I'm constructing a biconical antenna which is to operate in the 30MHz-3GHz frequency range (yes, its sizable!). I'm curious as to the best type of balun to implement as well as the best connector system to use.
Find attached a diagram of the antenna. Side-length is 30cm, and conical half-angle...
Yes, i'm using CST's transient domain solver, which apparently is very robust for wideband simulation purposes.
Erronous frequency is not the highest. Petals are evident at even the lower end of the frequency range when i'm using an exponentially tapered conical shape (think of back-to-back...
I'm in the process of developing a wideband antenna for EM monitoring applications. It is to be omnidirectional, and have as even a possible radiation pattern both vertically and in azimuth.
I'm currently using CST to design the antenna, and am experimenting with different profiles, such as a...
As per polarisation requirements, the received signal is likely to be vertically polarised, however a circularly polarised antenna like a spiral antenna will allow the provision of horizontally or circularly polarised signals to be recieved as well (in the case of vertical and horizontal...
Unfortunately a 50" high antenna is not feasible for my application. My antenna needs to be compact (will be mounted on a cart), and is to measure the signal intensity for a variety if heights above ground. Hence, small size is a priority. That's the main reason why i though a series of planar...
To what accuracy? As high as possible. Azimuth (H-plane) radiation pattern should be as omnidirectional as possible.
I was investigating using a discone antenna to obtain uniform omnidirectionality, however its impedance matching characteristics is poor at lower frequencies (S11 is large)...
Hey guys.
I'm planning on constructing an antenna array for receiving RF signal strengths which i want to measure. The array is omnidirectional and will use a series of high-gain unidirectional antennae mounted around an axis facing outwards. I have a RF receiver.
How can i feasibly multiplex...
