In this article, an ultra wideband ring antenna with a fractal formation for notch application is presented. The antenna was printed on FR-4 substrate, which was a low cost one with the relative permittivity of 4.4 and thickness of 1.6 mm. The total dimension of antenna was 50 mm 3 50 mm. It could be applied as a notch antenna for propagation rejection in IEEE 802.11a for instance by covering were as without conflicting with wireless systems. The prototype antenna presented in this article, has a rejection band at 5-6 GHz and covers the frequency range of 2.1-11 GHz with the VSWR of less than 2. For improvement of the notch frequencies and for obtaining dual notch band characteristic some changes in prototype antenna with a slot at fractal structure have been performed. The final antenna had dual notch band at 2.5 and 5.5 GHz. The current distribution in the notch frequency has been provided. The efficiency has also been checked for the entire frequency band. The maximum antenna gain was achieved between 2-8 dBi. All the simulations were done in HFSS and compared with the experimental results.

A new broadband and dual band circular slot cut modified circular microstrip antenna is analyzed and proposed. The parametric study to analyze the effects of circular slot which realizes broader bandwidth is presented. The circular slot creates two additional resonant modes near the fundamental TM 11 mode resonance frequency of the equivalent circular patch and yields bandwidth of 202 MHz (8%). The polarization of the two modes which realizes broadband response was found to be orthogonal, which leads to the principal plane variations over the bandwidth. Further by using this concept, a circular slot cut dual band and dual polarized circular slot cut circular microstrip antenna in 1000 MHz frequency band is proposed. The proposed antenna yields dual frequency response with orthogonal polarization and variable frequency ratio with bandwidth of 2% at the dual frequencies.

In this manuscript microstrip patch antenna loaded with multilayer liquid metamaterial radome (superstrate) structures for gain enhancement is presented. The antenna superstrate is loaded with three ring split ring resonator (SRR) metamaterial. Two multilayer radome structures used for enhancement of gain and protection of conventional microstrip patch antenna. First multilayer structure is made with six equal layers of three ring SRR and second multilayer structure is made with four log periodic layers of three ring SRR. The microstrip patch antenna loaded with multilayer SRR radome structure is compared with conventional microstrip patch antenna. The results of proposed design are compared in form of reflection coefficient, gain and bandwidth. The enhancement in gain is achieved by covering antenna with different radome structures.
