This paper presents a slotted-rectangular patch antenna with proximity-coupled feed operated at dual band of millimeter-wave (mmV) frequencies, 28GHz and 38GHz. The antenna was built in multilayer substrate construct by 10-layers Low temperature Co-fiber Ceramic (LTCC) with 5 mils thickness each. The slotted-patch and thick substrate are configured to enhance the bandwidth and obtain a good result...
This paper presents an aperture-coupled microstrip antenna, which is operating at dual band of millimeter-wave (mmW) frequencies, 28GHz and 38GHz. The aperture antenna was integrated with multilayer substrate construct on 5-layers Low temperature Co-fiber Ceramic (LTCC) with 5 mils thickness. The driven patch was applied to enhance the bandwidth. The bandwidths using are 9.1 percent at 28GHz and 9...
In this paper, a design of patch array antenna for WiMAX (Worldwide Interoperability Mobile Access) and WLAN (Wireless Local Area Network) applications is proposed. The antenna structure consists of a microstrip patch array of 3 by 3 OCFA (off centered feed array) that is coaxial feed through type antenna with Unbalanced characteristic whereby the feed line situated off centered λ/3 to the left and...
This paper presents the design and analysis of a Dual Rectangular Ring Microstrip Antenna with Defected Ground Structure (DGS) for wireless application. The antenna design was created in Computer Simulation Tool (CST) ver 2009, using the rectangular ring as a patch, applied the feed line technique and also DGS technique to improve the antenna's performance. This antenna design will be applied to 3G...
