ABSTRACT:
The present invention provides a method, dual rectangular patch antenna system, and radio for providing isolation and diversity while eliminating the need for a diplexer or a second transmit/receive switch. The dual rectangular patch antenna system comprises a first rectangular patch antenna (202), a second rectangular patch antenna (204), and a switch (206). Receive path diversity is provided by switching between the first rectangular patch antenna (202) and the second rectangular patch antenna (204).
