the sphere containing the antenna. To facilitate the use of the proposed antenna in various application scenarios, three different feeding mechanisms are presented. Accordingly, three antennas, each with their respective feeding structures are designed and tested via simulation and measurement with the results for each showing enhanced broadside gain over the antenna bandwidth.

A novel broadband bow-tie antenna with high-gain performance throughout the operating band is proposed and investigated in this article. This folded sectorial bow-tie antenna is fed by a Г-shaped strip balun, and the electromagnetic coupling feed mechanism is easy to optimize the impedance matching. The study of proposed antenna performance with different geometric parameters has been conducted. The final design is fabricated and measured, and the results exhibit a good impedance bandwidth of approximately 93.3% for VSWR≤2 ranging from 1.35 to 3.71 GHz, stable gain of 8.43-10.02 dBi, and unidirectional radiation patterns over the whole operating band. Broadband coverage, stable high-gain performance, and the simple structure make this antenna an excellent candidate for wireless communication systems.
