Design of Rotman Lens Antenna at Ku-Band Based on Substrate Integrated Technology

Ku-band Reconfigurable MEMS Antenna on Silicon substrate

This article presents design and fabrication methodology of Ku Band (linearly polarized) reconfigurable patch antenna. Both bulk and surface micromaching techniques are implemented on patch to have better RF performances. Reconfigurability is implemented by integrating shunt capacitive switch with microstrip patch antenna. Effect of feed mechanisms and role of micromachining on antenna paramete...

Design of a Modified W-shaped Patch Antenna on Al2o3 Ceramic Material Substrate for Ku-band

An influx of research has been devoted to use different di-electric substrate materials for antenna miniaturization. Design of A modified W-shaped ka band antenna on Al2O3 ceramic substrate is presented in this paper. The W shape is obtained from slotted conventional rectangular shaped patch. The ceramic substrate made with Aluminum oxide (Al2O3) with high dielectric constant and 1.5 mm thickne...

Design, simulation and Fabrication of Circularly Polarized Fabry-Perot Antenna for Ku Band

This paper deals with the design and simulation of a RHCP Fabry-Perot antenna for 14.5 GHz. Based on transmission line model, partially Reflecting Surface (PRS) was designed so thatgain enhancement and circular polarization simultaneously obtained. PRS consist of a square loop and meander-line at the top and bottom respectively. In order to achieve the resonance condition in orthogonal componen...

Design Investigation of Microstrip Patch and Half-Mode Substrate Integrated Waveguide Cavity Hybrid Antenna Arrays

In this paper two linear arrays including a linear 1×4 and a planar 2×2 of microstrip patch and half-mode substrate integrated waveguide (SIW) cavity hybrid antenna are introduced and investigated. These are simply implemented using low cost single layer printed circuit board (PCB) process. The array element consists of a rectangular microstrip patch with appropriate dimensions in the vicinity ...
