Hardcover. Etat : new. Hardcover. This book investigates in detail the generalized principle of the pattern multiplication (GPPM) and its application to new phased array with high performances. It introduces the generalized element factor (GEF) to small aperture with multi-modes. Based on the GEF, the GPPM can be used to construct the wide-angle scanning array with the dual-port phase mode antenna. Further, a dual-port phase mode SSPPs antenna is proposed to scan in 3D free space. It is extended to two kinds of 1D arrays with 4 elements; both of them perform good 3D scanning with high gain and large range, which will improve future radar design and wireless communication. This book proposes a new method to develop the potentialities of the GPPM and the new phase array. And the readers can study the method or ideas of the GEF, GPPM, even graft the methods to new phase mode antenna and array. It is intended for undergraduate and graduate students who are interested in new phase mode antenna and array technology, researchers investigating high-performance antenna, and antenna design engineers working on phase array applications.

Taschenbuch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - Omnidirectional antenna with high gain, low profile, vertical polarization, even CP polarization is very difficult to design, although it is from the dipole. In this book, a novel idea that the running wave in the coaxial wire is disturbed by the orthogonal slot array on the cylindrical metal shell is introduced, which radiates the CP wave in omni-direction.When feeding on two ends of the coaxial wire respectively, there will appear left hand circularly polarized (LHCP) omnidirectional radiation or right hand circularly polarized (RHCP) omnidirectional radiation. By introducing the T-shaped feed structure, the coaxial wire with slot array can conveniently produce the LHCP and RHCP radiation diversity with one end feeding. In the further, combining with the directional antenna, it will generate the pattern diversity in the half-sphere space.The antenna of the coaxial wire with slot array can further transform into conical CP beam antenna if the coaxial wire becomes into a conical frustum. By introducing the PIN diode into the slot, the antenna of the coaxial wire with slot array can radiate the reconfigurable directional beam by switching the states of the PIN diodes. By introducing a novel switchable microwave circuit, the omnidirectional /directional pattern switchable antenna can be realized easily.This book proposes a continues method to develop the potentialities of the omnidirectional antenna. And the readers can study the method or ideas of the omnidirectional slots antenna, even graft the CP or diversity methods to other antennae.…
