In this thesis, we utilize the bond wire for compensation on the input impedance matching of buried circuits. With proper design, the module has compact size, omni-directional radiation pattern, and low insertion loss of passive circuits. The proposed antenna switch module is suitable for applications of IEEE 802.11a WLAN.
