摘要： The antenna comprises a metal excitation loop (B1) to be positioned at a height (h) of at least about 1 above the surface (SM) of a conducting medium (M) and a supply means (A, L1n) to be connected to the conducting medium. The perimeter of the loop is about one half of the operating wavelength, namely λ/2, in length. The loop comprises two approximately parallel portions (I1p-I1n, S1) which are at most about λ/50 apart and are capable of extending approximately parallel to said surface in a plane approximately perpendicular to said surface, currents of opposite direction flowing through said portions. The closest portion to said surface includes an aperture between ends (E1p, E1n) of the loop that are connected to the supply means. The antenna is better protected from space waves and it can be reduced in size by being folded up.

摘要： To broadcast synchronized radio waves in at least one frequency band in a predetermined territory, antennas (AS, ATI, AE) emit waves to respective coverage areas in which receivers (RQ, RB) measure characteristics of the emitted waves and transmit to a central server (SC) . The server analyzes the characteristics (CO) as a function of prediction models for broadcasting waves in the territory in order to determine adjustment parameters for the antennas. The server transmits the adjustment parameters to the antennas to control them in order to offer a greater diversity of radio broadcasting services and to optimize coverage areas according to different wave propagation modes.
摘要翻译： 为了在预定区域中的至少一个频带中广播同步的无线电波，天线（AS，ATI，AE）向接收机（RQ，RB）测量发射波的特性并发送到中央服务器的各个覆盖区域发射波 （SC）。 服务器将特征（CO）作为区域广播波预测模型的函数进行分析，以确定天线的调整参数。 服务器将调整参数发送到天线以进行控制，以便提供更多的无线电广播服务，并根据不同的波传播模式优化覆盖区域。
