“…In another technique a planar monopole antenna [2] for new generation mobile and lower band ultra-wide band applications was designed to operate from 1.5 GHz to 5.5 GHz with 114.3% impedance bandwidth. An Ultra-wideband antenna differential wideslot antenna with improved radiation patterns and gains is reported in [3]. Its overall size was optimized to 33.6 mm×29.6 mm×0.635 mm and with the gain values from 1.3 dBi to 4.7 dBi.…”

Abstract-This paper proposes two rectangular ring planar monopole antennas for wideband and ultra-wideband applications. Simple planar rectangular rings are used to design the planar antennas. These rectangular rings are designed in a way to achieve the wideband operations. The operating frequency band ranges from 1.85 GHz to 4.95 GHz and 3.12 GHz to 14.15 GHz. The gain varies from 1.83 dBi to 2.89 dBi for rectangular ring wideband antenna and 1.89 dBi to 5.2 dBi for rectangular ring ultra-wideband antenna. The design approach and the results are discussed.

“…Planar printed monopole and dipole antennas [1][2][3][4][5][6], especially with the multi-band characteristics, are promising candidates in wireless portable communication systems in virtue of their low profile, light weight, large service area and easy fabrication. To realize multiband operation, ultra-wideband (UWB) monopole antennas with bandnotched characteristics by using meander lines [1] and arc-shaped stubs [2] are proposed. Differently, the multiband behavior has been obtained by extending the geometry of a reference shape adding Tshaped strips [3,4], Y-shaped stubs [5] or mirrored-L elements [6].…”

Abstract-A circular patch antenna based on open elliptical-ring slots and shorting vias with conical radiation patterns is proposed. Fed by the coaxial probe at the center of the circular patch, the proposed antenna is excited at three resonant modes, simultaneously. The first resonant mode (monopolar patch mode) is achieved by six shorting vias, each of which is placed at the center of the open elliptical-ring slot. By embedding six open elliptical-ring slots on the patch, the other two resonant modes of the open elliptical-ring slot resonator, TE 110 and TE 210 , can also be excited. Due to symmetrical slots on the patch, these two modes can produce conical patterns, and their frequency ratio can also be tuned by adjusting the size of the slots. The proposed antenna is fabricated and measured. The measured results show that the proposed antenna can provide three operating bands which meet the required bandwidth specifications of 2.4/5.8 GHz WLAN and 3.5/5.5 GHz WiMAX standards. Detailed design considerations of the proposed antenna are described, and both the simulated and measured results are given. Moreover, the effects of the vital parameters on the performance of the proposed antenna are analyzed in this paper.

“…have been tried in literature. Varying feed techniques/structures like double feed [6], trident feed [7], meandering feed [8], T shaped stub [9], 3 offset stub [10], fan shaped stub antenna [11] have also been tried in past to enhance the antenna bandwidth. Antenna band width enhancement have also been reported in literature by the variation in ground plane shape like notched ground [12], saw tooth ground [13], rounded CPW ground [14], tapered CPW ground [15], coaxial line [16] etc.…”

“…But there is a probability that UWB user in WiMax, WLAN environment may be effected [17] with high signal transmission level of WLAN/WiMax. In efforts to reduce the interference from narrow band systems [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] meandered ground stubs have been used [18][19] to notch single, dual-band or Triple band. Further, by making slots in ground, bands from 3.3 to 3.7GHz, 3.7 to 4.2 GHz and 5.2 to 5.8 GHz have been notched to overcome electromagnetic interference [20], but they suffers from gain uniformity, impedance bandwidth etc.…”

In this paper, a rectangular inset feed microstrip antenna with defected ground plane for UWB application is presented. It is found that by making symmetrical T-shape slots just beneath the radiating patch in the ground plane results UWB characteristics. Parasitic effect is minimized by optimization in the shape of slot like width and length, so that uniform return loss is obtained in the entire UWB range. The simulated and fabricated antenna design shows return loss below -12 dB and voltage standing wave ratio below 2 in the entire UWB range. A very wide impedance bandwidth of 11.2 GHz at -10dB return loss has been obtained.Further, band notching property to avoid the signal interference from existing WiMax system in the environment has been obtained by varying ground structure. The effect of first T-cut slot in ground structure has been observed to result band notching from 3.28 to 4.58 GHz. Therefore, the proposed antenna overcomes the signal interference problem with existing WiMax IEEE 802.16 system and can be suitably used for UWB application.
