Novel dual band‐notched UWB antenna with T‐shaped slot and CSRR structure

Abstract

A dual band‐notched ultrawideband antenna is proposed in this article. The antenna consists of a U‐shaped radiation patch and a ground plane which is symmetric with the edge of the radiation patch. By attaching two T‐shaped slots on the radiation patch and two rectangular complementary split‐ring resonators on both sides of the microstrip line, two notched bands, 3.3–3.7 GHz for WiMAX and 5.15–5.825 GHz for WLAN are achieved, respectively. The dimension of the proposed antenna is 24.6 mm × 38.1 mm × 1.5 mm. The measured result shows that the antenna has a wide impedance bandwidth and omnidirectional radiation patterns. Moreover, time‐domain characteristics and conceptual circuit model based on the input impedance of the proposed antenna are investigated to verify the dual band‐notched characteristics. © 2015 Wiley Periodicals, Inc.

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.…”

A compact CPW‐fed UWB antenna with quadruple rejected bands

“…Secondly, band‐notched functions can be obtained by utilizing tuning stubs on the patch or ground plane . At last, parasitic patches and stubs are employed to the UWB designs, which could also realize the band‐notched characteristics . For the aforementioned antennas, single or multiple rejected bands can be achieved.…”

Hexagonal Printed Monopole Antenna with Triple Stop Bands for UWB Application

“…The dual stop band circular design with size of 35.5x30x1.6mm is propounded, the antenna is printed on FR4 substrate [6]. The U shaped antenna with dual notched band is proposed, the bands is stopped with CSRR (Complementary Split Ring Resonator) and T shaped slot and the size of antenna is 24.6x38.1 mm 2 [7]. The triple notched band antenna with dimension of 24x34.6 mm is designed, the height of substrate is .8mm [8].…”
