“…5 and 7 GHz. Once these two basic structures have been optimized, various broadbanding techniques were used to achieve UWB characteristics [22] and to compensate for the impedance mismatch created by the inductances of the microstrip and coaxial feed [23]. The effect of each broadbanding technique is studied by evaluating the antenna's basic performance parameters, i.e.…”

A design overview for a microstrip antenna topology operating within the full UWB band is described. Existing broadbanding concepts have been creatively combined throughout this design to enable the UWB behavior, while simultaneously keeping the full ground plane intact. This is crucial in maintaining worn antenna performance. It successfully reduces any on-body performance degradation, resulting in a very robust structure. A detailed numerical and experimental evaluation of the antenna is performed in free space and on body.

“…They are widely used in a multitude wireless communication applications. However, the obvious disadvantage of the microstrip antenna is its limitations in terms of bandwidth . The recent introduction and future use of multiple wireless standards within the 2 to 3 GHz band has renewed the intensity of research on wideband antennas for this band.…”

A wideband microstrip-based wearable antenna with a fractional bandwidth of 51% is designed using textile materials for wearable applications. The antenna operates between 2 and 3 GHz with low back-radiation to ensure minimum coupling to the body and reduced electromagnetic power absorption in the human tissue. The behavior microstrip antenna topology, which is narrowband in nature, is altered via the combinations of various broadbanding techniques, while maintaining the existence of the full ground plane backing. This ensures that the antenna radiation is directed outward form the body to efficiently propagate wireless signals toward other off-body nodes and base stations. Simulation and measurement results indicated that the use of this microstrip topology with multiple broadbanding techniques is capable of reducing the back lobe, resulting in a front-to-back ratio of about 17 dB and a 3.5 dBi of average gain.

“…After a large amount of research, a wide variety of band notch antennas have also appeared in people's field of vision. At present, the commonly used methods to generate notch in the operating frequency of a antenna are grooving, adding open branch, resonator, parasitic unit, and mixing various notch technologies [5][6][7][8][9][10][11][12][13][14].…”

A novel ultra-wideband (UWB) printed monopole antenna with triple band-notched characteristics is proposed in this paper. The antenna bandwidth is extended by grooving on the connecting floor and increasing the impedance transformation line, with antenna bandwidth of 3.0∼11 GHz and relative bandwidth of 114%. The overall antenna size is 35 × 30 mm 2 . The complementary split-ring resonators (CSRRs) are loaded on the UWB antenna patch with microstrip wire feed. A symmetric J gap is loaded on the bottom plate, and the spiral gap is loaded on the feeder. The triple band-notched characteristics at 3.22∼3.97 GHz, 4.94∼5.84 GHz, and 7.25∼7.86 GHz bands are realized. The gain of the designed antenna in the notch frequency segment can be reduced rapidly to −4 dbi, while the gain of other frequency bands is above 2 dBi. Simulated and measured results show that the antenna has stable gain and good radiation characteristics in the UWB frequency range.
