“…For WLAN (Wireless Local Area Network) 5.5 GHz band rejection for high data rate applications, various techniques have been employed to attenuate or reject the signals with specific bands [15]. The recommended antenna is contrasted with alternative antenna designs in the 02029-2 comparison Table [2,[16][17][18][19][20]. This work is on the development of a compact structure antenna with high gain and a large bandwidth with single-notch characteristics by Inserting a quadruplet arrow slotted structure on a circular patch antenna with a slotted ground results in the desired notch band.…”

In this work, a compact quadruplet arrow slotted elliptical shaped notch band printed microstrip antenna is designed and analyzed for modern wireless communication systems. Initially, a compact elliptical-shaped antenna model with defected ground structure is designed for ultra-wideband (UWB), having a working range of 3.1 to 10.6 GHz. The design was modified with a quadruplet arrow slot which resulted in single-notch band characteristics for wireless LAN bands. The realized peak gain of the recommended antenna is 5.11dBi at a frequency of 3.7 GHz. The analysis of the suggested antenna has been performed by evaluating different geometrical shapes. The surface current distribution analysis is also presented to provide a clear insight on the working principle of the antenna. The various characteristics parameters such as return loss, gain, radiation patterns are presented and discussed. The suggested antenna model occupying a total dimension of 26  24  1.6 mm 3 in size is simulated and its results are investigated with CST tool. The designed antenna is prototyped over FR4 substrate for measurement validation. The simulation results of the prescribed antenna are matched with experimental data for validation. The findings indicate that the suggested compact antenna is well-suited for high-speed, close-range communication and can effectively reject signals from the WLAN band.

“…These researchers have used filters or band notch characteristics to remove the unwanted frequency bands. To eliminate the interference from UWB range, the antennas with different band notch characteristics have been proposed including different types of slots such as L-shaped slot [6], U-shaped slot [7,8], V-shaped slot [9] on the ground plane or on the radiating patch, stubs, parasitic elements, split ring resonator (SRR), complementary split ring resonator (CSRR), and etching on patch or ground plane [10]. The researchers have carried out extensive research on UWB band notched antennas using different techniques.…”

Compact CPW-fed ultra-wideband monopole antennas with band notch characteristics using Split Ring Slots (SRSs) are proposed in this manuscript. Initially, the antenna is designed by using a rectangular shaped patch, and it has been modified to obtain enhanced impedance bandwidth (VSWR ≤ 2) throughout the entire UWB frequency range. Further, the notch band element (split ring slot) has been introduced in the geometry of proposed antenna to generate the band rejection at WLAN frequency centered at 5.3 GHz (5.15-5.81 GHz). Another antenna has been designed by varying the dimensions of SRS to get the rejection of frequency at an X-band satellite communication system centered at 7.4 GHz (7.16-7.71 GHz). The overall size of proposed UWB antennas is compact (18 × 18 mm 2 ), and it is designed on a low cost FR4 glass epoxy substrate with 1.6 mm thickness and 4.4 dielectric constant. The proposed antennas with and without a notch filter are designed by using HFSS V13 simulator and fabricated for the validation of simulated results. Experimental and simulated results are compared and found in reasonable agreement with each other.

“…To avoid the interference associated with narrow band systems like wireless local area network (WLAN), WiMAX, Wi-Fi etc, notching is very much needed. Different notch band techniques are proposed by the researchers in the literature for UWB antennas [1,2,3,4]. To transmit the power efficiently, the channel will play a significant role.…”

A triple band notch multiple-input-multiple-output (MIMO) antenna is designed and proposed with complementary-split-ring-resonators (CSRR) on upper side and defected ground structure on bottom portion of the FR4 substrate material. A square shaped radiating element with cone shaped microstrip line feeding is used in the current design to achieve 50-ohm impedance. A compact dimension of 36 Â 22 Â 1.6 mm is used to fit this model for portable communication devices. Split ring resonators are placed adjacent to the feed line to improve the gain and defected ground with stubs is placed to enhance the bandwidth characteristics. Proposed antenna has bandwidth ranging from 2 to18 GHz with notching at 5.2-5.8 GHz (WLAN), 11-12 GHz (Satellite Broadcasting) and 12.5-14.5 GHz (Aeronautical Radio Navigation). The envelope correlation coefficient (ECC) is less than 0.005 and mutual coupling is less than 15dB achieved. The prototyped antenna is providing peak realized gain of 5dB and maximum efficiency of 75% in the operating band. The results strongly support the applicability of current antenna model with band notching in wideband communications.
