“…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

“…However, band-stop filter increases the circuit dimension. A simpler way by which we can solve the problem is by cutting slots on the patch or ground plane [5][6][7][8][9], putting parasitic elements close to the radiator [10][11][12][13], using a tuning stub [14], embedding quarter-wavelength tuning stub in a circular ring monopole [15], embedding resonant cell in the microstrip fed line [16] and utilizing a small resonant patch [17]. The designs of UWB antenna have been reported where sub wavelength structures as SRR [18] and electromagnetic band gap structures [19] are used to create notch bands.…”

Abstract-A novel planar ultra wideband (UWB) antenna using a second iteration Sierpinski carpet fractal shape with circular boundary is presented in this paper. The antenna covers the frequency band from 3 GHz to 12 GHz (VSWR ≤ 2). The proposed antenna has a meander shaped slot that renders the capability to reject 5.15-5.825 GHz band assigned for IEEE802.11a and HIPERLAN/2. The gain is suppressed very well in the desired WLAN bands. The measured antenna peak gain varies from 1.85 dBi to 6 dBi within the band. The time domain characteristics show that the antenna is not dispersive. A fabricated prototype is developed with close agreement between simulated and measured resonance as well as radiation characteristics.

“…Many techniques have already been proposed, such as various shaped slots [2][3][4][5][6], embedded resonant cells [7,8], and half mode substrate integrated waveguide cavity technology [9]. Resonant stubs [10] and parasitic elements [11] are also two effective methods to generate frequency band-notched functions. However, the designs mentioned above either have only one frequency band notch or the notched bands can not be easily tuned.…”

Abstract-An ultra-wideband hexagonal ring antenna with dual tunable band-notches is presented in this paper. The proposed antenna achieves a good impedance match (VSWR ≤ 2) covering the range of 2.5-10.6 GHz, except for the bandwidths of 3.1-3.8 GHz for WiMAX and 5.15-6 GHz for WLAN. The band-notch function is evolved by a stub and two pairs of parasitic elements for WiMAX and WLAN, respectively. The experimental results show that the band-notched characteristics can be tuned by adjusting the lengths of the stub and the two pairs of parasitic elements.
