Double-Sided Microstrip Circular Antenna Array for WLAN/WiMAX Applications
The design, fabrication, and characterization of the microstrip circular antenna arrays were presented. The proposed antennas were designed for single band at 2.45 GHz and dual bands at 3.3 3.6 and 5.0 6.0 GHz to support WLAN/WiMAX applications. The proposed single and dual band antennas showed omnidirectional radiation pattern with the gain values of 3.5 dBi at 2.45 GHz, 4.0 dBi at 3.45 GHz, a...
متن کاملA Broadband Suspended Microstrip Antenna for Circular Polarization
In this paper we propose a circularly polarized (CP) microstrip antenna on a suspended substrate with a coplanar capacitive feed and a slot within the rectangular patch. The antenna has an axial ratio bandwidth (< 3 dB) of 7.1%. The proposed antenna exhibits a much higher impedance bandwidth of about 49% (S11 < −10 dB) and also yields return loss better than −15 dB in the useful range of circul...
متن کاملCompact CPW-fed Circular Patch Antenna for UWB Applications
In this paper, a novel CPW-fed antenna is presented for UWB applications. The antenna mainly comprises of a simple circular patch and a modified ground plane. The inclusion of two novel symmetrical rectangular slots with inner area of 3×2.8 mm2 to the top corners of the antenna creates a new path for the current and consequently leads to the bandwidth enhancement. A rectangular stub is also ado...
متن کاملSuspended Hexagonal Microstrip Antennas for Circular Polarization
Suspended hexagonal microstrip antenna with a single coaxial feed has been proposed for circular polarization. The configuration has been realized by inserting perturbations along two opposite sides of the suspended hexagonal microstrip antenna. The broad bandwidth of 70 MHz has been obtained corresponding to VSWR < 2 and 3 dB axial ratio bandwidth of 16.2 MHz has been achieved for the suspende...
متن کاملWall Admittance of a Circular Microstrip Antenna
The formulation of the wall admittance of a circular microstrip antenna by the spectral domain method is presented. The circular microstrip antenna is calculated using the cavity model. The electromagnetic fields within the antenna cavity are determined from the impedance boundary condition at the side aperture. The contribution from the region outside the antenna is taken into account by the w...
