Speech Title: Multifunction antennas constituted by delicate structures
Abstract: Multifunction antennas, which can be realized just within the volume of one conventional antenna, are introduced. The antennas are investigated to meet the demand of the multifunction electronic systems in a compact volume, which can work as radar and communication simultaneously or work in multi-bands and different polarizations. The multifunction antennas are constituted by delicate structures. Simulation and experimental results are presented to show the performance.
The demands for multifunction electronic systems in a compact volume, which can work as radar and communication simultaneously or work in multi-bands and different polarizations, are increasing. This demands multifunction antenna to be realized just within the volume of one conventional antenna. This paper introduces our work on the multifunction antennas as follows.
1. Dual frequency bands waveguide slots antenna by sharing common aperture. Two waveguide slot antennas with same polarization that work in millimeter wave band and microwave band respectively are realized within one conventional antenna aperture by delicate architecture. The simulation and experimental results are presented to show the performance of the antenna.
2. Above technique is used to realize a dual frequency dual polarization waveguide slot antenna. The simulation are presented to show the performance of the antenna.
3. A multifunction antenna was composed by a waveguide slot antenna and a microstrip array antenna and realized within one conventional antenna aperture. Microstrip array antenna is dual polarization, which is put on the upper surface of the waveguide slot antenna and its layout must be careful not to cover the waveguide slot or affect the radiation property of the waveguide slot. Waveguide slot antenna works at Ka band, microstrip dual polarization antenna works at microwave band. Waveguide slot has been designed have good performance; its slot position cannot be changed. So the microstrip dual polarization antenna can only be placed in the place where there are no waveguide slot. Simulation results are presented.
Key words: microwaves, millimeter waves, multifunction antennas
