“…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 current distribution at notch frequencies are shown in Figures 6(b)-(d) and these show very strong current distribution concentrated around slot S 1 , S 2 and S 3 at a center frequency of notch band 3.5 GHz, 5.5 GHz and 7.5 GHz, respectively. The strong current distributions around slots at the notch frequency leads to near field radiation counteracted, due to which high energy is reflected back to the input port and the band-notched characteristics achieved [18]. It also can be noticed that in Figures 6(b)-(d) there are very low mutual coupling at the notch frequencies, which indicate that each rejected band can be controlled independently.…”

Abstract-In this article, a compact ultra-wideband (UWB) planar monopole antenna with the triple notched band is proposed. The antenna consists of a semicircular radiating patch and a modified ground plane with two bevels at upper edge. By etching two round shape slots in radiating patch the notch characteristics are achieved at WiMax band (3.3-3.7 GHz) and WLAN band (5.15-5.875 GHz). In order to realize notch band at X-band downlink satellite communication band (7.1-7.76 GHz) a pair of rotated V-shape slot are etched on the ground plane. The measured operating impedance bandwidth of proposed antenna ranges from 2.9 to 10.9 GHz having return loss less than 10 dB with triple notched bands. The proposed antenna exhibits a nearly omnidirectional radiation pattern in the H-plane, and a dipole-like radiation pattern in the E-plane for the ultra-wideband. The effects of each individual slot on band-notch characteristics are also investigated. The measured gain of the proposed triple band notched antenna is relatively stable across the operating frequency band except notched bands and thereby making the proposed antenna suitable for practical UWB applications. Proposed antenna has a compact size of 27 × 25 mm 2 .
