Abstract
A surface mounting antenna in which easy formation of a radiation electrode can be achieved by forming it on the surface of a substrate, and also the antenna can be downsized by bending the radiation electrode. A communication apparatus using the above antenna is also disclosed. A ground terminal and a feeding terminal are separately disposed on one lateral surface. A loading capacitor electrode is formed on another lateral surface opposedly facing the surface on which the ground terminal and the feeding terminal are disposed. A stripline radiation electrode is further formed on the obverse surface of the substrate and is connected at the respective ends to the ground terminal and the loading capacitor electrode. A feeding electrode for connecting the matching portion of the radiation electrode and the feeding terminal is disposed on the obverse surface of the substrate.
