“…Similarly, a triband miniaturized monopole antenna has been designed by using a toothbrush‐shaped patch, a meander line, and an inverted U‐shaped patch for WLAN and WiMAX applications. The size of these monopole antennas (as detailed above) could be reduced by folding the monopole, which generate higher order mode along with fundamental . An additional mode, in this structure could be induced if planar structure like square split ring resonator (SSRR) is introduced on the substrate along with the radiating element .…”

In this article, a folded monopole antenna loaded with complementary split ring resonators (CSRRs) is proposed for tri‐band applications. The two bands of the antenna are generated by the folding of the monopole (first band is caused due to fundamental mode and another due to higher order mode) and CSRRs have been responsible for the third band. By using four such antennas in form of an array, the gain and bandwidth have been improved. The prototype of the antenna array is developed on FR4 substrate and simulated results are experimentally validated. A simplified equivalent circuit model of the antenna has been developed and analyzed to quantify the power loss due to input impedance mismatch at each resonance frequency. By using the EM model of the proposed antenna in the Keysight ADS verification test bench its suitability to operate in the system environment has been confirmed.

“…Folded dipoles had been known for many Manuscript decades as an approach to increase the dipole impedance by a factor of 4 for impedance matching purpose [8]. Lately, it was proposed to enhance the radiation resistance of a meandered folded monopole in free space above a ground plane [9], [10]. It was demonstrated that the radiation resistance, bandwidth, and efficiency of a meandered monopole increase substantially by antenna folding.…”

Abstract-This letter presents a wire folding scheme to enhance the bandwidth of an electrically small resonant microstrip antenna. As an example, meandered two-wire slow-wave lines spread on both sides of a dielectric slab short-circuited at both ends form a vertically folded printed dipole. It is found that the radiation resistance increases by about a factor of 4, and the energy storage increases by about a factor of 2, using a folded dipole. It is shown through both measurement and simulation that the -factor is reduced by about 50% through antenna folding. A 0 14 -long folded dipole resonant at 2.43 GHz shows a bandwidth of about 4.8%. The proposed folding method facilitates planar antenna miniaturization with sufficient bandwidth.Index Terms-Electrically small antenna (ESA), folded dipole, microstrip, slow-wave structures.
