A COMPACT LOW PROFILE INVERTED-F MULTI BAND ANTENNA (IFMBA) SYSTEM FOR WIFI – WLAN - WIMAX APPLICATIONS

We present in this paper a compact low profile inverted-F Multi band antenna (IFMBA) system with MIMO feature for WiFi – WLAN - WiMAX applications. The proposed antenna IFMBA suits for 2.4, 3.5 & 5 GHz operations in multi-path propagating environments with capability to reduce the deep fading caused. It has a smart feature of low profile, near omni directional patterns and placed on printed circuit diplexer feed network of compact size for multiband operation. This antenna is useful for indoor small cell base station applications with support for polarization diversity / spatial diversity. Presented in this paper here is the IFMBA with simulated results, prototyped and results from measurement, from which it is evident that the measured results are in close agreement with that of simulated. The targeted 10 dB return loss bandwidth is achieved and its near omni directional radiation patterns are validated by experimental measurements
