## Abstract In this article, a new slot antenna with a quasiβspiral slot is proposed.A simple microstrip line feed is used to excite the slot antenna. Measurement results show that 10 dB return loss bandwidth and 3 dB axial ratio bandwidth of the proposed antenna are 87 and 43%, respectively. Β© 201
## Abstract Wideband circular polarization with a boresight axial ratio of β€ 2.2 dB is achieved over 35% of bandwidth by sequential rotation of linearly polarized radial stubβfed slot elements (2 Γ 2 array). The effect of the feed interactions upon the antenna radiation pattern is also analysed. Th
