“…Some of these UWB antennas do not have simple structure (i.e., the radiators is etched on a substrate and placed vertically 0.5 mm above the ground plane [16]) and are not suitable to be integrated with associated UWB electronics. And the typical feeding techniques include slotted structures [17,18,20], CPW feeds [21,22], and simple microstrip lines [23,24,25]. Antenna operation is generally limited within the FCC defined UWB frequency range for these antenna designs.…”

Abstract-A novel inductively loaded monopole for future ultra-wideband (UWB) applications is presented. The antenna is compact and of small size (16 mm × 20 mm × 0.8 mm), and offer a very simple geometry suitable for low cost fabrication and straight forward printed circuit board integration. More specifically, the impedance matching of the classic printed inductively loaded monopole is improved by employment of the tapered microstrip feed line between K-connector and the printed monopole. By using this technique, impedance bandwidth (S 11 < −10 dB) from 3.03 GHz to over 40 GHz is obtained. Measured and simulated return loss curves are provided along with radiation patterns and gains, as a function of frequency. Compared to the recently reported UWB antennas, the presented antenna have smallest size, widest bandwidth, and simple configuration to realize the application in UWB communication systems. Furthermore, symmetric radiation patterns and satisfactory gains make the presented antenna a suitable candidate for practical UWB applications.

“…Planar antennas are suitable solutions to achieve low-cost and reliable radiating device for UWB systems, so some several work have been achieved in this area. A common approach is to use an UWB monopole with different shapes [3][4][5][6]; these monopoles are sensitive to ground dimensions. One solution is to take benefit from wideband feature of radiating apertures and combine it with planar technology to achieve UWB performance [2][3][4][5][6][7][8].…”

Abstract-In this paper, we present a new ultra wideband antenna design with band rejection for UWB applications. A CPW-fed circular patch radiates through a circular aperture, which ensures wideband impedance matching and stable omnidirectional pattern over an UWB frequency range, from 3 GHz to 10.6 GHz. In order to avoid interference with WLAN applications, at 5.8 GHz, the antenna is slightly modified to reject undesired band. A semi-circular slot ring is etched on the circular patch at the notch frequency, which creates an open circuit and avoids impedance matching and current propagation. A prototype was fabricated and measured, and the obtained experimental results agree with simulations and show an omnidirectional azimuth pattern over the entire bandwidth.

“…The antenna proposed in [2][3][4][5][6][7][8][16][17][18][19][20][21][22] provides a required impedance bandwidth and gain for UWB applications. In [2] the structure provides a good impedance band width but the level of cross-polarization especially at higher frequencies is considerably more in comparison to its co-polar component.…”

Abstract-In this paper a low cost, high gain, low cross-polar and compact edge feed printed elliptical antenna with a partial ground plane and parasitic patches is proposed and investigated. The proposed antenna is fabricated on a 1.6 mm thick FR4 substrate with dielectric constant of 4.4 and loss tangent of 0.025. The total planar area of the proposed antenna (L × W ) is 28 × 24 mm 2 . Both the simulated and experimental result shows that the proposed antenna provides a frequency range compatible with the ultra-wideband (UWB) standard, i.e., 3.5 GHz-12 GHz frequency band. The radiation pattern produced by the proposed antenna is approximately omnidirectional with inphase excitation of Surface waves resulting in less cross-polarization level (less than 20 dB) compared to its co-polar component for the entire impedance band width. The maximum measured gain for the fabricated antenna is around 6.27 dBi with an average efficiency of above 90% throughout the bandwidth. A linear phase response (phase of S 21 ) accompanied by a constant group delay of 1 ns throughout the measured bandwidth makes the proposed antenna a good candidate for UWB applications.
