“…2,4,5,7 Coupling techniques, different coupling methods such as L, T, Y, loop, are used in the design of broadband dipole antennas that matching the coupling element to the dipole plates has a direct effect on the coupling value. [2][3][4][5][7][8][9][10][11][12][13][14][15] The non-PCB techniques, these types of antennas are made only of metal sheets with slit that have high power tolerance and mostly used for large area radio coverage. [18][19][20] Cavity reflector techniques, in this method a variety of cavity reflectors are used to improve the antenna gain, directivity, and ratio of front-toback lobes.…”
