“…In these structures, a combination of two different feeds is observed. These feeds are composed of two separate microstrip lines [15], two apertures [16], one via and onemicrostrip [17], two separate probes [18], and one microstrip and one aperture [19]. Other designs with a single electromagnetically coupled feed are also available [20], [21].…”

A new design of dual band compact microstrip antenna is proposed for Ku-band applications.Dual band is achieved using three pairs of thin slits from the sides of a rectangular patch and feeding with a microstrip feed line.The result shows that a return loss of -32.9dB is achieved at the first resonant frequency of 12.72GHz, and -14.4dB is obtained at the second resonant frequency of 14.4GHz frequency with VSWR ≤ 2indicating improved matching conditions. The results ofsimulation are return loss, radiation pattern, VSWR, and band widtharepresented. The design is performed by using Ready-madeSoftware package Zeland-IE3D. The antenna is fabricated using thin film and photolithographic technique and measured using the Vector Network Analyzer. The final result shows that good agreement between the simulated and measured results.

In this paper, a new dual band dual polarized probe fed Dielectric Resonator Antenna (DRA) exciting by substrate integrated waveguide (SIW) is presented. The design is based on the degenerated modes TE 102 and TE 201 , which are co-exist in the SIW square cavity and adjustedby a corner cut. In the proposed antenna only one input port is used for two bands and to avoid parasitic radiation, the DR is located on the ground plane and fed by two probes which are placed in regions of maximum electric field. Simulation and results exhibit excellent performance with a cross-polar level of 17 dB lower than to that of the co-polar level and gain of 3.7 dBi at 5.91 GHz and a cross-polar level of 11 dB lower than that of the copolar level and gain of 4.7 dBi at 6.37 GHz.

“…Many designs of dual-polarized patch antennas have been reported, and a variety of feeding techniques to achieve high isolation and good cross-polarization levels have been demonstrated (Lindmark et al, 1998;Barba, 2008;Rowe & Waterhouse, 2003;Gao et al, 2001;Adrian & Schaubert, 1987;Padhi et al, 2003;Kim et al, 1999;Wong & Chiou, 2002). The related feeding techniques include two aperture-coupled feeds with centrally located crossed slots (Lindmark et al, 1998;Barba, 2008;Rowe & Waterhouse, 2003) or two off-center orthogonal coupling slots (Gao et al, 2001;Adrian & Schaubert, 1987;Padhi et al, 2003) and hybrid feeding structures (Kim et al, 1999;Wong & Chiou, 2002). In Kim et al (1999), a microstrip line feed and a microstrip line-probe feed have been used to achieve dual polarization, while a capacitively coupled feed and slot-coupled feed are used in Wong and Chiou (2002).…”

Results in the two references show that the hybrid feeding structures can greatly improve the isolation of the antenna.…”

A new dual-polarized microstrip patch antenna fed by probe feed and aperture coupled feed is presented. The hybrid feed, a T-shaped microstrip feedline, is adopted to improve the isolation between two ports, and the "hour-glass" shaped slot is used to improve the input impedance of the proposed antenna. The measured center frequency is 2.37 GHz, the return loss for port 1 is 16.08 dB and 21.92 dB for port 2, and the isolation between the two ports is 24.24 dB. Finally, four slots are embedded along the centerline of the ground plane so that the bandwidth of antenna is greatly improved. Good agreement between the measured and simulated results has been achieved.
