Conceptual design of a novel multi-resonated complementary antenna is proposed. By perpendicularly incorporating an offset microstrip-fed slot radiator and a symmetrical aperture-dipole element, the dominant one half-wavelength mode and two fractional-order dipole modes, i.e., the three quarters-wavelength mode and seven quarters-wavelength mode can be excited and triple-band operation can be obtained...
A novel cavity-backed microstrip-fed multislot antenna (CBMSA) for wideband application is proposed. The antenna is simply fed by a microstrip line terminated with a wide rectangular stub. By incorporating multi-slot configuration and backed cavity, unidirectional beam can be obtained within a broad bandwidth. The return loss, radiation pattern and gain over the antenna's operational bandwidth have...
This paper, a novel half-folded antipodal slot antenna fed by microstrip line is proposed. A half-folded tapered slot and patch-like tuning stub is employed to achieve both wideband and low cross-polarization performance. For comparison, a reference rectangular slot antenna fed by microstrip line is also designed, fabricated and measured. As is reported, the operation bandwidth of this antenna is...
A novel half-folded antipodal printed slot antenna fed by microstrip line with a tuning patch for wideband applications is proposed. Half-folded antipodal structure is employed to improve the radiation characteristics of the antenna. The antenna has been investigated numerically and experimentally and compared with conventional rectangular wide slot antenna. As is reported, the operation bandwidth...
An improved frequency notched ultrawideband (UWB) microstrip slot antenna with a square ring resonator embedded in the tuning stub is proposed. The antenna is investigated numerically and experimentally for its impedance matching property, frequency notched characteristic and radiation performance in detail. As will be reported, compared with conventional frequency notched slot antennas, after incorporating...
