A High Gain and Wideband Narrow-Beam Antenna for 5G Millimeter-Wave Applications

Blog Article

A wideband antenna with a high gain and narrow beam-width for future 5G communication systems is presented in this research.The antenna operates in 28 GHz 5G band with a large 35.53% bandwidth ranging from 23.

41-33.92 GHz.The array has 4-elements arranged in a linear fashion to attain a high gain of 10.

7 dBi.It radiates along its end-fire direction and provides a very Goalie - Goalie Mask - Junior narrow beam-width of 14.6° in its H-plane.

A corporate feed network specifically designed for thin substrates was used in order to excite the array elements.It is built upon thin 0.254 mm Rogers substrate Air Freshener to minimize transmission losses and attain high radiation efficiencies of more than 90% throughout its operating frequency range.

It has a compact structure bearing low cost and is easy to fabricate.This antenna fulfills necessary requirements of 5G communication and is therefore a good candidate to be used in the millimeter-wave range.
