A hybrid structure consisting of a printed cross dipole and annular ring antennas with a pattern and polarisation diversity for a four-channel multiple input multiple output system operating in a wireless local area network (LAN) (2.34-2.54 GHz) is presented. The entire antenna size is only 88 ?? 88 ?? 44 mm. The envelope correlation coefficient and mean effective gain are computed using measured...
Proposed is a novel way of inserting a propagation stop frequency band for dual-band operation of a leaky wave antenna (LWA). To make the LWA resonate at two frequencies, the stopband is introduced into an existing passband, which induces two specific conditions giving maximum radiation towards a boresight direction at the resonant frequencies locating on both sides of the stopband edge. All experiment...
