A Triple Band Notch Compact UWB Printed Monopole Antenna

Experimental Investigation of a Planar Antenna with Band Rejection Features for Ultra-Wide Band (UWB) Wireless Networks

“…The antennas presented in [12][13][14][15][16][17] are relatively larger in size and offers band-notching in a single frequency band. UWB antennas of comparable size have been proposed in [18][19][20][21][22][23][24][25]; however these designs give band-notching in two frequency bands. The UWB antennas covered in [26][27][28][29][30][31] use relatively complex mechanisms to attain band rejection in triple frequency bands.…”

“…The band-notched characteristics in UWB antennas are obtained by using various techniques such as slots in the feed line, ground, or radiator [10,11]. Till now researchers have applied various techniques to obtain single [12][13][14][15][16][17], dual [18][19][20][21][22][23][24][25], and triple [26][27][28] band-notching of narrowband channels operating within the UWB spectrum. In [12] a 50 × 42 mm 2 UWB antenna has been designed to suppress or notch the WiMAX frequency band (3.3-3.8 GHz) by using electromagnetic bandgap structures.…”

“…The pin diodes need additional resources (lines and dc-supply) to operate it in the reverse/forward bias mode. The WLAN and WiMAX frequency bands have been notched by using the techniques mentioned in [18][19][20][21][22][23][24]. In [18] the authors have designed a 38.…”

“…Similarly, resonators [20] in the top layer are used for WLAN and WiMAX band rejection. Likewise, U-shaped [21], rectangular-shaped [22], H-shaped [23], and circular shaped [24] slots have been etched within the radiating element, to slash the aforementioned bands. In [25] different types of resonators have been printed on the ground plane to reject the ITU (7.8-8.4 GHz) and WLAN (5-5.4 GHz) frequency bands.…”

Design of CPW-Fed High Rejection Triple Band-Notch Uwb Antenna on Silicon Substrate With Diverse Wireless Applications

“…Triple notched band resonators in a single design are fabricated [11] by inserting a C-shape slot at main radiator, complimentary SRR (CSRR) at ground plane and an inverted U-shape slot at the center of the patch, resulting in narrow band rejection of triple-notched band. Two bevels along with two round-shape slots in a rectangular patch and a pair of C-shaped slots in the ground plane re responsible for a triple-notched band UWB antenna [12]. A spiral slot on the rectangular CPW fed monopole antenna is presented [13], and by varying the length of the single spiral slot, triple notches with central frequencies of 3.57 GHz, 5.12 GHz and 8.21 GHz, respectively, are reported.…”
