—The ground plane affects the characteristics of a planar inverted-F antenna (PIFA) significantly. Using the idea of the high-impedance surface to construct the ground plane, a new type of compact PIFA with a photonic bandgap type (PBG-type) ground plane is proposed. Both the traditional PIFA and the proposed antenna are analyzed using the finite-difference(More)
In this paper, we present the low noise amplifier using new feedback connection configurations. The UWB LNA is design in 0.18 Pm TSMC CMOS technique to achieve high gain, small size and low noise. The LNA achieved 11 dB of average power gain, low 2.87 dB noise figure (NF),-10.9 dB input match,-7 dB return loss,-3 dBm of IIP3 and only 0.54 mm 2 size with 15(More)
