“…It can be seen that the antenna gain is about −3 ∼ 1 dBi at 3 ∼ 6 GHz, and quickly increases to 3 dBi at 8 GHz, and remains around 3 ∼ 5 dBi from 8 GHz to 40 GHz. Generally speaking, the measured and simulated gains are similar to those presented in [25][26][27][28] over most parts o the bandwidth.…”

“…Fortunately several techniques have been reported in the literatures and presented concept may prove to be helpful. Techniques include tapered microstrip line [26], and microstrip transitions line [27]. In addition, other important antenna design goals include miniaturization, minimal dispersion effects and minor group delay variations, constant gain values as a function of frequency, good impulse response in the time domain, and in some cases, general omnidirectional radiation behavior.…”

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.

“…Regarding the modifications of the ordinary circular monopole antenna shown in Figure 1(a), by introducing a simple microstrip transition between the feedline and the printed circular disc as shown in Figure 1(b), the impedance bandwidth of the planar monopole can be extended as explained in detail in [32]. Loading a block with triangular shape slot on both sides of the ordinary circular patch as shown in Figure 1(c) provides wider impedance bandwidth than the antennas shown in Figures 1(a) and 1(b).…”

Abstract-This study presents a novel technique for designing an ultra-wideband (UWB) filteringantenna with dual sharp band notches. This design is composed of a modified monopole antenna integrated with resonant structures. The monopole antenna is modified using microstrip transition between the feedline and the patch. In addition, block with a triangle-shaped slot is loaded on each side of the ordinary circular patch to produce wide bandwidth with better return loss and higher frequency skirt selectivity. The resonant structures are constructed using two double split ring resonators (DSRR) loaded above the ground plane of the antenna to produce dual band notches and filter out WiMAX (3.3-3.7 GHz) and HiperLAN2 (5.4-5.7 GHz) frequencies. The band notch position is controlled by varying the length of the DSRR. The reconfigurability feature is achieved by using two PIN diode switches employed in the two DSRR. The measured results show that the proposed filtering-antenna provides wide impedance bandwidth from 2.58 to 15.5 GHz with controllable dual sharp band notches for WiMAX and HiperLAN, peak realized gain of 4.96 dB and omnidirectional radiation pattern.

“…Various coplanar waveguide (CPW) and microstrip fed antennas are designed and small ground plane are used to augment the bandwidth of the antenna. Advantages of CPW fed antenna is wider bandwidth, less dispersion loss and lower radiation leakage as compare to microstrip and probe fed technique [8][9][10]. In studies, many methods have been developed to design multiband antenna by using slot loading technique and design of notch frequency band such as cutting slots into the ground plane or into the antenna radiators [11][12][13][14][15].…”

A microstrip antenna with a circular disc design and modified ground is proposed in this paper. Circular shapes of different size have been slotted out from the radiating patch for achieving extended ultra wideband (UWB) with GSM/Bluetooth bands with maximum bandwidth of 17.7 GHz (0.88-18.6 GHz). Further, characteristic of dual notch band is achieved, when a combination of T and L-shaped slots are etched into the circular disc and ground plane respectively. Change in length of slots is controlling the notch band characteristics. The proposed antenna has rejection bandwidth of 1.3-2.2 GHz (LTE band), 3.2-3.9 GHz (WiMAX band) and 5.2-6.1 GHz (WLAN band) respectively. It covers the frequency range of 0.88-18.5 GHz with the VSWR of less than 2. Also, an equivalent parallel resonant circuit has been demonstrated for band notched frequencies of the designed antenna. The gain achieved by the proposed antenna is 6.27 dBi. This antenna has been designed, investigated and fabricated for GSM, Bluetooth, UWB, X and Ku band applications. The stable gain including H & E-plane radiation pattern with good directivity and omnidirectional behavior is achieved by the proposed antenna. Measured bandwidths are 0.5 GHz, 0.8 GHz, 1.1 GHz and 11.7 GHz respectively.
