“…This poses a design challenge for the microstrip antenna designer to meet the broadband techniques [2,3]. There are numerous and well-known methods to increase the bandwidth of antennas, including increase of the substrate thickness, the use of a low dielectric substrate, the use of various impedance matching and feeding techniques, the use of multiple resonator, and the use of slot antenna geometry [4][5][6]. However, the bandwidth and the size of an antenna are generally mutually conflicting properties, that is, improvement of one of the characteristics normally results in degradation of the other.…”

Abstract-A new high gain wideband L-probe fed inverted EE-H shaped slotted (LEE-H) microstrip patch antenna is presented in this paper. The design adopts contemporary techniques; L-probe feeding, inverted patch structure with air-filled dielectric, and EE-H shaped patch. The integration of these techniques leads to a new patch antenna with a low profile as well as useful operational features, as the broadband and high gain. The measured result showed satisfactory performance with achievable impedance bandwidth of 21.15% at 10 dB return loss (VSWR ≤ 2) and a maximum gain of 9.5 dBi. The antenna exhibits stable radiation pattern in the entire operating band.

Abstract-A new defected ground structure (DGS) is firstly proposed in this paper, which has better slow-wave effect than that of cross or dumbbell one. Using the model of transmission line, its equivalent parameters are extracted. With good omni-directional properties, the proposed DGS is then used in the design of a proximity coupled antenna for its miniaturization. The size of the developed antenna is about 68% smaller than that of the conventional one. Further, two artificial cells are added on the feed line to reduce the protrudent stub length from 26.9 mm to 18.94 mm. With the utility of the DGS and artificial cells, the size of proximity coupled antenna is reduced significantly. By introducing a PIN diode at the end of feed line, the antenna is switchable in both x-and y-direction linear polarizations. Such miniaturization in antenna size has little negative effect on its cross polarization, with both simulated and experimental results presented for comparison.

“…However, it was pointed out [6] that using a higher patch height could cause a higher cross-polarization level. And, the antenna gain drops to 5 dBi, which is lower than other wide-band patch antennas [4,5]. Some other techniques as utilizing the shorting pins or shorting walls on the unequal arms of a U-shaped patch, U-slot patch, or L-probe feed patch antennas, wideband and dual-band impedance bandwidth have been achieved with electrically small size in [7,8].…”

Abstract:A high gain W-shaped microstrip patch antenna is proposed and experimentally investigated. The patch antenna employs a new inverted W-shaped patch structure with meander probe feed technique. A prototype of the proposed antenna is fabricated and tested for validation. This low-profile antenna is operating for the frequency band of 1.84 GHz to 2.29 GHz. It exhibits an impedance bandwidth (2 : 1 VSWR) of 21.79% and a high gain of 10.46 dBi at the frequency of 2.11 GHz. The measured result shows the stable radiation characteristics, including a low cross-polarization level below −20 dB in both planes.
