Design, Simulation and Experimental Analy- Sis of Wideband Circularly Polarized Capac- Itive Fed Microstrip Antenna
Wideband Circularly polarized antenna receive much attention in the wireless communication applications such as Global positioning system (GPS) and Personal communication system (PCS). In this paper, a microstrip square patch, truncated in opposite corners, suspended above the ground plane is proposed. The geometry incorporates the capacitive feed strip which is fed by a coaxial probe. The prop...
متن کاملWideband Circularly Polarized Microstrip Patch Antenna for Wireless LAN Applications
A small wideband microstrip patch antenna is introduced. The antenna is designed to function in the 5-6 GHz wireless LAN bands. It achieves multi-band functionality through the addition of a slot to a square patch (21 mm by 21 mm by 2.6 mm). The proposed antenna also generates circular polarization and has a 3 dB axial ratio bandwidth of 2.8%. The impedance bandwidth of the antenna is more than...
متن کاملA Capacitive Fed Microstrip Patch Antenna with Air Gap for Wideband Applications (RESEARCH NOTE)
In this paper a microstrip antenna on a suspended substrate with capacitive feed is presented. capacitive feed is created by a slot within the rectangular patch around the feed point. The proposed antenna exhibits a much higher impedance bandwidth of about 47% (S11 < −10 dB). Effects of key design parameters such as the air gap between the substrate and the ground plane, the gap width between r...
متن کاملDesign of Slot Cut Circularly Polarized Rectangular Microstrip Antenna
Circularly polarized slot cut rectangular microstrip antenna on thinner substrate is proposed. The dimensions of the slots are modified such that the resonance frequencies of the two orthogonal modes are close to each other to realize circular polarization. To improve upon the gain, three layer suspended configuration is proposed which yields VSWR and axial ratio BW of 40 and 9 MHz, respectivel...
