If higher gain is desired, the antenna must necessarily be a narrow-band device. In fact, the input impedance becomes frequency sensitive so rapidly that, for large antennas, no significant increase in gain over that of the uniformly illuminated aperture is possible. Also, if the antenna … Impedance Bandwidth and Gain Improvement for … The configuration of the initial antenna with dimensions of 28 × 32 mm2 is shown in [14]. The bandwidth of that antenna is from 5.3 to 8.5 GHz for |S11| < -10 dB and the gain is generally above 4 dB with the peak of 7.2 dB. In the work reported this paper, three improvements were made. Enhanced-Gain Planar Substrate-Integrated Waveguide Cavity High-gain antennas have various applications such as in satellite platforms, radar systems, routers, and repeater systems. A number of enhancement techniques for antenna gain have been studied –.To realize enhanced-gain performance, a cavity-backed slot antenna (CBSA) is employed in this study because of its unidirectional characteristic. Printed Wide-Slot Antenna Design with Bandwidth and Gain To increase the gain, four L-shaped slots are etched in the ground plane. The measured results show that the proposed structure retains a wide impedance bandwidth of 88.07%, which is 20% better than the reference antenna. The average gain is also increased, which is about 4.17 dBi with a stable radiation pattern in the entire operating band.

Henceforth, this paper presents a high gain coplanar waveguide (CPW)–fed slot antenna for CubeSats. A key feature is the use of a metasurface superstrate structure (MSS) to significantly improve gain and reduce back-lobe emissions. This also has the advantage of minimizing interference to components inside a CubeSat. Bandwidth And Gain Improvement Of Microstrip Slot ... In this paper a printed micro strip line fed wide slot antenna is presented. A slotted parasitic patch is introduced to improve the gain along with the bandwidth. For bandwidth improvement a slotted technique is used in ground of the antenna along with rotation in patch and a simple 50 ? microstrip line fed is used to excite the slot in the ...
