"Via-Less” UWB Filter using Patched Microstrip Stubs
(VSP (imprint of Brill), 2009)
This paper presents an Ultra-Wide Band (UWB) microstrip filter which is initially modeled from a quarter-wavelength short-circuited stubs, without the use of any vias. All vias that provide short circuit stubs are replaced ...
X-band trisection substrate-integrated waveguide quasi-elliptic filter
(EMW Publishing, 2008)
A narrowband trisection substrate-integrated waveguide elliptic filter with coplanar waveguide (CPW) input and output ports is proposed and demonstrated for X-band applications. The filter is formed by incorporating ...
Novel compact "via-less" ultra-wide band filter utilizing capacitive microstrip patch
(EMW Publishing, 2009)
This paper presents a novel compact "via-less" UWB filter derived from a quarter-wavelength short-circuited stubs model. In this compact "via-less" UWB filter, there is no connecting vias as short circuit elements. Unlike ...
Dual frequency integrated antenna (DFIA) with image rejection
(Institute of Electrical and Electronics Engineers (IEEE), 2005)
A new configuration of integrated antenna featuring dual frequency operations and image frequency rejection is implemented. The used of dual frequency for image rejection in one system by using one antenna is a new technique ...
Novel compact microstrip ultra-wideband filter utilizing short-circuited stubs with less vias
(EMW Publishing, 2008)
We present here a new pattern with compact size of Ultra Wideband (UWB) microwave filter. The filter is based on quarter-wave length short-circuited stubs model. We introduced here a new schematic model by extracting all ...
Small antenna efficiency by the reverberation chamber and the Wheeler Cap methods
(Institute of Electrical and Electronics Engineering (IEEE), 2005)
Two methods of determining an antenna's efficiency are compared. Each of these methods was used to measure the efficiency of three different antennas (two monopole antennas with attenuator and surface mount resistor, and ...
A comparative study of small antenna efficiency measurements
(Institute of Electrical and Electronics Engineering (IEEE), 2005)
Three methods of determining an antenna's efficiency are compared to measure the efficiency of three different antennas (two monopole antennas with attenuator and surface mount resistor, and modified folded monopole patch ...
Performance analysis and prediction using circuit model in a microstrip patch array
(Institute of Electrical and Electronics Engineering (IEEE), 2007)
This work is an effort in investigating and modeling an accurate Circuit Model derived from the Transmission Line Method (CM/TLM) by simulating a rectangular microstrip patch array using two different simulation techniques, ...
Performance modeling and simulation of microstrip dipole array antenna for WLAN application
