Abstract

The wireless communication network system requires complex configuration component of the electromagnetic feeding network circuit, and high-cost material, especially for the electromagnetic component on a high frequency.5.8 GHz with Double 90-degree phase difference output using butler matrix feeding Network for the wireless communication network system. it is the novel shaped and configuration microstrip electromagnetic circuit with the free frequency, no complex configuration, and low-cost material at the 5.8 GHz. This system is package consists of a 5.8 GHz Microstrip antenna with the array rectangular microstrip antenna, and Butler matrix to generate double 90-degree phase difference with quad input and quad output. The Antenna has a single band and narrow bandwidth with the four-port and have a single working frequency that is 5.58 GHz under -10dB S parameter and using via hole for a transmission line to network feeding system, the radiation pattern is directional and the gain level is 6.83 dB and 50 ohms feeding impedance. The 90-degree hybrid coupler has S11 of -26.19 dB, S21 of 31.65 dB, S51 of -26.18 dB, and S61 of -32.52 dB that all is specification has a good working. And overall size of the proposed this configuration is 80 mm times 65 mm with Phenolic White Paper with a dielectric constant is 4.4 that has 50ohm.

Keywords: Microstrip antenna, Butler matrix, Array rectangular microstrip antenna.
