A planar millimeter-wave shared-aperture array antenna is proposed and designed in this paper. By composing the substrate integrated waveguide (SIW) and the stripline, the K-band antenna is embedded inside the Ka-band antenna to achieve a smaller size and a low profile by sharing an aperture. The Ka-band antenna radiates through the parallel slot pairs on the surface of the SIW cavities with horizontal polarization, while the K-band antenna radiates through the butterfly-shaped slots with vertical polarization, which are also designed on the surface. Then the two array antennas can radiate by sharing a common aperture with high isolation. To verify this idea, a prototype of an 8×8 shared-aperture array antenna has been designed with center frequencies of 19 and 30 GHz and fabricated using multilayer printed circuit board (PCB) technology. The measurement results show that the −10 dB impedance bandwidths in the K- and Ka-bands are 7.73% and >20%, and the corresponding isolations are higher than 60 and 44 dB, respectively. The proposed shared-aperture antenna has a small footprint, a low profile, and high isolation, and is a promising candidate to design compact millimeterwave wireless systems.

Reconfigurable antennas are becoming a major antenna technology for future wireless communications and sensing systems. It is known that, with a single linear polarization (LP) reconfigurable antenna element, a preferred polarization can be produced from a set of multiple polarization states, thus improving the quality of the communication link. This paper presents a new concept of a polarization programmable reconfigurable antenna array that consists of a number of polarization reconfigurable antenna elements with a finite number of possible polarization states. By employing a new optimization strategy and programming the polarization states of all the array elements, we demonstrate that it is possible to realize any desired LP in the vectorial array radiation pattern with accurate control of sidelobe and crosspolarization levels (XPLs), thereby achieving the desired polarization to perfectly match that of the required communications signal. Both numerical and experimental results are provided to prove the concept, and they agree well with each other.

A novel wideband ring antenna for polarization/pattern diversity Correspondence

We present a novel wideband ring antenna for polarization/pattern diversity. The proposed antenna consists of eight printed dipole elements in the form of a circular array. The arms of adjacent elements overlap for capacitive loading. Unlike traditional circular arrays, a method of exciting elements in the form of every two intervals is first introduced. We prove that this method can maintain the wideband characteristics of the antenna. Four independent feeding ports in a ring antenna aperture are designed for the polarization/pattern diversity with suitable feeding networks. As an example, a wideband dual-polarized antenna was designed based on the proposed ring antenna. To achieve two orthogonal linear polarizations with maximum radiation in the direction, two adjacent elements are extracted periodically to feed through one port. The differential feeding network and integrated Baluns have been designed to realize broadside radiation patterns, considering impedance and phase matching. Because the proposed antenna is hollow, it is a good candidate for a multiband sharing aperture antenna element. Results show that the proposed antenna has an overlapped bandwidth of 50.5% (1.04–1.82 GHz) with voltage standing wave ratio (VSWR)<2 for the two polarizations, and port isolation less than 23 dB. The measured realized gain ranges from 6.1 to 8.1 dBi, with stable broadside radiation patterns over the operating frequency band.

Based on the electromagnetic model for four-port resonant filter, the optical characteristics of several filters with rectangular cascade resonators have been numerically simulated by utilizing two-dimensional FDTD method. The relationship between the number of cascade resonators and the filtering features is analyzed. The narrow-band filter with four cascade resonators implemented on GaAlAs/GaAs planar waveguide is designed and fabricated. The experiment result shows the half-width of filtering spectrum for the chip is about 10 nm, which coincides well with that of the simulation.
