radiation pattern of the antenna. II. ANTENNA DESIGN AND OPERATION A. Annular slot antenna in DC operating mode Monopole antenna has been the subject of many classic studies for diversity in radiation pattern of an antenna. A monopole antenna has an omnidirectional radiation pattern which is essential for wide range of technologies. The A Broadband Pattern Diversity Annular Slot Antenna An annular slot antenna suitable for pattern diversity in wideband applications is presented. Pattern diversity is obtained by feeding the antenna simultaneously with two microstrip lines printed ... A Broadband Pattern Diversity Annular Slot Antenna An annular slot antenna suitable for pattern diversity in wideband applications is presented. Pattern diversity is obtained by feeding the antenna simultaneously with two microstrip lines printed on the back of the substrate, which generate orthogonal radiation patterns. Four Ports Wideband Pattern Diversity MIMO Antenna
3.4.2 Multi-port annular ring slot antenna (M-ARSA)
Directional Antenna Diversity for Mobile Devices First, the RSSI pattern of a directional antenna may significantly deviate from the antenna gain pattern. This is especially true in NLOS environments.Also, all the antenna selection algorithms for receiver diversity systems are intended for the receiver side, which makes them different from MiDAS.
