Antennas: Cavity-Backed Slot Antennas - Antenna Theory
How Antenna Gain affects Range in FPV - Oscar Liang Understand Antenna Gain. Antenna gain is the measure of antenna power in decibel (dB), which is equal to 10*log(Pout/Pin). Don’t worry about it, just remember that the higher the gain, the more directional an antenna is – more range, narrower beam width. Every 6dB increase in antenna gain, should in theory, doubles the range. Gain enhancement of a slot antenna with a metamaterial ... Abstract: This paper presents a technique to increase the gain of a slot antenna with the help of a single layer metamaterial (MTM) superstrate. The gain enhancement is achieved using the zero-index property of the metamaterial. The increased broadside gain for the proposed antenna is 6.42dB more in comparison to that of the reference slot antenna. A high gain S-band slot antenna with MSS for CubeSat ... 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.
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. An I-shaped microstrip line is used to ...
