摘要： In the sector antenna of the present invention, a feeder waveguide is formed that branches midway from a feeder port to each of a plurality of antennas. This feeder waveguide is formed from a waveguide tube and includes a main feeder line that extends from a waveguide that extends from the feeder port and branches in two directions, and branch feeder lines that each branch in two directions from the two ends of the main feeder line.

摘要： To reduce time to point a directional wireless portable terminal (WPT) to an access point (AP) when data is downloaded from the AP to the WPT, a user points the WPT to the AP, performs a first operation and transmits a request of authentication and download to the AP. The AP requests a server to perform the authentication and the download. The server transmits information on a current situation to the AP. The AP calculates time required until the download can be started based on content capacity and the like and transmits information on the calculated time to the WPT. The WPT displays countdown until the download can be started. During that time, the server performs the authentication and, if successful, delivers content to the AP. When the download can begin, the user performs a second operation and transmits a request of re-authentication and download to the AP.

摘要： A bit error rate of the reception signal is detected on the reception side, such that an n optimal modulation method and LO output power are determined in accordance with this bit error rate, and an LO output changing instruction is sent to an image signal rejection mixer on the transmission side. The image signal rejection mixer changes the phase X=α+γ in response to the LO output changing instruction when power splitter (201) splits the LO into two components with equal amplitude and phase difference α, power splitter (202) splits the IF signal into two components with equal amplitude and phase difference β, and power combiner (205) combines RF signals with equal amplitude and phase difference γ. By changing the X, the LO output power is controlled and the back-off amount of a transmission amplifier is changed in accordance with an optimal modulation scheme. In this event, α−β+γ=2nπ (n is an integer) is set so as to maximize the image signal rejection amount.
