Design and analysis of a coplanar waveguide fed ultrawideband hexagonal open slot antenna with WLAN and WiMAX band rejection

Abstract: A simple coplanar waveguide fed hexagonal like open slot antenna has been considered for ultrawide bandwidth (UWB) in this article. This antenna is then modified to obtain dual band rejection. Dual band rejection frequencies (WLAN: 5.0–5.9 GHz, WiMAX: 3.3–3.7 GHz) at 5.5 and 3.5 GHz are achieved by embedding a U‐shape slot in the exciting stub as well as a couple of L‐shape open circuit stubs at the edge of the slot, respectively. The length and width of the U‐shape slot and L‐shape stubs offer sufficient free… Show more

“…To reduce the interference between the UWB and narrowband systems, one of the promising solutions is using band‐rejected UWB antennas. Usually, the notched band is generated through cutting slots in the patch or the ground plane . In Reference , the triple‐band rejected function is realized by etching elliptic slot in the patch.…”

“…Moreover, wideband antennas are typically designed based on the conventional monopole and Vivaldi topologies. These antenna types either apply a partial rear ground plane or integrate their ground planes on the same plane as the radiating elements, as is widely used in the coplanar waveguide (CPW) structures . However, the unavailability of full ground plane on their reverse side or back reflectors typically causes the antenna to radiate bidirectionally, usually in the forward and backward directions.…”

“…Then, stable realized gain with good band-notched characteristics and omnidirectional radiation patterns is desired. Therefore, various simple shapes like rectangular, circular, elliptical UWB and slot antennas with and without single/dual band-notched functions are reported and demonstrated in the literature [3]- [16].The planar circular and elliptical UWB antenna [3]- [5], circular and elliptical slot UWB antenna [6]- [7], band-notched circular slot UWB antenna using inverted C-shaped parasitic stub [8], heartshaped UWB antenna using U-shaped slot for band-notched UWB applications [9], band-notched semi-elliptic slot UWB antenna [10], dual band-notched UWB antenna [11], dual band-notched UWB antenna using defected ground structure (DGS) and split-ring resonator (SRR) [12], dual bandnotched compact UWB antenna [13], a CPW-fed dual bandnotched hexagonal open slot antenna [14], dual bandnotched UWB antenna using complementary SRR [15], and electromagnetically coupled elliptical UWB antenna using parasitic element [16] are reported and presented.…”
