Abstract-In this paper, a modified square slot antenna with modified radiating patch, for UWB applications is proposed. The proposed antenna consists of a square radiating patch with a double fed structure and a ground plane with a pair of L-shaped slots which provides a wide usable fractional bandwidth of more than 140% (3-18 GHz). By optimizing the L-shaped slots dimensions and rectangular slot width, the total bandwidth of the antenna is greatly improved. The designed antenna has a small size of 35 × 35 mm 2 .

“…The substrate used is FR4 with permittivity 4.4, thickness 1.6 mm, loss tangent 0.0018 and has a size of 14 mm × 20 mm. The width of the microstrip feed line W f is fixed at 2 mm [2]. The radiating monopole and feeding mechanism are printed on the top side of the substrate, while the ground plane is printed on the bottom side of the substrate.…”

“…This truncated ground plane acts as an impedance matching element to control the impedance bandwidth of the monopole. This phenomenon occurs because the truncation creates a capacitive load that neutralizes the inductive nature of the patch to produce nearly-pure resistive input impedance [2,3].…”

Abstract:A novel modified printed monopole antenna with variable frequency band-notch characteristic for ultra-wideband (UWB) applications is presented. The proposed antenna consists of a truncated ground plane and a radiating patch with two tapered steps. To generate a notch band at 5-6 GHz with good level of band-notch a new T-shaped parasitic element placed on the back layer of the substrate along with a simple circular slot etched on the patch is implemented. The proposed antenna has a compact size of 14 × 20 mm 2 , a measured impedance bandwidth of 3.05 to 14.7 GHz for VSWR < 2 and exhibits an omni-directional H-plane radiation pattern throughout the UWB frequency range.

Abstract-In this paper, a novel double-printed trapezoidal patch dipole antenna suitable for UWB applications with band-notched characteristic is presented and investigated.The band-notched characteristic is achieved by inserting T-shape slots on the trapezoidal radiating patches. The impedance characteristic, radiation patterns and the transfer function are studied. Experimental results show that the proposed antenna covers the entire UWB band (3.1-10.6 GHz) while it has a notched band for the IEEE 802.11a frequency band (5.15-5.825 GHz). Measured group delay, transmission characteristics and Time domain characteristics indicate that the proposed antenna satisfies the requirement of the current wireless communications systems.
