Abstract

A small monopole antenna with novel impedance matching structure is proposed in this paper. The proposed antenna is designed for W-LAN (IEEE 802.11b). The antenna design concept is based on lambda/8 folded monopole antenna with self-impedance matching structure. The size if the proposed antenna is smaller than the resonant length, thus the impedance at the terminal of the antenna becomes very capacitive. To compensate the impedance miss-matching, the proposed antenna employed a novel self-impedance matching structure. The self-impedance matching structure is located on the top of antenna; it improves the impedance matching and ultimately the efficiency of antenna
