Antenna measurements such as VSWR were measured with an Agilent E5071C Vector Network Analyzer. Radiation patterns were measured
with an Agilent 5181A Signal Generator and Agilent E4445A Spectrum Analyzer in a three-meter anechoic chamber.
Flat surface measurements were done with the antenna centered on a 1.5-millimeter thick plate of Polycarbonate.
