A parasitic fed ultra‐wideband antenna is proposed for WLAN and UWB applications. The proposed antenna consists of parasitic hexagonal patch surrounded by hexagonal slot and ground plane in same side of the substrate. Microstrip line present on the other side of the substrate excites the patch parasitically. The overall size of an antenna is 25 × 25 × 1.6 mm3. The prototype antenna is designed, fabricated and tested. It provides good return loss characteristics and radiation pattern. The measured −10 dB impedance bandwidth are 2.12 GHz (3.71 GHz to 5.83 GHz) and 6.1 GHz (6.05 GHz to 12.15 GHz) with resonance frequencies at 5.25 GHz and 6.73 GHz respectively. Since, this antenna provides good resonance at 5.25 GHz having impedance bandwidth more than 1 GHz, this can be used for WLAN applications. This antenna also provides notch band from 5.83 GHz to 6.05 GHz where vehicular ad hoc network (VANET) devices operate. Hence, this antenna does not cause interference to VANET devices. Parametric studies on patch, slot dimension, feed length are done to validate the results. The simulated and measured results of the antenna are in close agreement with each another. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2996–3000, 2016

“…Creating a wide slot on the ground is another method to enhance impedance bandwidth of the antenna. Recently, many wide slot antennas have been reported for broadband applications such as rectangular slot [7,8], triangular slot [9], rotated slot [10] and pentagonal slot [11]. The addition of tuning element with a proper dimension and location is another approach to improve the performance of a wide slot antenna.…”

Abstract-A wide slot antenna with Y shape tuning element is presented for wireless applications (GSM 1800, WiMAX, PCS and ITM-2000). The proposed antenna is fabricated on an FR-4 substrate (tan(δ) = 0.02, ε r = 4.3) with the thickness of 1.6 mm. On the top layer of the substrate, a 50 ohm microstrip line is fabricated which is terminated in Y shape tuning element. On ground plane, an irregular wide slot and triangular notch are etched. In addition, for performance improvement two triangular shaped parasitic slots are embedded on the ground plane. The proposed antenna is energized by the microstrip line. It exhibited the bandwidth of 127.55% from 1.15 GHz to 5.2 GHz for |S 11 | < −10 dB. Surface current distribution and radiation pattern at resonating frequencies 1.25, 1.9 and 4.2 GHz are analyzed. Impact of parameters on S 11 characteristic is also studied to know the behavior of the antenna.

“…The vertical rectangular open ended slot in radiating surface of proposed monopole antenna can be a substitute for two semicircular slots [18] to achieve band-notch characteristics in X-band. Recently reported compact planar antennas for multiband operation are also studied [19], [20]. Figure 1 shows the geometry and photograph of proposed pentagon shaped band-notched multi-wideband monopole antenna.…”

A coplanar waveguide feed pentagonal shape band-notched monopole antenna is proposed for multi-wideband operation. To avoid the potential interference of existing narrow bands with ultrawideband, the open ended slots embedded in monopole radiating surface and thin ground plane are used as notch filter centered at 3.5 GHz and 7.5 GHz respectively. The open circuit semi-spirally extended thin ground plane is designed for rejection of the band centered at 5.2 GHz. The Bandwidth is enhanced by suppressing the spurious notch band. The four operating bands developed due to the insertion of three notch bands, have -10 dB impedance bandwidth of 594 MHz (2.714-3.308 GHz), 990 MHz (3.952-4.942 GHz), 1.12 GHz (5.964-7.088 GHz) and 3.1 GHz (8.25-11.35 GHz) respectively. Group delay less than 1ns across all operating bands show good signal integrity. The radiation patterns in the H-plane are omnidirectional with low cross polarization levels and bidirectional in the E-plane. The simulated and measured results are in good agreement.
