Beam-scanning SIW antennas based on association of various shaped slots | IEEE Conference Publication | IEEE Xplore
This paper presents a new switched beam antenna array working at 26GHz for future 5G application, based on the sub-arrays containing an association of various shaped slot (L, U, S) engraved in Substrate Integrated Waveguide (SIW). The phase shift between each slot is obtained by adjusting the position of transversal slots. The beam tilt is obtained by choosing the adequate slots combination. Finally SPDT switches can be used to control the antenna beam in 8 different directions between -46° and 46° in the same plane or to combine different sub-arrays to carry out multi-beams antenna array. Results of simulations (CST Microwave) are given and validate the proposed solution.

Comparative Study, Design and Performance Analysis of Wide Slot Antenna with Patch-Feed for Bandwidth Enhancement | PDF
This document presents the design and simulation of a triangular wide slot antenna with a triangular patch feed. The antenna achieves an impedance bandwidth of 116% from 2.1 GHz to 7.9 GHz. Various parameters of the antenna design were analyzed through simulation to understand their impact on bandwidth, including patch length and width, feed gap width, and waveguide width. Sensitivity analysis showed that a patch length and width of 15 mm, feed gap of 2.5 mm, and waveguide width of 0.7 mm produced an optimized performance with stable radiation patterns across the operating band. The antenna demonstrates potential for applications requiring wide bandwidth such as WLAN, Wi-Fi, and WiMAX. - Download as a PDF or view online for free
