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 planar dual-band antenna using off-centered feed structure is proposed and investigated. The antenna consists of an off-centered dipole and an asymmetrical slot radiator. Design guidelines of the antenna are drawn and design principle is analyzed first. By properly selecting the feeding position, an operating frequency band of 2.47 to 2.53GHz and 4.14 to 13.76GHz for return loss larger than 10dB...
Design concept of an implantable, balanced slot-dipole composite antenna is proposed and simulated. The antenna is composed of a tapered slot element and a symmetrical dipole and embedded in a planar stratified phantom. The reflection coefficiency, radiation pattern and gain of the antenna are simulated. It is shown that the antenna can operate at 402–405MHz, 433MHz, 902–928MHz and 2400–2500MHz bands...
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...
A novel wideband polarization diversity antenna without parasitic elements is proposed. The diversity antenna is simply composed of a balanced, printed dipole and a modified tapered slot antenna.

As will be reported, the diversity antenna's operation bandwidth is from 5.04–11.85 GHz, in which the average isolation between the...
Design concept of a novel, dual-band balanced antipodal ultra-wideband antenna is proposed. The antenna is composed with a symmetrical dipole and balanced tapered slot radiators and can be directly integrated with differential microwave circuits. Operation principle and performance of the antenna, such as return loss, radiation patterns and gain, are simulated and analyzed. As will be presented, the...

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...
