“…Three round ground grooves are used in [11] to get percentage bandwidth of (2.87 -50) GHz (178.29%). One round cut in each corner of the patch antenna and one ground groove are used in [12] to get a bandwidth of (3.42 -11.7) GHz (109.52%). Making triangular shape slots on the top of the partial ground plane in [13] increases the UWB antenna bandwidth to (2.95 -15.45) GHz 135.87%.…”

“…[8][9][10] In the recent time, UWB behavior has been also reported by several different geometries, such as round cutting in the rectangular patch, circular patch with a tapered microstrip line, cutting a rectangular slot in the ground along with circular ring radiator, circular ring in the patch. [15][16][17][18] elliptical, tulip, circular shape for the patch has also suggested UWB behavior. [19][20][21][22][23][24] Majority of the designs proposed in the above literature are comparatively larger, a comparison between the above recently published monopole antennas (size with a magnitude of S11) is shown in Table 1.…”

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.

“…Cutting stair‐shaped elements in the ground plane results in broadband characteristics due to excitation of lower order resonances . Due to round cutting in rectangular patch and one slot in the ground plane, UWB applications have been reported with a good signal strength . The compact structure for the UWB satisfies stable radiation pattern and impedance matching throughout the operating frequency .…”

A compact ultrawideband planar antenna with modified circular patch and a defective ground plane for multiple applications is presented. The proposed structure consists of a modified circular patch and rectangular parasitic elements with defective ground plane etched on flame retardant (FR‐4) substrate with 50 Ω feed line. Return loss (S11 < −10 dB) and the simulated bandwidth of the structure was 2.5 to 12.2 GHz with the fractional bandwidth of 131%. The overall volume of the structure had a compact size of 15 × 19 × 1.6 mm3. The gain of the structure is 3.5 dB, and the antenna efficiency is 73.5%. The structure radiated (stable radiations) omnidirectional and bidirectional patterns. Measured and simulated results of Co‐ and Cross‐polarizations. are in relatively good agreement. All these properties shows that the proposed structure is applicable in WiMAX‐band 3.5, 5.5 GHz, WLAN‐band 5.2, 5.8 GHz, X‐band8‐12 GHz, data links to satellites along with various applications in the wireless communication field.
