A novel antenna reconfiguration mechanism based on the displacement of liquid metal
sections is presented. The liquid nature of the moving parts of the antenna helps avoid the …

A millimeter-wave frequency scanning antenna, which is capable of dynamically changing
the state of polarization thereby providing four modes of operation, is investigated and …

This book throws a lifeline to designers wading through mounds of antenna array patents
looking for the most suitable systems for their projects. Drastically reducing the research time …

Wireless fidelity (WiFi) is a superset of the IEEE 802.11 standards for communications over
several tens of meters. A WiFi device connects to the network via an access point. The …

A 2× 2 array with pattern and polarization diversities is presented. The radiating element of
the array is a stacked annular-ring microstrip antenna where four pin diodes are …

An investigation of novel techniques in the designing of a low profile, horizontally polarized
omnidirectional (HPO) patch antenna with omnidirectionality in the H-plane using a defected …

A novel, horizontally polarized, conical-beam antenna is proposed. The antenna is low in
profile (H= 0.1867 lambda o) and has about 38% impedance bandwidth (SWR< 2) and …

A four-port wideband diversity antenna capable of radiating two broadside patterns and two
omnidirectional patterns is realized. This antenna is composed of five dual-polarized …

An antenna that is capable of exciting four different kinds of linearly polarized waves by four
independent feeding ports across an overlapped frequency band is presented. The four …

A design method is described for reconfigurable circularly-polarized (CP) microstrip array
antennas with conical-beam radiation. The proposed antenna structure consists of four L …
