In this article, a novel design of a planar antenna with modified patch and defective ground plane for UWB applications is presented. The optimum dimension of the antenna is 20 × 25 × 1.5 mm3 and it is fabricated on commercially available low‐cost FR‐4 substrate having relative permittivity (εr = 4.3) and relative permeability (μr = 1) with a loss tangent of 0.025. The impedance bandwidth of the proposed antenna (magnitude of S11 [S11 < −10 dB]) is 110% (3.1‐10.8 GHz). The peak gain and the peak radiation efficiency of the proposed antenna is 5.1 dB and 89%, respectively, in the proposed band of operation. Simulated and measured results of the proposed antenna are in good agreement. The proposed antenna is suitable for ultra‐wideband applications, 3.5/5.5 GHz WiMAX band, 5.2/5.8 GHz WLAN band, 4/6 GHz satellite communication, and various other wireless communication applications.

In this article, a compact UWB planar antenna with corrugated ladder ground plane is presented. The antenna has a compact size of 15 × 20 × 1.5 mm3. The proposed antenna is fabricated on low cost, easily available FR‐4 substrate with relative permittivity εr = 4.3, permeability μ = 1, and loss tangent of 0.025. The thickness of the FR‐4 substrate is 1.5 mm. The impedance bandwidth of the proposed antenna (magnitude of S11 <−10 dB) is 130.4% (2.4‐11.4 GHz). The peak gain of the proposed antenna is 3.5 dB and the peak radiation efficiency of the proposed antenna is 76%. Stable omnidirectional radiation patterns (H‐plane) and bidirectional radiation patterns (E‐plane) are observed in the entire operating frequency range. One side of the antenna with corrugated ladder ground plane results in the reduction of operating frequency of the proposed antenna and it reaches till 2.4 GHz whereas the other side of the antenna consist of the circular patch with a circular slot which results to resonant the proposed antenna in the higher operating band. With these properties, the proposed planar antenna is suitable for 2.4 (Wi‐Fi), 2.5/3.5/5.5 GHz (WiMAX) bands, 2.5/5.2/5.8 GHz (WLAN) bands, and other UWB wireless communication applications.

“…A fork‐shaped radiating patch in Reference , differentially fed partially cut elliptical patches in Reference , elliptical patch with circularly symmetric slot in References 3 and 4, open‐ended T‐shaped slot with feed line extension in Reference , double L‐slot patch in Reference , lobster‐shaped ground plane with multiple slots have been reported recently. The partial ground plane and slots impact the overall bandwidth of the antenna and its return loss characteristics. These effects have been analyzed for the proposed design.…”

In this article, a compact broadband planar monopole microstrip patch antenna with extended patch and a truncated ground plane is proposed for ultra‐wideband application. The optimal dimensions of the proposed antenna are 20 × 20 × 1.6 mm3. The proposed antenna is fabricated on FR4 substrate that is a low‐cost commercially available substrate with εr = 4.3 and a loss tangent of 0.025. The impedance bandwidth (defined by the magnitude of S11 less than −10 dB) of the proposed antenna is 127% (3.13‐14.07 GHz). The peak gain and radiation efficiency of the proposed antenna are 3.4 dB and 78%, respectively. The proposed antenna exhibits a stable radiation pattern at the operating band. The simulated results of the proposed antenna are observed to be in agreement with the measured results when fabricated. The proposed antenna supports various frequency bands such as ultra‐wideband, 3.5/5.5 GHz WiMAX bands, 5.2/5.8 GHz WLAN bands, X Band (8‐12 GHz), satellite communication, and other wireless communication services. The proposed design and its various results have been discussed in further detail.
