Wideband 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 WIDEBAND CIRCULARLY POLARIZED MICROSTRIP PATCH ANTENNA FOR 5–6-GHz WIRELESS LAN APPLICATIONS
A wideband slotted circularly polarized (CP) patch antenna is introduced for 5–6-GHz WLAN applications. A small 14.6 14.6 mm square patch on Duroid 5880 substrate can provide a returnloss bandwidth of 11% and an axial-ratio bandwidth of 8% with a single feed. A possible reconfigurable design achievable using PIN diode or MEMS switches capable of left-hand or right-hand circular polarization is ...
متن کاملCircularly Polarized Patch Antenna With Enhanced Band Width & Gain
In this paper, one 5 × 5 antenna array are studied. In each array, one probe-fed circularly polarized (CP) microstrip patch antenna is placed at the center as the driven antenna and is gapped coupled to the remaining elements. It is investigated that CP performance of the patch can be proved by properly arranging these parasitic elements. The driven patch is a perturbed square one with two diag...
متن کاملGain Enhancement of the Patch Antenna Using TSRR NRI Superstrate
This article presents a high gain patch antenna with negative refractive index (NRI) superstrate for the application of Radio frequency energy harvesting system. Triangular split ring resonators (TSRR)-strip line are used as a NRI superstrate to enhance the gain of the patch antenna. It is demonstrated that the proposed triangular split ring resonator (TSRR) structure metamaterial yields negati...
متن کاملCPW-Fed Circularly Polarized Slot ANTENNA with Elliptical-Shaped Patch for UWB Applications
A new design of coplanar waveguide (CPW)-fed antenna with circular polarization (CP) and excellent impedance matching is presented. In this design a pair of circular-shaped slits is applied to opposite corners of the slot for enhancing the impedance matching and realizes bandwidth of 134.43% across 2.98-15.20 GHz for VSWR≤2. Furthermore this structure exhibits axial ration bandwidth (ARBW) of 3...
