Abstract: A novel antenna structure is proposed by combining the concept of a reconfigurable and fractal with the parasitic elements technique to obtain the multiband frequency reconfigurable antenna. Fractal antenna with triangular slot is designed for operating at multiple frequencies. The integration of PIN diode switches to the antenna changes the frequency of the antenna dynamically. This ...

Abstract The article proposes design investigation and experimental results of a coplanar waveguide (CPW) fed square slot antenna that gives wideband circular polarization. This polarization characteristic is achieved by embedding shape stub to left bottom corner an L-shaped strip the right upper slot. A high impedance bandwidth 87.8 % (3.6–9.0 GHz), wide axial ratio 73.05 (4.2–9.0 GHz) 3-dB be...

New configuration of multiband / broadband Planar inverted FAntenna (PIFA) is investigated. The antenna is a V-shaped patch with unequal arms coupled electromagnetically to single feed triangular PIFA thorough two unequal slots' dimensions. The six multiband operations are achieved due to the different lengths and widths of the V-shaped patch as well as the two coupling slots. Two more modes ca...

This chapter focuses on the design of compact planar multiband antennas intended for exist‐ ing wireless services including LTE, GPS, GSM, PCS, DCS, GPS, UMTS, WLAN and Wi‐ MAX bands. The present techniques available in the open literature include the modification of the main radiator via bending, folding, meandering and wrapping. Each approach offers different advantages, depending on the requ...

With the tremendous advancements in wireless communications, there is an increasing demand for miniature, low-cost, easy-to-fabricate, multiband and wideband antennas for use in commercial communications systems. As a part of an effort to further enhance modern communications systems technology, researchers have been studying different approaches for creating novel and innovative antennas. The ...

A Dielectric Resonator loaded Substrate integrated waveguide cavity backed slot antenna (SIDRA) is proposed for two slot polarizations and orientation. A SIW-fed cylindrical DRA using rectangular slot is used for obtaining bandwidth of about 5% at 6.15 GHz. For enhancing bandwidth, a plus shaped slot with bandwidth of about 8.80% and gain of 3.7 dB is proposed. The proposed antenna represents S...
