Abstract
This communication proposes a compact 16 GHz / 30 GHz dual band antenna design for Ku / Ka band applications. The antenna consists of two layers with lower layer having the fed patch and the upper layer having non-periodic element array. The antenna has been designed to operate at two different frequencies with compact dimensions of (8mm x 8mm) using Rogers RT 5880. The compact size of this proposed antenna also makes it suitable for integration with the microwave and millimeter wave circuits. The proposed antenna provides high radiation efficiency and a peak gain of about 8 dB at the resonant frequencies with reduced side lobe levels.
Highlights
Microstrip antennas have been widely used in wireless communication systems because they are low profile, light weight, low cost, conformal design, and easy to fabricate and integrate
We have proposed a novel dual band two-layer antenna design especially designed for Ku and Ka-band applications and for integration with microwave and millimeter wave circuits
First the lower structure has been optimized for a slotted rectangular patch and the upper layer structure has been optimized very carefully to obtain dual band characteristics
Summary
Microstrip antennas have been widely used in wireless communication systems because they are low profile, light weight, low cost, conformal design, and easy to fabricate and integrate. Obtaining dual band or multiband characteristics is very useful for many antenna applications especially at higher frequencies With the time these dualband antennas have been improved to face more challenging demands of the modern wireless communication systems that are capable of integrating more than one communication standard into a single system. These antennas are designed to be integrated in different array systems in which they can be operated at a single or multi frequency bands simultaneously [10-16]. The antenna as a whole provides a good solution for high frequency applications with its dual band and good radiation characteristics
