Although conventional microstrip patch antennas have attractive features of easy fabrication and compatibility with MMICs, but they have a narrow bandwidth and large size in some of applications at low frequency bands [1]. In phased array applications, smaller antennas could be packed tightly to take advantages of lower angle scanning as well as reduction of mutual coupling [2]. Hand held communications...
The scavenging of electrical energy from surrounding environment has a number of attractions, and vibration energy is seen as one of the most potential sources. Switched damping is a method to improve the operational bandwidth of an electromagnetic energy harvester by alternatively switching the values of electrical damping coefficients of the device at different quadrants during oscillation. From...
A new meander open complementary split ring resonator (MOCSRR) particle was presented in this paper. The resonant frequency for the particle was 26.5 % lower than an OCSRR particle with the same overall dimensions. The resonant frequency was determined by simulating a CPW test structure in Momentum, modeling the MOCSRR particle with an equivalent circuit and measurements. Good agreement was observed...
In this paper, we present a design and simulation results of MEMS gyroscope using drive and sense electrode's voltage control to tune wide range resonance frequency that may yield robust vibratory MEMS gyroscope and at the same time retains the wide range of bandwidth. The design is of symmetrical shape for the proofmass and the branch-finger actuators. Branchfinger actuators in both drive and sense's...
