Multi-Function Patch Element

Abstract: Abstract-Integration of multiple functions is for the first time achieved within a single patch circuit element. Firstly, out of phase equal power division and bandpass filter characteristics are combined within a patch element. The novelty of the proposed structure is to use simple asymmetric cross slots in the patch element to achieve this integration. A simplified equivalent circuit model to describe operation of this patch element is proposed. Coplanar waveguide/microstrip broadside coupling is then invest… Show more

“…In the designs of microstrip BPFs, dual-mode resonators with ring, loop and patch structures are more attractive because of their half-reduced number of resonators and compact filter configurations, compared with single-mode resonators [4][5][6][7][8][9][10][11][12][13]. The BPFs designed by using dual-mode patch resonators show higher power-handling capability than those using ring or loop resonators [8][9][10][11][12][13]. Lots of effort has been done for tunable single-mode patch resonators [3] and for dual-mode ring or loop resonators [4][5][6].…”

“…Circuit integration is a straightforward approach in resolving the above problems with the concept already demonstrated with balun filters [16][17][18][19][20] which combine out of phase power division with bandpass filtering function. The coupler filter proposed by Uysal and Watkins [21,22], made by non-uniform transmission lines had a relative bandwidth of 18% but occupied an area of more than 2-wavelengths by 5-wavelengths at the center frequency.…”
