Platinum band planar antenna with quintuple collinear structure

摘要

A platinum band (815 MHz to 960 MHz) planar antenna with a quintuple collinear structure is proposed, calculated and examined in order to improve maximum and average values of the absolute gains. The calculated values of the return losses agree very well with the measured ones in the frequency bands. Also, from the measured results of the radiation patterns, the maximum and average values of the absolute gains for the prototype antenna are high enough to be commercialized to a platinum band.
