“…With the development of ultra wideband (UWB) technology for short range and high data rate communications [1], many UWB antennas [2][3][4][5][6][7] have been designed to work on the frequency band ranging from 3.1 GHz to 10.6 GHz. Besides exploiting the UWB operating band from 3.1 to 10.6 GHz for wireless personal area network (WPAN) applications, the current users of WPAN are also eagerly demanding a super wideband (SWB) to cover both short-and longrange transmission for future UWB communications.…”

Abstract-A super-wideband antenna based on a propeller shaped printed monopole with a CPW feed is presented in this paper. The enhanced bandwidth is obtained by modifying the disk of a conventional circular disk monopole to resemble a propeller. This design produces an extremely wide impedance bandwidth from 3 to 35 GHz with an impedance bandwidth ratio of 11.6 : 1. The gain of the proposed antenna varies from 4 dBi to 5.2 dBi. The antenna has fairly stable radiation characteristics throughout its operating band. The developed prototype is fabricated and measured. Simulation and experimental results are in good agreement.

“…However, the results from this technique showed that the antenna bandwidth cannot be enhanced more than few tens of a percent [6]. Other types of ultra-wideband microstrip antennas have been developed using different feed lines, such as microstrip line [7][8][9], coplanar waveguide (CPW) [10,11].…”

Abstract-In this paper, the design of a printed circuit antenna based on lotus flower patch of a miniaturized profile is proposed. The antenna consists of three layers including a patch and a ground plane of a thin copper layer separated by a Roger RT/duroid R 5880 substrate for high gain-bandwidth product applications including microwave imaging systems. The patch structure is patterned with triangular defects to provide a fractal structure. Nevertheless, the ground plane is defected with Electromagnetic Band Gap (EBG) structures. The antenna is found to show a first resonant mode around 3 GHz, while the other frequency modes are obtained around 4.2 GHz and 6 GHz which are below −10 dB. Moreover, the antenna operates over the frequency range from 7.8 GHz up to 15 GHz with a bore-sight gain varing from 4 dBi up to 6 dBi when operates in free-space environments. The antenna size is reduced to a 32 mm × 28 mm × 0.5 mm using shorting plates on the substrate edges. The antenna performance characteristics are examined using CST and HFSS commercial software packages, which are based on the Finite Integration Technique (FIT) and the Finite Element Method (FEM), respectively. Finally, the antenna performance is tested experimentally for both S 11 spectrum and radiation patterns to show an excellent matching with the obtained numerical results.

Abstract-The design and performance of a circularly polarized microstrip patch antenna, for the application in Wireless Local Area Network (WLAN), are reported here. The antenna is a proximity coupled microstrip patch antenna where the radiating patch is loaded by a V-slot. This miniaturized microstrip antenna has wide bandwidth in the frequency band of WLAN and exhibits circularly polarized far field with very good axial ratio bandwidth. The simulated results using IE3D software are verified by measurement.
