Abstract
AbstractIn this letter, a planar cavity‐backed multiplexing antenna (SMA) is proposed and validated experimentally. A planar cavity is realized by using a novel transmission line known as substrate‐integrated waveguide (SIW) technology. The design comprises five SIW cavities and each one consisting of a slot for launching the energy in free space. Three different types of slots are employed for lower mutual coupling and compact circuit integration. The individual feeds are created in such a way, that antenna produces five distinct resonant frequencies in the dominant mode while maintaining sufficient mutual port isolation. Finally, the proposed concept is validated with experiments and results show acceptable agreement with the simulated counterparts. The design shows five operating frequency channels with center frequencies of 5.2, 5.5, 5.75, 6.2, and 6.8 GHz. The mutual isolation between any two radiating elements retains below −21 dB and the average gain of the antenna is better than 3.5 dBi at each resonant frequency. The proposed SMA element can be used to cover a wide range of wireless access points and seems suitable for multiple wireless system integration.
