According to the simulation with high-frequency structure simulation software (HFSS) and the experimental result, we can get the electromagnetic wave shielding characteristics in GSM (900MHz and 1800MHz) and wireless regional frequency band of network (2.4GHz), according to the structure of geometry and material qualitative change of the aluminium honeycomb and thickness, the conductivity and layers of indium tin oxide (ITO) film and the slot on metal plate.

In addition, this thesis also proposes the design of the small-scale standing wave slot array antenna in process of studying the characteristic of electromagnetic wave radation with slot numbers, angle and cutting depth on the rectangle waveguide. Its structure includes a waveguide carved the slot on the narrow side and two rectangle metal slices on the up and low side. The centre frequency of the antenna is 9.375GHz.It has narrow horizontal radiation angles (smaller than 2°) and gain above 28dB. Its frequency bandwidth can reach 400MHz. It can use not only as wireless directional communication remotely but also as small-scale area search radar. Su,Wen-Quan 蘇文寬 2007 學位論文 ; thesis 97 zh-TW |

碩士 === 國防大學中正理工學院 === 電子工程研究所 === 96 === This thesis illustrates the characteristics of electromagnetic wave radation and the design of shielding structure with various kind of holes on electromagnetic shielding body. According to the simulation with high-frequency structure simulation software (HFSS) and the experimental result, we can get the electromagnetic wave shielding
characteristics in GSM (900MHz and 1800MHz) and wireless regional frequency band of network (2.4GHz), according to the structure of geometry and material qualitative change of the aluminium honeycomb and thickness, the conductivity and layers of indium tin oxide (ITO) film and the slot on metal plate. It can protect people and precision instrument from electromagnetic wave damage and interference under the
situation which doesn’t affect the ventilation, daylighting, space, appearance and cost of building and portable vehicle.
In addition, this thesis also proposes the design of the small-scale standing wave slot array antenna in process of studying the characteristic of electromagnetic wave radation with slot numbers, angle and cutting depth on the rectangle waveguide.
