Abstract As more components populate smaller board areas, the risk of unwanted coupling between components increases. Shielding and radiated emissions tests outlined by IEEE standards such as IEC 61000-4-21 and ASTM4935D identify measurement techniques to quantify shielding effectiveness. In a PCB topology, shields enclose components to create a Faraday cage, but necessitate a method to ground and fasten the shield to the PCB. Typical methods include the use of gaskets, sealants and clips. This paper reviews a gasket methodology and validates a parameterized ANSYS HFSS simulation with the meas

Abstract:

For calibrating the X-band equipment in the TT&C ship based on wireless communication, we design a high gain rectangular horn antenna. Through analysing the theory of structure, the antenna’s preliminary size parameter is estimated and it is simulated based on HFSS. The antenna structure parameters are obtained after parameters optimization. The results of simulation indicate that the design of antenna indexes meet the needs completely. The structure of antenna is compact and it easy to process. The simulation method in the paper may also be referred to other related design.

This letter presents a Ka-band(26.5GHz-40GHz) microstrip patch antenna with pattern reconfigurable characteristic. The antenna is provided with five rectangular patches and four RF MEMS (microelectromechanical systems for RF circuits) switches. The central patch and other surrounding patches are connected by the switches. By changing the states of the switches, the antenna can achieve four radiation patterns and it is designed and simulated by using Ansoft HFSS. In addition, the different states are operated at the same centre frequency of 35GHz and the gain of the main radiation direction is

Abstract:

In this paper, a novel design for planar plate monopole antennas is proposed with applications to ultra-wide band (UWB) communications. To verify the proposed antenna design, simulations are performed by means of CST and HFSS software tools, showing that the impedance bandwidth is significantly increased by vertical cross-sections. By adding a series of parameters to the vertical cross sections, the antenna efficiency is effectively enhanced by achieving a return loss of 10 dB over the bandwidth range between 3.1 GHz and 10.6 GHz. In addition, our experimental results demonstrate that the fabr

Firstly, the development and principle of PIFA antenna in mobile phone are introduced, and the typical PIFA antenna design is analyzed. The PIFA antenna simulation is based on HFSS software. It is found that the high frequency bandwidth of this kind of antenna is very narrow. Then related parameters are optimized, by increasing the parasitic branch in high frequency band. Simulation results show that the return loss of PIFA antenna in high band is improved and the antenna can be expanded in high band, and matched in low band simultaneously.
