A novel compact printed circular antenna for very ultrawideband applications

In this article, a compact design of the monopole antenna is proposed for the super‐wideband application (SWB). The extremely wide frequency bandwidth is achieved by deploying a topology based on trapezoid shape radiator, triangular tapered feed line, and semicircular ground. The antenna shows resonance from 1.42 GHz to more than 90 GHz with a bandwidth ratio of 63.30:1, VSWR ≤2 and with S11 ≤ −10 dB. The electrical dimension of the monopole antenna is 0.16λc × 0.27λc where the wavelength λc is with respect to the lowest cut‐off frequency. The designed monopole antenna is fabricated on the F4B substrate. The prototype is experimentally validated for ultrawideband and SWB application. The experimental and simulated results are in good agreement and the designed antenna shows better performance of a wideband operation, compact electrical dimension, and high bandwidth dimension ratio over existing reported structures. The proposed antenna can be used for multiple bands such are ISM, Wi‐Fi, WLAN, WiMAX, C, S, X, K, and Ku bands.

“…Nevertheless, for such a system, one of the major challenges is the design of a small size antenna while providing wide bandwidth, omnidirectional radiation pattern, stable gain, and small group delay variation. Usually, planar monopole antennas are popular due to the fact that they can easily be designed to provide above characteristics as well as light weight, low cost, and easy to construct [2,3]. In particular, a CPW-fed monopole antenna is most promising because of its attractive merits of simple uniplanar structure and ease of integration with the RF circuits.…”

“…More over, measured results of the fabri-cated prototype verified the proposed antenna has a nearly omnidirectional radiation pattern, stable antenna gain, and good timedomain characteristics, which satisfy the requirements of the current UWB wireless communication systems. In the last decade, intensive research has been made, especially in terms of designing new millimeter wave components operating over the V-band for high data rate wireless communications according to the IEEE 802.15.3c industrial standard [1][2][3][4].…”

opening is also shown. As expected, in this case, the performance degradation is highly mitigated. These results indicate that the transition bandwidth is highly affected by the diameter D and the stub length, and the performance is effectively improved as the diameter D increases. To minimize the performance degradation due to the parasitic resonance, both the open stub inductance and the parasitic capacitance should be minimized. For the diameter of D ¼ 2.2 mm, wideband performance with a return loss less than 10 dB up to 21.7 GHz is achieved.

“…The Federal Communications Commission allocated the frequency band 3.1-10. 6 GHz for the UWB services in 2002 [1,2]. However, over the designated UWB frequency band, there are existing WiMAX and WLAN operating bands such as the 3.5 GHz (3400-3690 MHz), the 5.2 GHz (5150-5350 MHz) and 5.8 GHz (5725-5825 MHz) bands that UWB devices may cause interference to [3,4].…”

Abstract-A compact ultrawideband (UWB) monopole antenna with two U-shaped slots for WLAN and WiMAX dual band-notched functions is proposed and experimentally studied. The proposed antenna with the size of 28 mm × 24 mm × 1.6 mm is excited by a 50 Ω microstrip feed line. The band-notch functions are realized by loading two approximate half-wavelength U-shaped slots which change the current distribution on the Y-shaped patch. The obtained results show that the designed antenna has an impedance bandwidth of 2.95 GHz-12 GHz for S 11 ≤ −10 dB, except two frequency stop-bands of 332 GHz-3.98 GHz for WiMAX and 4.81 GHz-6.68 GHz for WLAN. The antenna has successfully fabricated and measured. The return loss, band-notched characteristic, radiation patterns and peak gains are presented
