“…Selectivity of filtenna can be improved by placement of transmission zeroes (TZs) at desired frequency point [2]. Now-a-days, filtennas has gained the popularity for numerous applications, namely military application, cognitive radio wireless system, UAV radar, multi-band operation, and WLAN applications [3].…”

This manuscript presents a compact dual-band monopole antenna for WLAN/WiFi. The proposed antenna is comprised of a wideband monopole antenna integrated with a wideband bandstop filter (BSF). Within the proposed frequency band of operation, the proposed antenna exhibits good selectivity and low reflection loss. The measured results show that the proposed antenna can provide two separate impedance bandwidths; 290 MHz (about 12% centered at 2.4 GHz) and 500 MHz (about 9% centered at 5.5 GHz), making it suitable for WLAN operation in the 2.26-to-2.55GHz band and 5.3-to-5.8GHz. The observed VSWR is less than 2.2 and the peak antenna gain is 1.5 dBi within the frequency range. Performance analysis of the ultrawideband monopole antenna, BSF and their integrated counterpart has been carried out methodically in this paper. A consistency has been found between simulated and experimental results. Furthermore, the size of the proposed antenna is 35 x 27 x 1.6 mm3, which is quite compact and suitable for the WLAN/WiFi application.

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.

“…The antenna with filtering function is known as filtering-antenna or filtenna. Filtering-antenna has several advantages such as miniaturize the size, simplify the design, reduce the losses and multifunction operation [10]. Thus, there is a growing interest to integrate resonant structures in the antenna design to produce stopband characteristics using different techniques.…”

An ultra-wideband (UWB) filtering-antenna with controllable band notch is reported in this paper. The filtering-antenna consists of a modified monopole antenna and defected microstrip structure (DMS). The monopole antenna is modified using microstrip transition in the feedline and block with a triangular-shape slot on each side of the circular patch to produce wider impedance bandwidth with better return loss. The DMS is constructed using U-shaped slot etched on the feedline to provide band notch and remove WLAN band (5.1-5.8 GHz). A switch is employed in the DMS to control the created band notch. The measured results show that the proposed design exhibits a wide impedance bandwidth with controllable WLAN band rejection, realized peak gain of 4.85 dB and omnidirectional radiation pattern. Therefore, the proposed design is suitable for UWB applications.
