Abstract: An antenna apparatus includes first and second antenna elements. The first antenna element operates as a loop antenna that resonates at a first wavelength, and the antenna apparatus operates as an inverted-F antenna that resonates at a second wavelength. The first antenna elements includes a first element portion formed to have a predetermined height from a surface of a dielectric substrate, and the second antenna element includes a second element portion which is formed to be substantially parallel to the first element portion at least at a predetermined distance apart from the first antenna element.

Abstract: A first communication device stores a transmission rate table including response times, and transmission rates associated with the response times, each first response time indicating a time for transmitting test data between the first and second communication devices, while transmitting load data between any pair of communication devices at one of different transmission rates. The first communication device determine a necessary transmission rate for actual data; detect a response time indicating a time for transmitting the test data between the first and second communication devices; determine a transmission rate associated with the response time, as a used transmission rate, based on the transmission rate table; determine an effective remaining transmission rate based on a maximum transmission rate of the communication network and the used transmission rate; and start transmission of the actual data when the effective remaining transmission rate is higher than the necessary transmission rate.
