TL;DR: In this paper, a small broad-band internal antenna for IMT-2000 mobile handsets was designed by introducing substrates of low dielectric constants and electromagnetically coupling two shorted microstrip patch elements, of either rectangular or semidisc shape.

TL;DR: In this paper, the authors developed a compact and broadband microstrip patch antenna for the IMT-2000 mobile handset application by parasitically coupling two shorted semi-disc patches with a single shorting-post each and employing Styrofoam substrate with low dielectric constant, an overall impedance bandwidth of 17.8% was achieved to cover the frequency spectra of 1.862-2.225 GHz.

TL;DR: In this article, a square microstrip patch antenna with broadband operation is demonstrated, which achieves an impedance bandwidth (return loss /spl les/-10 dB) of 67.5%.

TL;DR: In this paper, the authors present electromagnetic coupling of an electrical fast transient plane wave penetrating through slots or apertures perforated in one side of a shielding metallic enclosure, which includes a single slot of different length, a single aperture of different width, multiple-angular aperture of different geometry, multiple cell aperture of various cell numbers, multiple thin slots, an aperture-cell array making up the whole side of the enclosure, and a miscellany case simulating a PC main frame.

TL;DR: In this paper, the coupling cross section and the shielding effectiveness of a 1.25 m-length RG 58 C/U 50Ω coax are measured by employing both the mode-tuned reverberation chamber and GTEM cell methodologies.
