“…In some reported designs band-notched characteristics was achieved by inserting different types of slots on the radiating patch or associated ground plane [10][11][12][13][14][15][16][17][18][19][20][21][22][23]. Addition of parasitic elements near the printed antennas and use of defected ground structure or electromagnetic band gap had also been reported to achieve notched frequency band [24][25][26][27][28][29][30][31][32][33].…”

Abstract-In this paper, a compact ultra-wideband microstrip-fed annular ring antenna with band notch characteristics for wireless local area network (WLAN) and dedicated short-range communication (DSRC) is proposed. The proposed antenna comprises an annular ring patch and a partial ground plane with a rectangular slot. The notched frequency band is achieved by etching a partial annular slot in the lower portion of the ring radiator. The centre frequency and bandwidth of the notched band can be controlled by adjusting the width and position of the annular slot. Measured results show that the proposed antenna achieved an impedance bandwidth of 3-10.6 GHz with a notched frequency band centred at 5.5 GHz. Compared to the recently reported band-notched UWB antennas, the proposed antenna has a simple configuration to realize the band notch characteristics to mitigate the possible interference between UWB and existing WLAN & DSRC systems. Furthermore, a symmetric radiation patterns, satisfactory gain and good time domain behaviour except at the notched frequency band makes the proposed antenna a suitable candidate for practical UWB applications.

“…The common and simple method is to insert the band rejection elements on the radiation patch of the UWB antenna. This would include various shape slots or parasitic elements [2][3][4][5][6][7][8]. The multi-band rejection UWB antennas have also been recently reported on some authors [9][10][11][12][13][14][15][16][17][18].…”

Abstract-In this paper, the design method of a quadruple-band rejection ultra-wideband (UWB) antenna with three co-directional complementary split ring resonators (CSRRs) is proposed. Within the design step, individual antennas corresponding to each rejection band is first designed, and then a finalized structure is determined by assembling these individual antennas altogether. The shape of the final antenna achieves both the impedance matching of ultra-wideband and the respective resonances at four rejection bands. Here, the mutual coupling among the band rejection elements is minimized, and the placement of the resonators is optimized. The fabricated antenna is compact enough to be integrated into the UWB system, and also the measured results show the validity of the proposed design strategy.

“…In order to operate as such systems, the antenna must be in small size and provide better performances than antenna operating in free space environments [6][7][8][9][10][11]. Based on the previously reported research works, printed monopole antenna has become a major field of interest due to its compact size, omni-directional radiation patterns, large bandwidth (BW) and high radiation efficiency [12][13][14][15][16][17][18][19][20]. The printed monopole antenna has therefore been chosen for WiBAN application, due to the aforementioned characteristics.…”

Abstract-Wireless implantable body area network (WiBAN) is useful for monitoring vital human parameters in medical diagnosis such as breast cancer, heart attack and high blood pressure. The main objective of this paper is to design a small printed monopole antenna for WiBAN applications at 6.0 GHz. The small implantable antenna was tested in a lossy environment by being submerged into canola oil that mimics the dielectric properties of human breast fat tissue. The antenna performances were measured by using vector network analyzer (VNA) in order to evaluate the return loss and operating bandwidth of the antenna. The other parameters such as efficiency, radiation pattern and gain are evaluated by simulation of CST Studio 2012 software. When compared, there is good agreement between the simulation and measurement results. The simulated antenna gain and efficiency are 5.8 dBi and 97%, respectively, when submerged into canola oil. The antenna radiation pattern is directional, and it has 6 lobes implying its coverage in more directions which is of good benefit due to body movement. The antenna's polarization was tested by placing a wideband antenna at several degrees around the proposed
