“…A radial stub is used to provide a broadly resonant RF short circuit. When cascaded with high impedance quarter wavelength transmission lines the radial stub provides an effective decoupling network for microwave amplifiers and other active components [6]. The high impedance (selected as 130) quarter wavelength (with electrical length 900) microstrip line is followed by a radial stub.…”

-This paper reports design of a multiband RF transceiver for simultaneous operation at 2.44 GHz and 5.25 GHZ. The specific choice of the frequency is to meet the WLAN applications. The basic aim of the proposed design is to reduce the component count, to achieve power saving with a compact size. The proposed transceiver is devised by using indigenously deigned dualband circuits and off the self-laboratory equipment's. The entire transmitter structure is implemented using hybrid microwave integrated circuit (HMIC). The proposed multiband transceiver exhibits a link budget of -64 dBm and link margin of 74 dBm, the implemented transceiver exhibits an EMR of 1.5x10 -7 for concurrent dual-standard WLAN application. Hence, the proposed transceiver is efficient as well as safe for the human operation.

Abstract-Low-Loss resonators with high Q factor have special importance in modern microwave telecommunications systems. In this paper, a modern dual-band CSRR with high Q factor is first examined using SIW technology on a surface waveguide. It should be noted that the proposed structure paves suitable way for emitting and propagating wave in two passing bands (approx. 4.7 and 5.3 GHz) below cutoff frequency waveguide. High Q factor and its high small-sized percentage is the salient specification of this structure as compared to other similar planar resonators proposed in various references.At the end of this paper, three applications of this resonator are studied in designing a small multiband filter with high Q factor, a small multi-band diplexer with low passage bandwidth and a planar oscillator with low-phase noise. According to the scientific literature, the proposed oscillator was found to enjoy the best performance at low phase noise for planar microwave oscillators.

In this letter, a broadband coupler is presented that makes use of a corrugated half mode substrate integrated waveguide (CHMSIW) technique using a printed circuit board process. The coupler is realized by parallel CHMSIW lines where the vias to form the sidewalls of the HMSIW are placed with the open-circuit quarter-wave-length microstrip stubs and the energy couples by magnetic field. Compared with conventional SIW coupler, it is easily integrated with active devices because it can isolate better the CHMSIW input/output ports from the ground plane. The coupler is simulated and measured at 9.5-17.5 GHz. The result of measurement shows a good agreement with the result of simulation.
