With increasing complexity of microwave integrated circuits and tendency towards building integrated modules, real estate in printed circuit boards becomes more at premium. On the other hand, building MIC's on a single semiconductor substrate such as GaAs has other drawbacks as substrate requirements for different components are sometimes contradictory. This has motivated researchers to consider multi-layer and stacked designs. Multi-layer planar circuits offer advantages that cannot be equalled by traditional single layer designs. In this respect, a new class of planar structures, based upon a multi-layered stack of dual-mode stripline or microstrip patches is becoming increasingly popular. In the new stacked design, coupling between planar circuits separated by a ground plane is accomplished through coupling apertures in the common ground plane.This thesis is about developing an new approximate multiport network model for fast analysis of multi-layered planar structures with ground plane slots. To extend applicability of multiport network model (MNM) to the class of planar structures containing ground plane slots, a generalized network formulation for aperture problems is combined with traditional MNM to account for the presence of the slot. To this end, the slot is replaced by an unknown equivalent surface magnetic current. Slot ports are defined in terms of electric and magnetic fields over the slot in accordance with the generalized network formulation for aperture problems. While traditional MNM for planar circuits is based on generalized impedance matrices, we adopt a hybrid matrix approach for multi-layer structures. The hybrid matrix consists of four sub-matrices that relate terminal voltages and currents of edge and slot ports. The same generalized impedance matrix in the absence of the slot can be used to relate terminal voltages and currents of edge ports when the slot ports are short-circuited. Open circuit voltage at edge ports due to terminal voltages at slot ports and terminal currents at slot ports due to input currents at edge ports are represented by two transfer matrices. Both these transfer matrices can be calculated from 2D analysis which only considers T M z modes.Interaction among slot ports, represented by a generalized admittance matrix, however, requires considering both T M z and T E z modes. This generalized admittance matrix is obtained from tangential component of the magnetic field over the slot due to the equivalent surface magnetic current and relates terminal voltages and currents of slot ports. Full modal expansion consisting of both T M z and T E z modes is used to compute the generalized admittance matrix of a slot in a regularly shaped planar cavity. For irregularly shaped patches, modal expansion is not available. Instead, a new contour integral equation for magnetic field, derived for the iii first time in this thesis, is combined with complex images method for calculation of generalized admittance matrix of a slot radiating in a planar cavity of arbitrary shape.O...

“…Instead of the aperturecoupled patch elements, two-port aperture-coupled stacked-patch (ASP) antennas have been designed as the array elements and the conventional ASP antenna [21] is applied as the radiating matched load. The double-resonance property of the aperture-coupled stackedpatch maintains in the two-port form, which improves the pattern bandwidth and offers the array a better tolerance to the fabrication errors.…”

Abstract-A shaped-beam series-fed aperture-coupled stacked patch array antenna at X-band is presented.To improve the array bandwidth, two-port aperture-coupled stacked patch antennas, which are suitable for the series-fed array configuration, are presented as the radiating elements. To offer the pattern design and optimization progresses more flexibility, a uniformly spaced array configuration is applied in the shaped-beam pattern design, instead of the conventional nonuniformly spaced array configuration. The experimental results show that, in a 7.6% bandwidth, the main beam shape of the array maintains in good agreement with the design goal, and the side lobe level maintains lower than −18 dB.
