摘要：
There is a problem in normal meander line antenna (MLA) that it is difficult to get performances of miniaturization, high efficiency and high inductance at the same time. A simple novel antenna design for this challenge is described. Two capacitive loads are added at the end of MLA to adjust the impendence. For saving material, holes are digged on the loads. Simulation by HFSS shows that, comparing with the regular MLA, the proposed antenna's impedance enhances from 10-12j to 23+150j, and the maximum gain enhances from 1.31dB to 1.67dB, with a read range of 10.1m. Meanwhile the return loss at 915MHz is -34dB, with a wide -10dB bandwidth of 860 similar to 985 MHz.
