Abstract
Official abstract text for this publication.
Disclosed are to a communication terminal and an antenna apparatus thereof. The antenna apparatus includes an antenna device including a feeding point to which a signal is applied; and at least one variable reactance device connected to the antenna device. The communication terminal determines a communication network to access to drive the antenna apparatus corresponding to the determined communication network, and accesses to the determined communication network through the antenna apparatus to communicate. Accordingly, a resonance frequency band of the antenna apparatus is expanded.
First claim
