    摘要: The present invention is an antenna apparatus attached to an electronic device and includes an antenna section (11) having an antenna element (18) provided with two or more power supply points (19) and two or more earth points (20); and an earth point switch (21) which is provided correspondingly to each earth point (20) and connects or disconnects the earth point (20) from a ground. Selectively turning on or off the earth point switch (21) selects the earth point to adjust the resonance frequency.

    摘要: The present invention provides a small, thin filter circuit showing a desired filter characteristic which is highly accurate, and producible with a high efficiency. The filter circuit includes a pair of dielectric insulating layers 2 and 3, upper and lower, each having a ground pattern 11 (16) formed on the main side thereof, and an inner wiring layer 4 formed between the dielectric insulating layers 2 and 3 and having capacitively coupled resonator conductive patterns 6 and 7 each connected at one end thereof to the ground patterns 11 and 16 via inter-layer connecting vias 12 and open-circuited at the other end. The filter circuit has formed on the inner wiring layer 4 thereof a plurality of capacitive load patterns 8 to 10 laid along the peripheries of the open-circuited end of the resonator conductive patterns 6 and 7 and electrically isolated from the ground pattern 16, and on one of the dielectric insulating layers 2 and 3 thereof correspondingly to each of the capacitive load patterns 8 to 10 a plurality of capacitive load adjusting patterns 17 to 19 electrically isolated from the ground patterns, electrically connected by the inter-layer connecting vias 24 to 26 to each other, and selectively connected to the ground pattern 16.
