“…In these design cases, the patch's two broadside radiation patterns in the E-and H-planes with polarization diversity are obtained. Also, it is noteworthy that by exciting different resonant modes of the same patch, broadside and conical radiation patterns with pattern diversity can be achieved for dual-polarized patch antennas [6][7][8][9]. However, to function at the same frequencies, the modified patch structures or use of the external feeding networks become necessary, which make these designs more complicated.…”

“…In this paper, the antenna type is substantially different from the conventional, dual-polarized patch antennas using two orthogonal feed ports for polarization diversity [1][2][3][4][5] or exciting different resonant modes for pattern diversity [6][7][8][9]. Instead, a simple, dual-polarized oblong loop antenna is proposed for producing two uncorrelated waves for orthogonal polarization and pattern diversity in the laptop computer.…”

“…To the author's best knowledge, no or very scant studies using loops to achieve dual-polarization and pattern-diversity properties are available in the literature. Compared with the patch designs [1][2][3][4][5][6][7][8][9], the proposed loop design has a coplanar structure and can be easily fed using the coaxial cable (unlike bulky probe feed for patch). These attractive features are favorable for practical laptop antennas.…”

A compact, two-port, oblong loop antenna producing two orthogonal waves for fifthgeneration (5G) operation in the 3.4-3.6 GHz band with transmission coefficient (S 12 ) lower than −32 dB and excellent envelope correlation coefficient (ECC) less than 0.002 is introduced for laptop antenna applications. Unlike the conventional, probe-fed, dual-polarized patch antennas, the proposed design uses the loop antenna fed by the coaxial cables and has a coplanar structure. The loop antenna is placed 1 mm above the top edge of the display, has a compact size of 30 mm × 4 mm and two feed ports spaced merely 2 mm (about 0.02-λ at 3.4 GHz) apart. Port1 is designed as a coupling feed to the loop while port2 is a direct feed in the loop, all located along the loop's central line. With this feeding arrangement, port2 is located in the current-null region when port1 is excited, whereas maximum currents of port1 excitation are located in the current nulls of port2 excitation. These properties lead to two decoupled, orthogonal radiating waves with very low ECC. Additionally, due to the oblong structure of the loop, pattern diversity is also achieved. Details of the dual-polarized loop antenna for 5G applications are presented.
