Dual wideband printed dipole antenna with integrated balun
نویسندگان
چکیده
A printed dipole antenna with integrated balun is presented. The radiating structure is a two-element dipole with resonances at 900 and 1700 MHz, with the balun providing one extra resonance at each band. By co-designing the radiating element with a Marchand balun modified for dual-band operation, an antenna covering the cellular bands 824–960 and 1710–2170 MHz has been achieved. Measurements on a fabricated antenna on low-cost FR-4 substrate show antenna efficiencies of .80 and .70% in the lower and upper band respectively. Despite the use of a dual-element radiator, the radiation pattern that is close to omni-directional H-plane is obtained.

Dual-Band Loop-Loaded Printed Dipole Antenna with a Wideband Microstrip Balun Structure
─ A novel loop-loaded printed dipole (LLPD) with a wideband balun structure is presented for aiming a dual-band antenna operation at 3.0/5.5 GHz bands. The proposed balun structure alone demonstrates VSWR<1.5 performance over a 3:1 bandwidth. As the loop elements placed on the antenna aperture provides dual-band operation with at least 15% impedance bandwidths, the wideband balun/feed allows fo...

A dual-band printed dipole antenna with integrated balun feed is given in this paper. First, the fork-shaped slot is etched on the arms of the printed dipole antenna to achieve the dual-band operation with resonances at WLAN bands. The radiating element without balun is optimized and operates at 2.4 GHz (2180–2750MHz) and 5.2GHz (5040 MHz–5480MHz) where return loss is less than −10 dB. In order...

Microstrip patch antennas are intrinsically narrow bandwidth devices, i.e. less than 10 %. Special techniques are always applied in order to increase their bandwidths. These include complicated wideband balun impedance transformers and parasitic elements. Abdelaziz reported a 10 GHz dual-element microstrip patch antenna design which was printed on a 1.6 mm thick Duriod substrate [1]. The two el...
