Abstract
A millimetre wave multi-polarised microstrip antenna array based on linearly polarised subarrays and its applications are presented. The theoretical analysis of the far-zone electric field of the antenna array is also presented, which indicates that the polarisation of the far-zone electric field can be configured by adjusting the feed amplitude and phase of each subarray. The measured results show that the beamwidth of the cross-polarisation level less than -15 dB varies with the location of the field point and the number of subarrays. The millimetre wave multi-polarised microstrip antenna has obvious advantages that the layout and the feed network are simple and easy to be manufactured, which is suitable for millimetre wave miniature radars and detectors.
