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. Enhancing the Bandwidth of a Microstrip Patch Antenna ... Keywords: - bandwidth, dielectric constant, microstrip antenna, slot patch, substrate I. INTRODUCTION Communication can be broadly defined as the transfer of information from one point to another [1]. Communication between human beings was first done through voice. With the desire to increase the distance of 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 ...
