In this article a low cost, efficient and high flexible dual band slotted patch antenna has been designed
for point to point and broadband high-speed wireless communication. For high data rate transmission and wideband
spectrum, a low resistivity silicon substrate has been used having relative permittivity of 11.9, thickness of 0.275 mm
and tangent loss of 0.002. The proposed slotted patch antenna has been designed for millimeter wave band operating
at 57.52 GHz (V-Band) and 70.64 GHz (E-Band) applications. Two inverted U-shaped slots have been introduced on
both sides of the patch to get the dual band operation. The Jerusalem-shape slot is used for achieving good impedance
matching and better bandwidth. The antenna achieved a wide bandwidth of 1.82 GHz and 1.06 GHz with a maximum
gain of 4.546 dB and 2.770 dB at 57.52 GHz and 70.64 GHz, respectively. The antenna achieves a radiation efficiency
of 89.68% and 93.21% at 57.52 GHz and 70.64 GHz frequency bands respectively. The overall size of the antenna is
2.36x2.63 mm2
and can be used in portable gigabit speed applications
