A novel compact CPW‐fed planar monopole antenna with modified stair‐style ground for ultra‐wideband applications

Abstract

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.

A dielectric resonator based line stripe miniaturized ultra‐wideband antenna for fifth‐generation applications

“…The patch may be rectangular, circular, heart shaped, elliptical, and so forth. The antenna performance also can be improved by manipulating the ground structure 8–11 . In Elwi et al, 12 a miniaturized slotted open mouth flower patch UWB printed monopole antenna with hard surface (HS) arrays has been proposed.…”

“…The antenna performance also can be improved by manipulating the ground structure. [8][9][10][11] In Elwi et al, 12 a miniaturized slotted open mouth flower patch UWB printed monopole antenna with hard surface (HS) arrays has been proposed. The HS array is used to ensure omni radiation pattern over a wide frequency range to meet the radio frequency (RF) harvesting requirements of Internet of Things (IoT) applications.…”

Miniaturized Spectacles Shaped Tapered Slotted Patch Antenna for UWB Applications

“…The properties of the ultra-wideband (UWB) antennas can be improved also by changing the patch shape (rectangular, elliptical, circular, heart-shaped). Wider bandwidth can be also achieved by reducing dimensions of the ground plane [4]- [7]. Over the past decade, numerous antennas have been proposed for UWB applications.…”

A novel heart‐shaped monopole antenna for UWB and RFID applications

“…[4–7]. Many planar monopole antennas change the ground structures to achieve wide impedance bandwidth and omnidirectional radiation pattern [8, 9]. In this article, a heart‐shaped monopole antenna is designed, which can provide about 9 GHz (from 2.1 to 11.5 GHz) impedance bandwidth ( S 11 <−10dB) with simple, low cost and compact size, so that the proposed antenna can not only cover the UWB frequency range but also cover the 2.4 GHz, which is used for radio‐frequency identification (RFID) systems and other wireless communication systems, and meanwhile, the antenna can achieve omnidirectional radiation at 2.4, 4, 5.8, and 9 GHz.…”
