Circuital characteristics and radiation properties of an UWB electric‐magnetic planar antenna for Ku‐band applications

Abstract

[1] A planar, directive antenna with large fractional bandwidth is introduced in this paper. A detailed discussion on the proposed antenna topology and its architecture is reported. The proposed element is a combination of a patch and a loop radiator. A proper combination of the electric field radiator (patch) with a magnetic field radiator (loop around the patch) is exploited for expanding the operational bandwidth. A parametric study is presented to investigate the effect of the antenna geometrical parameters on its performance. A general and computationally efficient procedure for extracting the antenna equivalent circuit is described and used to achieve a meaningful circuit theory-based insight into the characteristics of the radiating structure. The theoretical and experimental results are compared, and it is demonstrated that the element features over 100% fractional bandwidth, good impedance matching, and unidirectional and stable radiation patterns.Citation: Haider, N., D.

Recent Developments in Reconfigurable and Multiband Antenna Technology

“…In Section 4, some examples of reconfigurable antenna with tunable or switchable components have been provided. Another approach is to use ultrawideband or multiband antenna elements [45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60]. In this approach, one needs antenna solutions which feature good performance (good impedance matching, radiation pattern, gain, etc.)…”

“…A nondispersive wideband antenna has been used as the radiating element. The antenna concept is based on the combination of the electromagnetic characteristics of a loop and a planar monopole [48,49].…”

Single Waveguide Feed Omnidirectional and Circularly Polarized Transceiver Waveguide Slot Antenna for Satellite Communication Applications

“…The proposed antenna is demonstrated on Ku‐band, which is popular band on satellite communication (Fukao et al., 1985; Haider et al., 2013). While the parametric design of the proposed method is performed with Computer Simulation Technology (CST), the corresponding prototype is manufactured with 3D printing technology and metal spray coating.…”
