Abstract


One of the huge developments of wireless technology is WiMAX technology utilizing coplanar waveguide feed for Wireless Local Area Network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) frequency bands are presented. The proposed antenna is fabricated on Aluminum Nitride Ceramic substrate with dielectric constant 4.6 and thickness of small mm.  Antenna is one of the most important components in wireless communication. Due to the presence of different frequency bands of WiMAX used everywhere; there is a need to develop an antenna that has the flexibility for this provision. This paper discusses the design of coplanar waveguide in wideband microstrip antenna. The antenna microstrip design uses different substrate with different dielectric constant. The dimension of antenna can be seen that the antenna design proposed by the author has a wide bandwidth that includes different frequency band. The antenna gain falls between 1.8 – 2 dBi with unidirectional radiation pattern.
