Metallic components such as USB connectors used in mobile phones can easily affect the performances of antennas placed nearby. This paper illustrates the use of the metallic USB connector in a very compact loop antenna with a volume of 5×8×60 mm3 to generate an additional resonant mode at about 3.13 GHz. A standard metallic USB connector is placed inside the loop radiator of the antenna to generate...
In this paper, a new design of microstrippatch antenna based on grid structure in the Ka-band is proposed which can realize optical and microwave coaxial detection. Both the patch and ground boardis designed into dense grids, at the same time, using the transparent glass as the medium plate. As is shownin the simulation results, in this concerned wave band, compared with ordinary microstrip patch...
