This article presents a compact dual band antenna for WLAN/IEEE-802.11n applications with frequency reconfigurability nature. The resonant modes are achieved through slots incorporated in the radiating structure and tunability in the band is achieved by PIN diodes switching. The proposed monopole slot antenna with dimensions of 55 X 52 X 1.6 mm placed on Rogers RT-duroid substrate of permittivity 2.2 and loss tangent 0.0009. The changes in first and second resonant frequencies are attained with switching of diodes connected between slot gaps. The switching properties of the diodes are utilized in optimum way to notch certain frequencies and to choose operation frequencies. Low cross polarization with stable radiation pattern and average gain of 2.8 dB are the key elements for this novel antenna. The designed antenna is showing good impedance bandwidth of 68% and peak realized gain of 4.86 dB at 5.6 GHz WLAN band. A good matching between measured results and simulation studies are obtained from the current antenna design.

“…Several antenna design methods have been proposed to produce the band‐rejection in the UWB band. Among other approaches, providing UWB antennas with band‐notched characteristic is necessary to solve this emerging problem of narrowband interference . In this article, we propose a printed microstrip U‐shaped UWB antenna with dual band‐notched configured for the bands of 3.375–3.945 GHz (WiMAX) and 5.425–6.150 GHz (HYPERLAN/2 and WLAN).…”

In this article, we present a compact ultrawideband antenna with dual broadband‐notched characteristics centered at 3.4 and 5.5 GHz. The proposed antenna consists of a rectangular patch with a modified ground plane structure and 50 Ω microstrip‐fed line. By etching two opposite U‐shaped slots in the radiating patch, the notched bands of 3.375–3.945 GHz for WiMAX and 5.425–6.150 GHz for WLAN and HYPERLAN/2 were achieved. The antenna also offers a flat frequency response so minimizing the formation of spurs and precursors that ensures optimal time domain performance for ultrawideband radio applications. The return loss was measured to better than −10 dB over the entire band from 3.1 to 10.6 GHz. The antenna gain was larger than 2 dBi all over the frequencies with a flatness of 2.5 dB and an omnidirectional radiation pattern in the H‐plane. © 2015 Wiley Periodicals, Inc.

“…However, within this band, the 5.15-5.825 GHz frequency band is used by IEEE 802.11a wireless LAN (5.5-GHz WLAN) system and, thus, any electromagnetic interference caused from the use of 5.5-GHz WLAN system should be avoided to ensure the UWB transmitter performance. So far, several UWB antennas with the rejected band of 5.15-5.825 GHz have been reported, which applied different techniques including use of the parasitic element [1], shaped slotted-patch [2][3][4][5][6], resonator element [7,8], defected ground structure [9][10][11], and distorted patch or strip [12][13][14][15]. However, most of them are not only with a complex or larger structure but also with a difficult fabrication process resulting from achieving the band-rejection function by inserting slot or additional control element into the antenna.…”

To suppress electromagnetic interference at 5.5-GHz WLAN (5.15-5.825 GHz) band operation, a novel ultra-wideband (UWB) design of a slotted twin-patch monopole antenna with a band-rejection characteristic is presented. The proposed antenna with a simple structure has a large impedance bandwidth, defined by 10-dB return loss, covering the range from 2.95 to 10.85 GHz, and a tunable cutoff band from 5.18 to 6 GHz for band-operation suppression. Measured monopole-like radiation pattern and in-band average gain of about 2.3 dBi have also been obtained, simultaneously, with good agreement to the simulated results.
