Basic Theory of Omnidirectional Antenna and Slot Array,e is called guided wave. Generally, guided wave system with constant section size, shape, medium distribution, material and boundary conditions is called regular guided wave system, also known as uniform transmission line.

Principles of Omnidirectional Dual-CP Slot Array Antenna,vironment, in which the antenna with dual circular polarization performances, left hand circular polarization (LHCP) or right hand circular polarization (RHCP), is very applicable and valuable in the complicated EM environment.

Dual CP Polarization Diversity and Space Diversity Antennas Enabled by a Compact T-Shaped Feed Stru is not only to transmit or receive signal, but also increase the system performances. Such as polarization diversity (PDA) and spatial diversity (SDA) antennas, has been strong powerful to achieve large cover and high-speed transmission.

The Omnidirectional/Directional Switchable Antenna Based on the Curved Microstrip Antenna with Defee and more users. However, with the digital circuit being packaged into chip, the terminal miniaturization has gone to bottleneck period. The microwave transmission line and antenna is difficult to reduce size, but the RF module and antenna cover more than 80% surface of the terminal and more than 6
