bandwidth refers to the amount of the frequency spectrum that a signal resides in.example, the spacing between channels on radio are determined by their bandwidth.
beamwidth is a physical characteristic of an antenna. they generally mark the point bore sight of a directional antenna that are at -3dB or half power

How Radar range related to Antenna gain?
Radar range is affected by various factors, including the transmitted power, beamwidth, frequency, propagation losses, and antenna gain. Antenna gain plays a crucial role in determining the effective range of a radar system, as it focuses the transmitted energy in a particular direction, increasing the signal strength in that direction and consequently extending the radar range. A higher antenna gain typically results in a longer radar range by improving the system's ability to detect and track targets at greater distances.
What is grid antenna?
A grid antenna is a type of directional antenna characterized by its mesh-like structure, typically made from metal rods or wires arranged in a grid pattern. This design enhances its ability to focus radio frequency signals, making it highly effective for applications such as satellite communication, amateur radio, and point-to-point links. The grid design minimizes wind load and allows for high gain and narrow beamwidth, improving performance in specific directions.
What is unity gain antenna?
an antenna with 0 gain. What you hear and transmit is what you get from your 2-way radio.
What factors determine antenna gain?
It depends upon the type of antenna. For example, a Yagi antenna's gain can be increased by adding elements. A parabolic antenna's gain can be increased by increasing the diameter of the antenna. All antennas can have their gain increased by lowering the loss of the feed line. By replacing regular coaxial cable with nitrogen pressurized coax, the overall gain at the receiving end can be increased. Gain can also be increased by inserting an amplifier between the antenna and the receiver. Another method of increasing gain is to reduce the VSWR, or voltage standing wave ratio.
What is the relation between bandwith and gain?
The product of bandwidth and gain is constant. If bandwidth increases then gain decreases and vice versa.
When antenna diameter is doubled what will happen to antenna gain?
increases by 6 dB
The of an antenna depends upon the frequency of the RF signal and the gain?
The size of an antenna depends upon the frequecny of the RF signal and the gain.
What is the effective radiated power formula?
EIRP (Dbm)= Output Power(Dbm)-Losses(from cables & adapters)+Antenna Gain(Db)
What is gain of typical TV FM vhf only home antenna?
The actual numbers are not as important as the knowledge that generally speaking, the larger the antenna the more gain it will have. Three other main factors are the Distance from the transmitting antennas are from your location and the Height of your antenna above the ground and what Obstructions there might be between the two antennas.
What is microstrip patch array antenna?
microstip patch array antenna is basically ,thecollection of antenna that give the double directive gain
If antenna is passive than how can it add gain?
Antennas provide so called passive gain, which means it comes from particular shape of the antennaThe gain of an antenna is a passive phenomenon - power is not added by the antenna, but simply redistributed to provide more radiated power in a certain direction than would be transmitted by an isotropic antenna. If an antenna has a gain greater than one in some directions, it must have a gain less than one in other directions, since energy is conserved by the antenna.SOURCE: wikipedia.com
