A dipole antenna is easy, right? Two wires, each a quarter wavelength long, emanate from a coax or other feedline. Unless it is an off-center dipole. The length is still the same, but you move the ...

Take an afternoon drive around an urban or suburban area anywhere in the Midwest. Look at the houses. What is missing from these homes that would likely have been there 50 years ago? Give up? How ...

After moving and installing an anechoic chamber, we needed to test the shielding effectiveness. We decided to build a matched set of 900 MHz Dipole antennas. We started by designing a half wave dipole ...

Airgain extends product portfolio to provide high performance connectivity for the next generation of 5G NR sub-6GHz IoT and M2M applications The OMNIMAX Next Dipole series includes 5G NR sub-6GHz ...

A dipole antenna using antenna traps is desired which is to be used to transmit a 140 MHz signal and a 90 MHz signal. Design the antenna assuming a velocity factor of 0.90. First find the wavelengths ...

Much of the work of Spectrum Planning Group is based on well-established principles of 'antennas and propagation'. Propagation matters have received a lot of attention over the years and much has been ...
