Miniaturized low-profile filtering omnidirectional antenna design

Dianzi Jishu Yingyong
A miniaturized omnidirectional microstrip filter antenna is designed. The antenna is composed of a bandpass filter and a microstrip antenna, which share a ground plane to reduce the size and are connected by gap coupling. The bandpass filter is etched at

Omnidirectional circularly-polarised microstrip patch antenna

Electronics Letters, 2012
An omnidirectional circularly-polarised patch antenna is proposed. The antenna radiates right-handed circular-polarisation with an average axial ratio of 2.3dB over a full 360°. A shallow diagonal CPW inset-feed was used to achieve good matching to the back-to-back coupled patches, providing a measured S 11<-15dB at the centre frequency.

Pattern reconfigurable back‐to‐back microstrip patch antenna

IET Microwaves, Antennas & Propagation, 2016
A back‐to‐back microstrip patch antenna with a switchable pattern is proposed for WLAN applications. The patch elements, printed on FR‐4 substrates with a common ground plane, are switched with a single‐pole double‐throw PIN diode circuit. Switching the feed selects either of two identical radiation patterns in the opposing hemispheres for spatial ...
