A compact ultra-wideband (UWB) antenna with tunable band notched characteristics is proposed. Varactor loaded, two via edge located (TVEL) and fractal electromagnetic band gap (EBG) structures are designed for tunable band-notched characteristics. The varactor diode near the TVEL EBG tunes the band-notch frequency for WiMAX (2.8-4.0 GHz) band, while another varactor near fractal EBG structure tunes band-notch frequency for WLAN (4.7-6.2 GHz) band. The varactors are independently controlled to achieve WiMAX and WLAN notched band. Notch frequencies can be continuously tuned by varying the bias voltage across the varactors. The proposed antenna of 24 × 24 mm 2 dimensions is fabricated on an FR4 substrate. A good agreement between simulation and measurement results is obtained. A continuous band notch tuning from 2.8-4.0 GHz and 4.7-6.2 GHz is obtained using varactor diodes having capacitance in a range of 0.497-2.35 pF.

“…Recently, many authors have proposed the use of EBG structures near the feed line of the monopole antenna to reject the interfering bands in the UWB spectrum with minimal effect on the radiation properties of the antenna [16][17][18][19][20][21][22][23][24][25]. In [16], four CMT EBG structures are placed near the feed line of circular-shaped UWB monopole antenna to obtain band notch at the center frequency of 5.5 GHz.…”

Electromagnetic Band Gap (EBG) structures can be employed near the feed line of a UWB monopole antenna, to reject the already existing narrowband radio signals operating within the spectrum of an Ultra Wide Band (UWB) antenna. Multiple EBG structures are required to reject multiple interfering bands. However, since the ground plane of a monopole antenna is limited, there is a need for compact EBG structures. This paper presents the application of a Two Via Slot (TVS) EBG to reject the interfering upper Wireless Local Area (WLAN) band (5.725 GHz-5.825 GHz) from the spectrum of a fork-shaped UWB monopole antenna. The simulated results demonstrate that the TVS EBG gives better performance in terms of higher and sharper Voltage Standing Wave Ratio (VSWR) value at the rejection band while occupying least ground plane area than Conventional Mushroom Type (CMT) EBG, Edge Located Via (ELV) EBG, slotted-patch ELV EBG, and semi-circular EBG. The proposed design is fabricated and measured. The measurement results prove that the antenna successfully achieves wide impedance bandwidth from 3 GHz to 12 GHz while rejecting the frequencies from 5.4 GHz to 5.9 GHz.

Purpose Application of electromagnetic band gap (EBG) i.e. electromagnetic band gap technique and its use in the design of microstrip antenna and MIC i.e. microwave integrated circuits is becoming more attractive. This paper aims to propose a new type of EBG fractal square patch microstrip multi band fractal antenna structures that are designed and developed. Their performance parameters with and without EBG structures are investigated and minutely compared with respect to the resonance frequency, return loss, a gain of the antenna and voltage standing wave ratio. Design/methodology/approach The fractal antenna geometries are designed from the fundamental square patch and then EBG structures are introduced. The antenna geometry is optimized using IE3D simulation tool and fabricated on low cost glass epoxy FR4, with 1.6 mm height and dielectric materials constant of 4.4. The prototype is examined by means of the vector network analyzer and antenna patterns are tested on the anechoic chamber. Findings Combining the square fractal patch antenna with an application of EBG techniques, the gain of microstrip antenna has been risen up and attained good return loss as compared to the antennas without EBG structures. The designs exhibit multi-frequency band characteristics extending in between 1.70 and 7.40 GHz. Also, a decrease in antenna size of 34.84 and 59.02 per cent for the first and second iteration, respectively, is achieved for the antenna second and third without EBG. The experimental results agree with that of simulated values. The presented microstrip antenna finds uses in industrial, scientific and medical (ISM) band, Wi-Fi and C band. This antenna can also be used for satellite and radio detection and range devices for communication purposes. Originality/value A new type of EBG fractal square patch microstrip antenna structures are designed, developed and compared with and without EBG. Because of the application of EBG techniques, the gain of microstrip antenna has been risen up and attained good return loss as compared to the antennas without EBG structures. The designs exhibit multi-frequency band characteristics extending in between 1.70 and 7.40 GHz, which are useful for Wi-Fi, ISM and C band wireless communication.
