A method to efficiently compute the input impedance of the coaxial probe fed microstrip antennas by using characteristic modes is proposed in this paper. The efficiency is achieved by defining a discontinuous source current at the feed location that models the current injected by the probe. The input impedance is simply expressed in terms of modal excitation coefficients and eigenvalues of each mode.

A Near State PWM Method With Reduced Switching Frequency And Reduced Common Mode Voltage For Three-Phase Voltage Source Inverters Un, Emre; Hava, Ahmet Masum (2007-05-05) The Near State PWM (NSPWM) method, which reduces the common mode voltage/current, is proposed for three-phase PWM inverter drives. The optimal voltage vectors and their sequences are determined. The voltage linearity and DC bus and AC output PWM current ripple characteristics are studied. The method is thoroughly investigated and its performance is compared to conventional methods. Theory, simulations, and experiments show that NSPWM exhibits superior common mode and satisfactory PWM ripple performance char...
Design of Irregularly Shaped Patch Antennas by using the Multiport Network Model Sener, Goker; Alatan, Lale; Kuzuoğlu, Mustafa (2008-07-11) The multiport network model (MNM) is an analytical method that is used to analyze microstrip antennas. MNM is based on defining ports along the periphery of the patch and evaluating the impedance matrix corresponding to these ports by using the Greenpsilas function for the cavity under the patch. For regular rectangular, triangular and circular patches, analytical expressions for the Greenpsilas function are available. In the analysis of irregular patches, Greenpsilas functions cannot be calculated explicit...
A High-Performance PWM Algorithm for Common-Mode Voltage Reduction in Three-Phase Voltage Source Inverters Hava, Ahmet Masum (2011-07-01) A high-performance pulsewidth modulation (PWM) algorithm with reduced common-mode voltage (CMV) and satisfactory overall performance is proposed for three-phase PWM inverter drives. The algorithm combines the near-state PWM (NSPWM) method that has superior overall performance characteristics at high modulation index, and MAZSPWM, a modified form of the active zero-state PWM method (AZSPWM1), which is suitable for low modulation index range of operation. Since AZSPWM1 has line-to-line voltage pulse reversals...
A Framework for Energy based Performability models for Wireless Sensor Networks Omondi, Fredrick A.; Shah, Purav; Gemikonakli, Orhan; Ever, Enver (2015-03-27) A novel idea of alternating node operations between Active and Sleep modes in Wireless Sensor Network (WSN) has successfully been used to save node power consumption. The idea which started off as a simple implementation of a timer in most protocols has been improved over the years to dynamically change with traffic conditions and the nature of application area. Recently, use of a second low power radio transceiver to triggered Active/Sleep modes has also been made. Active/Sleep operation modes have also be...
A readout circuit for QWIP infrared detector arrays using current mirroring integration Tepegoz, M; Akın, Tayfun (2003-09-18) This paper reports a current mirroring integration (CMI) CMOS readout circuit for high-resolution Quantum Well Infrared Photodetectors (QWIPs). The circuit uses a feedback structure with current mirrors to provide stable bias voltage across the photodetectors, which can be adjusted between 0 V and 3.5V. The photodetector current is mirrored to an integration capacitor which can be placed outside of the unit pixel, reducing the pixel area and allowing to integrate the current on larger capacitances for large...
