What r the advantages and disadvantages of slot antenna - Answers
Slot Antenna. Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz. They are often used in navigation radar usually as an array fed by a waveguide. But also older large phased array antennas used the principle because the slot radiators are a very inexpensive way for frequency scanning arrays. .

2017-5-18 · Fixed beam antenna has fixed gain profile with a primary lobe pointing in a single direction. We only can steering the beam by changing the orientation of the antenna physically , which permit relatively slow changes at best. This kind of antenna does provide high gain for their cost and are widely deployed in practice. What is the advantage of using a helical antenna over a Thanks for the A2A. Helical antennas can be made to operate one of two ways, normal-mode helical and axial-mode helical, which both have specific advantages over a straight monopole antenna. Normal-mode helical: The antenna is the same length as...
