Hybrid polarized microstrip antenna for multifrequency application

Abstract

In this article, a novel single layer, single‐fed ring antenna is analyzed for multiresonance operation in WLAN/Wi‐MAX bands. The antenna geometry consists of a square patch with a dual square ring enclosure which commit multiresonance characteristics. The antenna is excited using electromagnetically from a separate feed patch placed in between the rings. The impedance characteristics are enhanced up to 18% using a unique hourglass type feed patch in between the square rings. The suggested antenna exhibits good return loss at 2.45, 3.5, and 5.8 GHz having bore sight gain response of ≅5normaldnormalBnormali. Hybrid polarization is comprised with circular polarization and dual‐linear polarization characteristics are investigated in this research work. This antenna was implemented on Arlon's substrate with dielectric constant Єr = 2.55 and substrate thickness h = 1.524 mm. A good axial ratio is achieved with optimized corner truncation.

Dual polarized triple wideband circular microstrip antenna for GSM and satellite applications

“…Complex multiple feeding techniques and multiple patch parameters increases the complexity of the configurations as reported in Refs. 26‐28. Also they offer lesser BW.…”

“…The theoretical analysis can be determined through given mathematical relation; Altering the physical length can indirectly change the resonances [16]. The clear derivation of the mean perimeter and its effect is well described in [17].…”
