Or perhaps you have never heard of (or are a little rusty) on the above parameters. Well then, you've come to the right place. Before we can design an antenna or discuss antenna types, we must understand the basics of antennas, which are the fundamental parameters that characterize an an...
Need a simple, nearly invisible wire antenna with reasonable gain, low angle radiation (for DXing) and multiband capabilities? Check out this long-overlooked design that requires no antenna tuner. PDF file. Loop AntennasThe loop antenna comes in an amazing number of configurations. It is a "...

ratios are even higher than the F/B ratio. You can see the deep notches in the radiation pattern in figure 2 that indicate this is where the greatest rejection of signals occurs. It may not be directly at the side of the beam, it is mainly dependent on antenna design (spacing, length...
In order to satisfy in the construction process the communication demand, 280 rows provided 96 vehicles to carry the broadcasting station and 306 hand-hold broadcasting stations, and primarily the vice-battalion control room has provided the markup profit antenna, has guaranteed between the work uni...
This article summarizes the design issues with and the interfacing of these devices into complete radio systems. What is the Radio? Traditionally, a radio has been considered to be the ‘box’ that connects to the antenna and everything behind that, however, many system designs are segmented ...
As part of my project, I had to imitate the circular scan of the analog display while transferring the receiver signal to the video frame buffer. To achieve this, I utilized a ROM to transform the antenna's reported angular position into sine/cosine values, which were then utilized to gener...
RF amplifier can be used for various functions in the communication chain. For providing gain to the signal before transmission it is called as power amplifier and will be connected to the transmitting antenna. When it is connected just after reception of the signal it is called as Low Noise ...
decrease from zero, which allows the impedance to drop to a more desirable value. The same is true on the IFA antenna. Hence, the feed location is a critical factor in designing an IFA or slot. A good location for the feed can easily be obtained experimentally during an antenna design. ...
