Abstract: A capacitive touch panel has multiple electrode couples formed on a substrate. Each electrode couple has multiple first electrodes and multiple second electrodes. Each of the first electrode and the second electrode has three traces. Each end of one of the three traces is connected to one end of one of the other two traces. The three traces of the first electrode and the three traces of the second electrode are alternately arranged. Given the foregoing layout of the electrode couples, the first electrodes and the second electrodes have symmetrical capacitance values and resistance values. Accordingly, the capacitive touch panel has an enhance signal-to-noise ratio and an anti-interference capability.

Abstract: The present invention is to provide a dynamic power control circuit for a wireless communication device, which comprises a power detector, a comparator, a low pass filter and an adder disposed between a radio frequency auto-gain control circuit and an antenna thereof. A reference voltage is imposed on the adder to enable the power detector to detect and output signal voltage to the comparator which compares the received voltage with a specified received voltage limit and outputs a reference voltage to the low pass filter for filtering out the noise of the reference voltage and outputting it to the adder. The adder then adds the reference voltage and the specified reference voltage, and outputs the result to the radio frequency auto-gain control circuit for controlling the output power corresponding to the strength of the received signals.

Abstract: The present invention is to provide a combination antenna having multi-mode and multi-band arrangements, which comprises a conductive seat; a non-uniform helical antenna extending from one end of the conductive seat; and a pole antenna extending from one end of the conductive seat through the helical antenna, enabling to be tuned to three or more resonant frequencies through tuning the helical antenna to a plurality of resonant frequencies and tuning the pole antenna to a plurality of resonant frequencies different from that to which the helical antenna is tuned.
