How to increase gain of slot antenna

By Author

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 is lossy, the efficiency falls

What are the best techniques to increase the gain antenna ii) Gain of an antenna can also be bettered by partially cutting slots in the substrate and by employing multiple layer dielectric substrates. iii) A reflector can be used behind the antenna so that the EM waves after striking the reflector will form a unidirectional beam thereby increasing antenna gain. How can I increase the gain of a CPW fed slot antenna? The antenna is a spiral slot fed by a CPW. It has good impedance matching but its gain is 0 dBi. ENHANCEMENT OF BANDWIDTH AND GAIN OF A … The aim of the thesis is to design rectangular Microstrip Patch Antenna with enhanced gain and bandwidth and study the effect of antenna dimensions Length (L), Width (W) and substrate parameters relative 'ielectric constant (εr), substrate thickness (t) on the Radiation parameters of … How to increase antenna gain - Quora

In this video we learn what antenna gain is. At Solwise we offer a wide range of antenna both both indoor and outdoor use. We have antenna for 2.4GHz, 5GHz ...

Some other rubber ducky antennas use a spring of non-conducting material for support and comprise a collinear array antenna. Sector antenna - Wikipedia

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.
