Table 1. Optimized parameter of modified antenna Parameter Description Value L Length of Antenna 26mm W Width of Antenna 20mm L1 Length of Slot 12mm A Coplanar Waveguide Fed Two Arm Archimedean Spiral Slot ... The antenna is situated in one plane and fed without using an external balun or a matching network. The antenna has wideband input impedance bandwidth with circular polarization (CP), and broad beamwidth radiation pattern over 1.6:1 bandwidth.
To improve the bandwidth, rectangular slits were inserted in the tapered slot antenna, and the antenna area was reduced. The fabricated rectangular slit-inserted tapered slot antenna exhibited a bandwidth of 8.45 GHz and improved its bandwidth by approximately 4.72 GHz. Furthermore, the antenna showed a 15.5 % reduction in area.

Centre for RF and Microwave Engineering, Department of Electronics and Communication EngineeringAn Ultra Wideband (UWB) microstrip diamond slotted patch antenna with enhanced bandwidth is presented. A Multiband Slot Antenna with Enhanced Bandwidth for… To improve the bandwidth and gain of the designed antenna, a triangular parasitic patch is used. After doing a parametric study on the parameters of the designed antenna a triple frequency band is“Bandwidth enhancement of a printed wide-slot antenna with a rotated slot”. IEEE Trans. Printed wide-slot antenna design with bandwidth and… This paper presents a printed wide-slot antenna design and prototyping on available low-cost polymer resin composite material fed by a microstrip line with a rotated square slot for bandwidth enhancement and defected ground structure for gain enhancement. Keywords: Bandwidth Enhancement, Coplanar Waveguide… To improve bandwidth of the designed antenna, two parasitic L-shaped strips are added on right side bottom corner and left upper side top corner in the ground5. CONCLUSION: A parasitic strip loaded slot antenna with coplanar wave guide feeding is designed for wideband communication systems.

The overall dimension of the antenna is 90mm x 90mm. The open slot antenna is fed by a 50- microstrip line of width 3.08mm and length 52mm. A dielectric substrate of r =4.4 and height h=1.6mm is used. To obtain improved bandwidth four rectangular slots in T-shape with one inverted are cut in the ground plane. Multilayered Cavity Material Radial Line Slot Array Antenna ... Multilayered Cavity Material Radial Line Slot Array Antenna with Improved Bandwidth for 5G Communication Application Ibrahim Maina1,2, Tharek Abd Rahman1, Mohsen Khalily1 & Solomon Iliya Zakwoi1 1 Wireless Communication Center (WCC), Faculty of Electrical Engineering, Universiti Teknologi Malaysia, Malaysia Slot Antenna Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). Cavity-Backed Slot Antennas - Antenna Theory A practical slot antenna is the cavity-backed slot antenna. Unfortunately, the equations related to the cavity backed slot antenna are somewhat complicated and in my opinion don't give a good idea of how they work. Hence, I'll present the basics, present some experimental results and try to give an idea of design parameters.
