Design of a Low Profile and Compact Omnidirectional Filtering Patch Antenna
A low profile omnidirectional patch antenna with filtering response is investigated in this paper. The triangular patch antenna is axially fed by a probe at its center, exciting both its TM10 and TM11 modes. Comparing with the traditional circular patch,

Wideband Omnidirectional Slotted Patch Antenna With Filtering Response
A wideband omnidirectional patch antenna with filtering response is investigated in this paper. The circular patch antenna is centrally fed by a probe, with its TM01, TM02, and TM03 modes simultaneously excited. Two ring slots are meticulously introduced

Nondestructive Testing of Welded Composite Metal Foams
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.

Quasi-Real Scenario of Reconfigurable Filtering Functions Antenna for UWB Communications
In this paper, an Ultra Wide Band antenna with reconfigurable filtering-characteristic is proposed to overcome interferences problems in the frequency range 3.1 GHz–10.7 GHz. With dimensions of 35 x 35 mm2, the structure is simple, low–cost and possesses

Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...

X-Band Waveguide Reflectionless Filtering Antenna Array With High Selectivity
In this paper, a waveguide reflectionless filtering antenna array with high selectivity is proposed. Instead of reflecting the out-of-band signal back to the source, the proposed antenna array dissipates the energy through a lossy network, which can ...
