Abstract-A wideband slotted multifunctional reconfigurable antenna is proposed for WLAN/WiMAX/UWB/PCS-DCS/UMTS applications. The proposed antenna consists of monopole and spiral sections and microstrip feeding. A microstrip patch on FR4 substrate provides wideband return loss for each application. Total area of the antenna is 34×45 mm 2 that satisfies all the requirements for different applications in a low profile structure. Reconfigurable design is used in this antenna using RF MEMS switches. The proposed antenna has a nearly omnidirectional radiation patterns (doughnut shape) in different frequency bands. The notch is embedded in the ground plane to improve the impedance matching, and the dimensions of this notch are optimized. Moreover, the variation of group delay is about ±2 ns in UWB application. Also a prototype of the proposed antenna is fabricated, and the results are compared with those obtained from simulations. Measured return losses are in good agreement with simulated ones. The proposed antenna has the advantages of multifunctional operation, low profile, low cost and omnidirectional pattern.

“…In order to fulfill such type of requirement, there are three methods reported in the literature, i.e. higher order mode generation , use of parasitic elements with resonating structures , and hybrid antennas . First method (generation of higher order modes) is quite easy to generate multiband characteristics in DRA such as Fang et al proposed conformal strip‐loaded CDRA .…”

This article investigates modified annular ring patch fed cylindrical dielectric resonator antenna (CDRA) with hybrid mode excitation. The present article comprises of two main aims (i) generation of HE11δ and HE12δ mode in CDRA with the support of modified annular ring patch, both the hybrid modes radiates in broadside direction and (ii) achieve triple band characteristics by using the concept of hybrid antenna. The proposed antenna design is functioning in three different frequency bands, i.e. 1.92–2.3 GHz, 3.13–4.6 GHz, and 5.4–6.5 GHz. The simulated outcomes are verified by using archetype of proposed antenna. The practical outcomes indicate good settlement with simulated outcomes. The proposed antenna structure is appropriate for WLAN/WiMAX applications. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:120–125, 2017

In this article, low-profile and compact cylindrical dielectric resonator antenna along with circular slots and filtering structure for wireless application is reported. Proposed antenna is excited by annular-shaped microstrip line. Two ring-shaped resonators placed on opposite sides of feed line are working as a band-pass filter. These resonators are unified with wideband cylindrical dielectric resonator antenna and make it suitable for triple band operations with better isolation level. Dual ringshaped parasitic slots on a partial ground plane are used to make CDRA more compact. The proposed triple band antenna has been analyzed, studied and optimized using Ansoft HFSS simulation software. Prototype of proposed geometry has been fabricated and tested. There is a better accord between simulated and measured results. The proposed design engenders three frequency bands i.e. 2. GHz with a resonant frequency of 2.45, 3.55, and 5.35 GHz, respectively. Proposed antenna design may find suitable applications for WLAN (2.4/5.2 GHz) and WiMAX (3.5 GHz) bands. The proposed design shows an average measured gain of 4.71 dB in the three desired bands.
