Effective Microstrip Feed Line Length in Ultra-Wideband Responses and Wireless Applications

In this paper, staircase-shaped ultra-wideband (UWB) response is proposed. UWB technology being emerging technology of decade needs development of antennas with small size. This paper proposed the design of antennas for UWB technology with small overall size. The feed used in the proposed design is microstrip feed line. The defected ground structure and staircase patch have been used to enhance bandwidth (BW) of antenna, to miniaturize its shape and to reduce the surface wave. The proposed design is carried out with different types of substrate materials and the best results are considered. The proposed antenna performs well in terms of BW and gain while reduction in size is reported. The proposed antenna can be used for Wireless Personal Area Network.

Abstract A circularly polarized ring cylindrical dielectric resonator antenna (ring-CDRA) of wideband impedance bandwidth is presented in this article. The proposed ring CDRA consist of an inverted rectangular (tilted rectangular) shaped aperture and inverted L-shaped slotted microstrip feed line. The tilted rectangular shaped aperture and inverted L-shaped microstrip feed line generate two-hybrid mode HEM11δ and HEM12δ while ring CDRA and slotted microstrip feed line are used for the enhancement of impedance bandwidth. The proposed ring CDRA is resonating between 6.08 and 12.2 GHz with 66.95% (6120 MHz) impedance bandwidth. The axial ratio (AR) bandwidth of 6.99% (780 MHz) is obtained between 10.76 and 11.54 GHz with a minimum AR value of 0.2 dB at a frequency of 11 GHz. The proposed geometry of ring CDRA has been validated with measurement performed by VNA and anechoic chamber. The operating range of the proposed radiator is useful for different applications in X-band.

A Multi Input Multi Output (MIMO) Rectangular Dielectric Resonator Antenna (RDRA) for 1.8 GHz Long Term Evolution (LTE) applications is investigated and presented. The antenna consisting of two rectangular dielectric resonator elements, both resonators are fed by microstrip feed line is etched on FR4 substrate. The simulated impedance bandwidth for port1 and port2 is 26.38% (1.6176-2.1093 GHz) and 26.80% (1.6146-2.1143GHz) respectively for |S11| ≤ -6dB, which can operate on LTE band 1-4,9,10,35-37 and 39. The gain of the MIMO RDRA is 3.2 dBi and 3.1 dBi at 1.8 GHz for port 1and port 2, respectively. The S-parameters, isolation, gain, and MIMO performance such as correlation coefficient and diversity gain of the presented RDR Antenna have been studied.

AbstractA polarization and band reconfigurable cross-slot antenna for multiband applications is presented in this paper. The antenna consists of four p–i–n diodes embedded in the cross-shaped slot in a ground plane and excited by a microstrip feed line. The p–i–n diodes are placed in such a way that they produce multiple bands, with linearly and circularly polarized (CP) radiation. By switching the states of the p–i–n diodes, the sense of rotation of the electric field in CP radiation can be reconfigured. The proposed structure can be configured to produce two bands that radiate linearly polarized waves or three bands, where, two are linearly polarized and one is CP. The proposed design concepts are validated bythe CST studio suite as well as measurementsare carried out on fabricated prototypes.
