Novel high gain dual band single aperture array with large cross-polarized isolation at Ku-band for the TT&C system of a geostationary satellite

Corporate‐fed advanced microstrip arrays with improved cross‐polar isolation: Design and engineering using DGS‐integration techniques

“…Communication systems demand antennas with high‐gain and polarization purity at low‐cost and microstrip arrays are an optimum choice. While the properties of individual element, mode of excitation, and physical arrangements are the determining factors in designing an array, feed network is an important point of consideration based on power handling and tolerable loss 1–10 . The microstrip‐feed has well‐known advantages for its compactness, low‐profile, and low‐cost; but its ohmic loss, radiation losses from junctions and discontinuities limit the achievable gain and cross‐polar (XP) isolations 10–15 .…”

[1][2][3][4][5][6][7][8][9][10] The microstrip-feed has well-known advantages for its compactness, low-profile, and low-cost; but its ohmic loss, radiation losses from junctions and discontinuities limit the achievable gain and cross-polar (XP) isolations. [10][11][12][13][14][15] XP radiations in microstrip-fed array and its control is the primary focus of this investigation.…”
