A Compact Annular Ring Microstrip Antenna for WSN Applications
Antenna is fed by a simple microstrip feedline. This antenna is applicable for Wimax (3.3, 3.5, 5.8 GHz), WLAN (5.1 - 5.8 GHz), Wi-Fi (3.6, 4.9, 5, 5.9 GHz), LTE 42/43 (3.4 - 3.8 GHz), radar and satellite system. Broadband Koch Fractal Boundary Printed Slot Antenna for ISM… All the antennas are fed with a simple microstrip line. Bandwidth achieved with Antenna 1 (IO=1, IF=0.35 and IA=60 0) is 1550 MHz which is five times more than that of the square slot antenna. Design of Coaxial Feed Microstrip Patch Antenna for S Band…

In this paper, a single layer asymmetric L-slot loaded microstrip patch antenna for circular polarization is proposed. The suggested L-slot excites the two orthogonal patch modes in phase quadrature for circular polarization without truncating any corner of the probe feed square patch. A novel design of a CPW-fed square slot antenna with… square slot antenna fed by a single coplanar waveguide is proposed and discussed. The circularly polarized radiation is achieved by means of using anAnother new configuration of annular ring has been studied. Theoretical analysis of CDM and annular ring antennas have been carried out using... Multi-band Annular Ring Microstrip Antenna with... -…
Miniaturization and Bandwidth Enhancement of a CPW-Fed ... 2. CPW-FED ANNULAR SLOT ANTENNA DESIGN In this work, a conventional annular slotted structure is employed as the reference antenna. Geometry of the annular slot antenna with a CPW-feed line is shown in Figure 1(a). In general, a microstrip slot antenna is very popular due to its compact, low-profile and easy to integrate with monolithic microwave A Compact Annular Ring Microstrip Antenna for WSN Applications A compact annular ring microstrip antenna was proposed for a wireless sensor network (WSN) application in the 2.4 GHz band. In this paper the major considerations of the conformal antenna design were the compact size and the impact on antenna's performance of a steel installation base. By using a ...
