“…The proposed geometry offers better gain than the configurations in [1,5,14] in the higher bands for a much smaller overall dimension. As far as the lower band is concerned, gain is moderate, but the proposed geometry is of smaller dimension than [15,16]. The realized peak gains in the bands are 0.136, 2.12 and 3.55 dBi, respectively.…”

“…Different techniques, such as slot loaded patch, meander lines, stacked layers, parasitic elements, defects in ground structure (DGS), Metamaterial structures [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16], are used for exciting the antenna at multiple frequencies. In slot loading technique, appropriately placed slots in the resonating patch with different shapes like inverted U [1][2][3], I [4], hexagon [5], circular [6], and L shape [7] are effectively used to produce additional bands.…”

A novel and compact triband planar antenna geometry suitable for DCS/WLAN/WiMAX services is reported. The multiple metal strip geometry in dual F shape is printed on a substrate of dielectric permittivity 4.4 and thickness 1.6 mm. A truncated and asymmetrically placed ground structure is used for improved impedance matching. Feed position is also optimized for good antenna radiation performance. The geometry is simulated using High Frequency Structure Simulator. All the radiation characteristics of the antenna are validated experimentally and found in good agreement with simulation results. Performance of the proposed antenna is compared with other triband antennas reported in the literature. Measured radiation patterns and gain are also presented in this paper. The radiation patterns are validated by EMSCAN Corporation's RFxpert TM application tool also.

“…Planar multiband antenna has attractive design properties viz. low profile and ease in fabrication, hence planar monopole antennas are utilized extensively in handheld devices such as mobile phones, tablet computers, and laptops [3][4][5]. The fundamental cause of this over dependency is due to flexibility in the resonator design.…”

The proposed antenna structure is excited for multiple operational modes by means of meandered strips. The compact planar monopole antenna is demanded enormously for handheld devices especially automatic meter reading and tablet devices. Due to Chu limit, it is extremely vital to miniaturize an antenna by balancing tradeoff between bandwidth and radiation efficiency. The designed antenna is formed by two interconnected broad monopole open slots which covers multi-bands for smart energy meter and tablet computer applications. The cost effective FR4 laminate of size 50 × 200 mm 2 (0.4λ × 1.6λ) is employed to match standard tablet computer communication module dimensions. The impedance bandwidth, for all excited resonant modes, is above typical requirement of 2%, and the VSWR is well below the necessary requirement of 1.5. The peak gain ranges from 0.94 dBi to 1.92 dBi. Radiation patterns along with other antenna parameters are satisfactorily meeting the demand of Wireless Energy Meter and Tablet Devices. The effects of varying dimensions of a monopole on the radiation characteristics have also been presented. The return loss and radiation patterns computed through simulations are validated through experimental measurements in an anechoic chamber environment.

“…Patel et al demonstrated effective use of L and U‐shaped slots defects introduced in the ground plane for providing reactive components internally to produce additional bands. In Reference , a hook‐shaped metal strip antenna with 1 mm slot at the middle to connect a lumped element switch is proposed. It can operate either in 2.45/5.13 GHz bands or in 3.49/5.81 GHz bands based on ON/OFF status of the switch.…”

“…The proposed compact printed monopole antenna consists of Inverted L slot, Pi‐shaped slot and a truncated square patch at left corner for triple‐band operations. The proposed slot antenna has a small size with high peak gain as compared to antennas presented in Reference and has a simple geometry, covering required WLAN/WiMAX bands.…”

This work presents a triband antenna, which is compact, low profile, and covers the bandwidth requirements for WLAN and WiMAX applications. The proposed design is a modified and miniaturized printed monopole antenna. It consists of beveling rectangular patch, a Pi-shape slot element, and an inverted-L slot element to achieve resonance in three bands. The physical size of the antenna is 27.5 × 20 mm 2 while the electrical size is 0.26 λ 0 × 0.23 λ 0 at the lower operating frequency which is very compact as compared to other triband designs. It works in three bands, that is, 2.37 to 2.52 GHz, 3.35 to 3.90 GHz, and 4.97 to 7.85 GHz with |S 11 | < − 10 dB within these operating bands. The prototype of the proposed miniaturized antenna has been fabricated and the measured results are provided for validation. Antenna performance is studied in terms of input match, gain, radiation efficiency, surface current distributions, and radiation pattern. The antenna shows a nearly omnidirectional radiation pattern with peak efficiency of 90% and acceptable gain of 4 dBi over the three operating bands of WLAN and WiMAX. The prototype of the antenna is fabricated, and simulated results have been verified through measurements. K E Y W O R D S compact, monopole, multiband antenna, slots, WiMAX, WLAN
