“…More examples of miniaturizing dipole and bow-tie antennas can be found in [14][15][16][17], etc. But most of the designs discuss antenna miniaturization techniques for high frequency UWB and RFID applications, hence, it is ideal to focus on miniaturization techniques of low frequency antennas.…”

Abstract-In this paper, a miniaturized dipole antenna operating at 100 MHz frequency for Ground Penetrating Radar (GPR) application is presented. A conventional dipole antenna length is half of its lowest operating frequency wavelength. As low frequency GPR system is vital for high depth penetration, the size of the antenna used reduces its easy handling and portability. Therefore, the technique of miniaturizing a dipole antenna by adding extra radiating arms is presented here. The antenna design and analysis is carried out using Advanced Design System (ADS) and FEKO simulation software, and a network analyser is used to validate the prototype antenna performance. The antenna of 66.5 × 22 cm dimension, fabricated on an FR4 substrate exhibits a frequency resonance at 104 MHz with 8 MHz of −10 dB bandwidth. The proposed antenna radiates in omnidirectional pattern and features 55% reduction in length compared to a conventional dipole antenna of same frequency operation.

“…Several novel planar dipole antenna structures have been proposed to widen the impedance matching bandwidth [18][19][20][21][22]. Cappelletti et al present a drop-shaped dipole antenna which can be used to realize compact array antennas or to reduce the spurious radiation level in the direction of feeding line [18].…”

“…A planar dipole UWB antenna with two semielliptical-ended arms connected by a shorting bridge is proposed to achieve enhanced impedance and gain performance [19]. Printed dipole antenna with integrated balun provides wideband impedance matching with miniature size [20]. In [21], a novel wideband balanced loop-dipole composite antenna with end-fire radiation is presented.…”

A coplanar waveguide-(CPW-) fed dual-band-notched antenna with sharp skirt selectivity for ultrawideband (UWB) applications is presented. The proposed antenna is composed of a radiant patch with a C-shaped slot and a C-shaped stub on the back surface of the substrate. By using the C-shaped slot and the C-shaped stub, dual-band-notched characteristics can be generated. In this way, a more practical and effective approach to design an UWB antenna with sharp notched-band-edge selectivity is developed. The measurement results show dual notched bands of 4.96-5.42 GHz and 5.71-5.91 GHz, which can reject the interference between IEEE 802.11a bands (5.15-5.35 GHz and 5.725-5.825 GHz) and UWB systems. The fabricated antenna shows good omnidirectional radiation patterns with acceptable gain and group delay.

“…While Tdipole antennas can be fed by various types of balun with [4]- [6] or without [4], [7], [8] via holes, quasiYagi antennas can be fed by alternative feeding lines, including microstrip line [9], coplanar waveguide [10], coplanar stripline [11], and slotline [12]. Especially, quasi-Yagi antennas have highly directional and endfire radiation pattern, which are promisingly suitable for WLAN APs.…”
