Microwave Resonators and Filters for Wireless Communication

Abstract

The Springer Series in Advanced Microelectronics provides systematic information on all the topics relevant for the design, processing, and manufacturing of microelectronic devices. The books, each prepared by leading researchers or engineers in their fields, cover the basic and advanced aspects of topics such as wafer processing, materials, device design, device technologies, circuit design, VLSI implementation, and subsystem technology. The series forms a bridge between physics and engineering and the volumes will appeal to practicing engineers as well as research scientists.

Compact Reconfigurable Uwb Antenna Integrated With Stepped Impedance Stub Loaded Resonators and Switches

“…According to the rule and theory of SIS-SIR and SIS-HSIR filter [16], the proposed reconfigurable UWB antenna has been optimized using HFSS. Two ideal switches with length 2 mm and width 0.3 mm are employed in simulation and measurement.…”

“…The notched UWB antenna consists of a polygon wide slot, a hexagon radiation patch, a SIS-HSIR etched inside the hexagon radiation patch, a SIS-SIR embedded in CPW transmission signal strip line and a 50 Ω CPW feed structure. The resonator frequency of the two resonators SIS-HSIR and SIS-SIR can be calculated using resonator theory [16]. First, a wide slot UWB antenna is designed based on previous design proposed in [11].…”

Design Filters Using Tunable E-Shaped Dual-Mode Resonators for Lower-Ultra-Wideband and Upper-Ultra-Wideband Applications

“…Figure 1(b) shows the improved tunable E-shaped dual-mode microstrip resonators. In this improved structure, stepped impedance resonator (SIR) [28][29][30][31] is used in stead of uniform half-wavelength resonator which can provide additional characteristic admittance Y 3 and electric length θ 3 for tuning resonance frequency more flexible. The open-circuited stub at the centre of the E-shaped SIR introduces another transmission pole near the fundamental resonance frequency of the SIR.…”

Compact Split Ring Sir Bandpass Filters With Dual and Tri-Band

“…For the split ring tri-section SIR as shown in Fig. 1(c), according to the relative procedure in [13], if k 1 = Z 3 /Z 2 , k 2 = Z 2 /Z 1 , and the total electric length can be got as…”
