How to increase antenna gain - Quora Oct 24, 2017 · Answer Wiki. You cannot increase gain in all directions. Highly directional antennas provide high gain in one direction with highly attenuating signals in other directions. It is an axiom of engineering — you never get something for nothing. The good news is that attenuating in some directions while increasing it in others is other just what you want. Printed Wide-Slot Antenna Design with Bandwidth and Gain Feb 13, 2014 · 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.

www.w1ghz.org case when each of the elements is a long slot antenna. For example, two long slot antennas each 2.1 wavelength long with an overall aperture of 4.2 wavelengths has a gain of about 7.35. An array consisting of four long slot elements, each two wavelengths long has a gain of 16.4. The aperture-gain

Printed Wide-Slot Antenna Design with Bandwidth and Gain ...

Gain Enhancement & Comparison of Rectangular Slot Patch ... Abstract: In this paper, Circular Microstrip Patch Antenna and Rectangular Slot Patch Antenna comparison of present and an effort is made to optimize the gain to show better performance analysis on the basis of design and simulation results by implementing FSS structured superstrate layer at operating frequency of 5.8 GHz for ISM Band. The skeleton slot was developed in the UK for TV use soon ... increase in gain for the extra material and effort on 2m, but I've used 8 elements on 70cm. I have tried several ways to increase the spacing, but MMANA-GAL does not indicate any advantage. I have recently tried a simulation of 70cm inside a 2m skeleton slot with MMANA-GAL, and there is little interference with either pattern or impedance. Gain Enhancement of Waveguide Slot Antennas Using Quasi-TEM ...

KEYWORDS: Bowtie antenna, Broadband, High gain, HFSS, loss reduction. I. INTRODUCTION . Printed slot antennas offer an attractive solution to compact, conformal, and low-cost designs of many wireless application systems [1] due to small size, light weight, low cost, good performance, and low profile [2].
