“…A CPW fed planar antenna having a dimension of 50 × 50 mm 2 has been reported in which electrical ring resonator (ERR) beneath the CPW has been embedded for rejecting WiMAX, WLAN, and 7.5 GHz bands . Two pairs of DGS resonators are used in a CPW fed antenna having a dimension 70 × 80 mm 2 , to reject 2.5/3.5 GHz WiMAX, 802.11a WLAN, ITU‐8 band . But both these antennas have the limitation of large size.…”

A coplanar waveguide (CPW) fed printed compact monopole antenna with five band rejection features is presented. Wide bandwidth was achieved by beveling the lower part and adding a modified ellipse on the upper portion of the patch. An inverted circular arc, single circular split ring resonator (SRR) with wide opening and two symmetrical circular single SRRs were embedded for obtaining three stop‐band characteristics. Two symmetrical slits were inculcated in the ground forming defected ground structure (DGS) to get another stop‐band characteristic. Two concentric rectangular modified SRRs were etched to obtain a higher frequency stop‐band feature. The proposed antenna was designed, fabricated, and experimentally tested for the validation of results. The overall dimensions of the proposed antenna were 29 mm ×24 mm × 1.6 mm. The measured impedance bandwidth of the antenna was 2.87 to 13.3 GHz at | S11|< − 10 dB. The measured results show that the proposed antenna has five band notches centred at 3.96, 4.35, 5.7, 8.54, and 9.95 GHz to reject WiMAX band (3.65‐4.04 GHz), ARN band (4.29‐5.18 GHz), WLAN band (5.5‐6.9GHz), ITU‐8 band (7.37‐8.87), and amateur radio band (9.2‐10.3 GHz) respectively. The proposed antenna maintains omnidirectional radiation pattern in H‐Plane and dumbbell‐shape radiation pattern in E‐plane. Further, stable gain over the whole UWB except at notched frequency bands was reported.

“…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.…”

“…In Reference , the triple‐band rejected function is realized by etching elliptic slot in the patch. In Reference , the multiple‐band notched performance is obtained by employing Defected Ground Structure (DGS) slot in the ground. The band‐notched characteristic can also be obtained through introducing band‐notched structure on the feed‐line .…”

A miniaturized ultra‐wideband (UWB) monopole antenna with reconfigurable multiple‐band notched performance is demonstrated. By modifying the shape of the patch and the ground plane, the UWB operation is achieved. The first and second band‐notches are respectively generated by etching a rectangular slot with open ends and a U‐shaped slot in the patch, and the third band‐notch is produced by loading a C‐shaped parasitic element beneath the patch. To realize the reconfigurable band‐notched functions, four PIN diodes are inserted in three band‐rejected structures. The antenna has a compact dimension of 30 mm × 26 mm. It can switch between a UWB state and several band‐notch states by alternating the states of the diodes. Also, good radiation patterns are obtained.

“…In Reference , half wavelength stubs and slits on the patch were employed to create passband notch which demonstrated reduced cross‐polarization. Generating defected ground structure (DGS) produced a notch in References , but the DGS led to wave leakage which affected the radiation properties at higher frequencies. The filtenna in Reference exhibits fair bandwidth and selectivity but radiation response is poor.…”

This manuscript proposes a triple band filtering antenna operating in the frequency range of 2.4 to 2.484 GHz, 4.2 to 4.5 GHz, and 5.15 to 5.825 GHz for possible application in WLAN and aeronautical radio navigation. Initially, a conventional square shaped monopole antenna is designed at 4 GHz, in which staircases are introduced at the edges to enhance bandwidth. Later, a triangle shape is carved out of square patch and cascaded at the junction to generate the proposed sunflower shaped fractal filtenna. Also, the ground plane is modified to further enlarge the bandwidth. By inserting C shaped complimentary split ring resonator slot on the feed line, a stop band is created at 3.5 GHz. Within the proposed frequency band of operation, the filtenna depicts omni‐directional radiation pattern, good selectivity, and low insertion loss. Also, the VSWR observed is less than 2 and peak antenna gain is 3.5 dBi. A good uniformity is achieved between the simulation and the experimental.
