In this paper, a novel and compact ultra-wideband (UWB) bandpass filter with a narrow notched band in the UWB passband using broadside-coupled microstrip-coplanar waveguide (CPW) structure is presented. To avoid the interference with the WLAN system, the operation band centered at 5.8 GHz (5.725–5.825 GHz) is notched by embedding open stubs in the(More)
A novel dual-band E-shaped monopole antenna is proposed for wireless applications in the 2.4/5.2GHz bands. To obtain the dual-band characteristic, two L-shaped stubs are added to a traditional monopole antenna. The proposed antenna is fed by coplanar waveguide. The antenna is simulated and measured. The measured results show that operating bands of the(More)
This paper presents a compact multi-channel receiver front-end using system-in-package (SiP) integration technology. In the circuit linking design, a power divider network is introduced to keep the amplitude consistency of the local oscillator (LO) signal for each channel. The embedded low temperature co-fired ceramic (LTCC) RF filter equipped with two(More)
