Design and analysis of a compact WiMAX and WLAN band notched planar monopole antenna for UWB and bluetooth applications

Abstract

In this manuscript, a compact UWB with dual band‐notched planar monopole antenna is investigated. The band notched characteristics at WiMAX and WLAN is obtained by connecting two pairs of stubs to the modified ground plane. The size of proposed antenna is 25(W) × 30(L) × 1.6(H) mm3 which consists of a fork shaped structure as a main radiating element and excited with a 50‐Ω microstrip line. The proposed antenna covers Bluetooth frequency band (2.4‐2.48 GHz) along with UWB spectrum without increasing the size of the antenna. The measured operating frequency of the proposed antenna is from 2.4 to 12.8 GHz along with WiMAX and WLAN band‐notched. Moreover, the measured gain of the proposed antenna varies between 2 and 6 dBi except notched band. At notched frequencies, it is −1 and −6 dBi at WiMAX and WLAN, respectively. The total antenna efficiency varies from 80% to 95% except notched frequency bands. The radiation patterns and time domain characteristics are also analyzed and found suitable for the modern UWB applications. Finally, a prototype of dual band‐notched antenna is manufactured and its characteristics are measured using network analyzer. The simulated and measured results are found in close agreement.

Sprocket gear wheel shaped printed monopole ultra‐wideband antenna with band notch characteristics: Design and measurement

“…It can be observed from the Table 2, that proposed antenna is compact in size and exhibit higher value of negative gain at both rejected frequency band as compared to the other references except reference. Also, the VSWR bandwidth of proposed antenna is more in comparison to references [30–36, 38, 39, 41‐43], except references [40,44,45]. While, the bandwidth (VSWR ≤2) of references [40,44,45] is better but the size of antenna designed in these references is large in comparison to the proposed UWB antenna.…”

New MIMO Antenna with Filtration for the Future Multiuser Systems in Satellite Communications

“…To do this, the antenna must be able to play the role of a band-cut filter. To meet such a requirement, various ultra-wideband filtered band antennas have been designed by adding slits or stray elements to or near the radiating element [5][6][7]. e use of metamaterial structures such as the split ring resonator seems to be a very promising solution to meet these needs due to their extraordinary properties.…”

“…However, it is still a major challenge to avoid interference with already existing bands in the UWB spectrum, such as WLAN (5.150‐5.825 GHz), Wi‐MAX (3.3‐3.6 GHz, 5.8 GHz), X‐band downlink, and uplink for satellite communication (7.25‐7.75 GHz, and 7.9 GHz to 8.4 GHz), C‐ band uplink and downlink for satellite communication (5.925‐6.425 GHz and 3.7‐4.2 GHz), and ITU‐R (7.725‐8.50 GHz) 3,4 . Thus, UWB antennas should possess band notch characteristics 5‐9 …”

[5][6][7][8][9] Multiple design techniques have been provided in the literature for achieving band-notch characteristics in the UWB antennas, that is, slot and parasiticelementloading, 10,11 using fractals, 12 embedding split-ring resonators (SRRs) and electromagnetic bandgap (EBG) structures. 1,3,[13][14][15][16][17] Further, Varactor diodes, PIN diodes, variable capacitors, optically controlled switch, magnetodielectric materials and microelectro-mechanical systems (MEMS) have been also used to achieve reconfigurable operation in UWB antennas with band-notch characteristics.…”
