A compact gourd-shaped dual-band antenna for WiMAX/WLAN applications

Xiaotao Cai Anguo Wang Shun Gao

In this paper, a compact gourd-shaped dual-band antenna is presented. The proposed antenna mainly consists of two connected circular discs and a slotted stub extending from the upper circular disc. The designed antenna can support 3.5/5.5GHz WiMAX and 5.8GHz WLAN simultaneously. The simulated −10 dB return loss bandwidth of this dual-band antenna is from 3.0 to 4.0GHz and 5.4 to 6.4GHz. The antenna has good performance in impedance matching and the return loss can reach −54.7dB and −68.9dB at resonant frequency 3.5GHz and 5.8GHz, respectively. Moreover, the designed antenna can provide stable omnidirectional radiation patterns and a relatively flat gain trend within the dual-band. The effects of some important parameters on the antenna performance are analyzed. The simulation and measurement results of the antenna are presented, and a good agreement between them is achieved.

Miniaturized Triple-Band Antenna With a Defected Ground Plane for WLAN/WiMAX Applications

IEEE Antennas and Wireless Propagation Letters (2011)

Jing Pei Anguo Wang Shun Gao Wen Leng

A miniaturized multifrequency antenna is proposed. The proposed antenna can generate three separate impedance bandwidths to cover all the 2.4/5.2/5.8-GHz WLAN operating bands and the 2.5/3.5/5.5-GHz WiMAX bands. The proposed microstrip-fed antenna mainly consists of a circular ring, a Y-shape-like strip, and a defected ground plane. By adding a Y-shape-like strip in the circular ring, the antenna excites two resonant modes and is with miniaturization structure. Because of the introduction of the cambered ground plane with an isosceles triangle-defect, the third wide band with better impedance matching is obtained. A prototype is experimentally tested, and the measured results show good radiation patterns and enough gains across the operation bands.

Discussion on the Structure of Low-Temperature Radiant Heater of Gate Station

Applied Mechanics and Materials (2014)

Shun Gao Hong Yu Li Yong Shi Dan Yan Rong Liu

As the city develops radiady, the natural gas is widely used nealy in every filed of people’s lives. During the pressure regulation, the phenomenon of ice jam, which can affect the normal utilization, happens. Heater can be regarded as one of the most important measures that prevents pipe from freezing occurring due to temperature drop caused by pressure regulation. Low-temperature radiant heater with tight structure is specifically designed for gad gate station. The heat transfer process of the gate station is analyzed. In the meantime, the mathematical model of radiant heater, which could be fitted for the gate station, is erected. At the same time, the influence of heat exchange size, radiant panel size and radiant efficiency, brought by tube are discussed. The result shows that the tube type of radiant heater has a greatest performance. Considering the tubes with compact structure, taking tube type of radiant heater as the heater used in gate station is the optimal decision. The analysis combined in this paper is the foundation to choose the heater of gate station.

A Novel Slot-Ring Coupling Antenna with Switchable Polarization

Applied Mechanics and Materials (2011)

Shun Gao An Guo Wang Jing Pei Guo Huang Zhao

In this paper, a novel slot-ring coupling antenna with reconfigurable circular polarization is presented. The antenna consists of Wilkinson power divider and a slot-ring with perturbations. By controlling the states of the switches, the antenna can achieve right-hand circular polarization (RHCP), left-hand circular polarization (LHCP) in the same direction, respectively. The proposed antenna is designed and simulated using Ansoft HFSS. The measured results of the fabricated antenna are in good agreement with the simulated. Both measured and simulated results of the antenna are presented and discussed.
