TRANSMISSION/RECEPTION ANTENNA AND TRANSMITTER RECEIVER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a transmission/reception antenna and transmitter receiver using the same, capable of band widening of frequency characteristics and reduction in power consumption.

SOLUTION: The transmission/reception antenna includes: a dielectric substrate 11; a loop antenna 12 for excitation mounted on the dielectric substrate 11; a connection terminal 13 for transmission processing part connected to the loop antenna 12 for excitation; a loop antenna 14 for transmission and reception disposed in proximity to the loop antenna 12 for excitation in a contactless state; a capacitor 15 for resonance connected to both ends of the loop antenna 14 for transmission and reception; and a connection terminal 16 for reception processing part connected to the loop antenna 14 for transmission and reception. The loop antenna 12 for excitation has a one-turn loop.
