“…At present, most SAAs can only achieve dual-bands, and the typical structures are perforated type [4][5][6][7][8], interleaved type [9][10][11], as well as the latest proposed shared element type [12]. However, there is not much literature on TB SAA due to the difficulty of array arrangement.…”

In this paper, an S/C/Ku triple-band (TB) dual-polarization (DP) shared aperture array (SAA) with an approximate frequency ratio of 1 : 1.8 : 4.5 is proposed. An S/C dual-band dual-polarized (DBDP) perforated patch antenna is designed as a shared element, and the S-band array consists of S-band-working shared elements. The C-band array interlaces with C-band-working shared element and C-band cross-patches with phase compensation. The Ku band array consists of dual-polarization rectangular dielectric resonator antennas (DRAs) for its small section area and high design freedom. In order to ensure the symmetry of the structure, all the ports adopt a vertical welding structure. A 1 × 3 prototype array is fabricated and measured, showing that the S-, C-, and Ku-bands obtain the bandwidths of 2%, 2.1%, and 1.8%, respectively. The polarization isolation is better than 20 dB in all three bands, while the cross-polarization is lower than −20 dB. The proposed array has the advantages of low cost and high integration; moreover, the proposed array owns excellent potential for expansion to large aperture benefited from its symmetry.

“…Different researchers have developed antenna designs for L/C [10,11], L/X [12], L/S/X [13], and L/S [14] by aperture sharing. Independent dual band or triple band operations are obtained by designing and exciting individual antenna elements for each band and placing the antenna elements in stacked configuration, thus increasing the overall size of antenna.…”

A dual mode shared aperture antenna consisting of two planer arrays of ring antennas is designed for L and S bands. The array of larger dimension surrounds the array of smaller dimension. The antennas are isolated from one another and fed separately. The antenna dimensions are optimized and prototyped. The antennas radiate separately in L and S bands with least coupling or no coupling. Measured results are in agreement with the simulations, depicting good performance in terms of impedance bandwidth, isolation, and gain.

“…For large separation between the bands, reconfigurability is required at antenna element and at array topology level to adapt the array. Only a very limited number of reconfigurable or dual-band antennas have been designed for array applications in the last decades [14][15][16][17][18][19][20][21][22][23][24]. To date examples of multi-band antenna arrays with both a frequency ratio beyond 2:1 and 2-D scanning capability of more than ±45° in both bands are very limited in open literature [25][26][27].…”

A frequency reconfigurable phased array element is presented. The operational band of the single port L/S-band antenna can be selected by modifying the element apertures with p-In diode switches. The antenna element satisfies strict requirements on its frequency band separation (2.2:1), size, feeding structure and control lines to be integrated into a phased array system. A multi-scale array topology is proposed to achieve wide angle scanning (±60°) in both operational bands of the array.
