Integrated laptop antennas - Design and evaluation

Two performance parameters are used to define integrated antennas for laptop applications. One is SWR, and the other is the average antenna gain. Based upon link budget models and system requirements, the integrated antennas should be at a 2:1 SWR bandwidth, wide enough to cover the 2.4 GHz ISM band to ensure a wireless system with reliable, high data rate performance over a useful range or coverage area.
