The conditions for antenna diversity action are investigated. In terms of the fields, a condition
is shown to be that the incident field and the far field of the diversity antenna should obey (or …

The correlation between signals received by two mobile radio base-station antennas is
investigated to determine spacing requirements for space diversity. Measurements of the …

A novel dual-band printed diversity antenna is proposed and studied. The antenna, which
consists of two back-to-back monopoles with symmetric configuration, is printed on a printed …

This paper presents a simple two-branch transmit diversity scheme. Using two transmit
antennas and one receive antenna the scheme provides the same diversity order as …

In a known diversity transmission method, two signals with different identifications are
transmitted via two spaced antennas. To be able to apply the diversity principle to more than …

Using the metric actual diversity gain (ADG), diversity performance is investigated for a
compact mobile terminal prototype with two internal, triple frequency band antennas in four …

The angle diversity performance of two types of high-gain multibeam antennas-24 vertically
polarized 15/spl deg/beams and 12 vertically polarized 30/spl deg/beams-were tested and …

Switched parasitic elements provide a useful implementation of antenna pattern diversity.
The basic principle is presented with some examples of wire antennas computed using the …

Diversity, ie transmitting multiple replicas of a signal, may mitigate fading in wireless
networks. Among other diversity techniques, the space diversity of multi-antenna systems is …

This paper investigates diversity for dual-antenna systems operating in indoor environments.
First, an approximated equation of the diversity gain is derived for different combining …
