“…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]. Introduction of open-end slit to the antenna structure and addition of a tuning stub within the antenna structure or the ground plane were also reported to create and control notched band/s [34][35][36][37][38][39].…”

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 knowledge of a material's dielectric property is necessary in determining its suitability for a specific application. FR4 material is widely being used as a substrate on most of the antenna design and the dielectric properties of the material dielectric constant is alias between 4.3 to 4.9 [6]. The usage of FR4 board suffer on strength and temperature on certain application due to the fabrication process itself while the new proposed leucaena leucocephala WPC board offer some immunity to the greater on strength and temperature to about 180 0 C of melting point and this will be great on certain application especially on high power application later.…”

The fabrication of single patch antenna for proposed Leucaena Leucocephala (""Petai Belalang"") Wood Plastic Composite (WPC) substrate board and FR4 substrate board is presented in this paper. The experiment objective was to measure the performance of an antenna fabricated on the proposed board by comparing the performance in term of Dielectric Constant value, Tangent Loss value, Return Loss, Radiation Pattern and Gain with antenna fabricated onto FR4 material substrate board. The idea is to find the potential alternative board replacing conventional printed circuit board (PCB) using commercial FR4 material. The dielectric constant and tangent loss value for both proposed and FR4 substrate board were analyzed with Agilent 85070E Dielectric Probe Kit method. The Fabricated proposed boards were studied in the frequency range of 2.2 to 3.3 GHz since this board will be used in ISM band application that occupied 2.45 GHz frequency spectrum. The parameter composition of proposed board on this paper was focused only on one density composition that is 70% of polypropylene and 30% of leucaena leucocephala filler wood with particle size maintained at 150 µM and moisture content of the filler is less than 5%. The indoor Practical Antenna Measurement method was used to prove the proposed antenna can be used as transmitting antenna and all result obtained were form as data and graph analysis.

“…There are even configurable UWB antennas with band notches which can be actively switched on or off by using a MEMS or a PIN diode, or tuned by means of a varactor [23][24][25]. Furthermore, both switchable and tunable characteristics can be achieved in the same UWB antenna by using a PIN and a varactor together [26]. However, most of these antennas have only one notch band around WLAN band.…”

Abstract-An ultra-wideband (UWB) printed monopole antenna with dual band-notched characteristics is proposed. Two spiral electromagnetic-bandgap (EBG) structures placed on the front and back side of the substrate are employed to create two notch bands at 5.2 and 5.8 GHz for the lower and upper bands of the wireless local-area network (WLAN), respectively. The notch-frequency can be tuned, and the band width is narrow and adjustable. Furthermore, the spiral EBG structure used in this design are more compact than conventional mushroom-type EBG. Equivalent circuit model is extracted and discussed to explain the operating mechanism of this structure. The proposed antenna has been simulated and measured in both the frequency domain and time domain, good agreement between calculated and experimental results has been achieved.
