With the help of proximity coupling, preferred resonating modes can be excited with proper impedance matching as it allows flexible feed line design . Many works in the designing of broadband proximity‐coupled microstrip antennas (PCMAs) have been reported in literature, such as U‐slotted patch with ᴨ, double ᴨ‐shaped stub, V‐slotted patch with Y‐shaped stub, tooth‐like‐slot‐patch, and so on.…”

“…In order to avoid interference with nearby communication systems, there is a requirement to place the multiple resonances distantly so that an antenna can operate only at the desired frequency bands. Multiband PCMAs have got some attraction toward the researchers . ‐ These antennas are either for only two bands or complex in structure .…”

A novel and simple design of a multi‐band proximity coupled microstrip antenna for operating in the WiFi (2.4–2.48 GHz), WiMAX (3.44–3.53 and 5.25–5.85 GHz), and WLAN (5.15–5.35 GHz and 5.470–5.725 GHz or 5.725–5.825 GHz) bands is proposed. Apart from that, an additional band covering (3.8–4.2 GHz) is achieved, which may be used for fixed satellite communication. The proposed multiband antenna consists of a V‐slotted patch in conjunction with parasitic element, and L‐shaped microstrip line feed structure. Slot in the patch is introduced to reduce the overall size of the antenna and L‐shape feed is used for proper energy coupling to the parasitic element. The simulated gains are 3.47/1.62/0.72/6.22 dBi at 2.44/3.5/3.8/5.5 GHz, respectively, and the antenna shows broadside radiation characteristics. The simulated results are in good accord with the measured results.

“…However, there is considerable challenge to realize a small internal multiband antenna design to fit in new portable systems. Extensive research activities have been published toward the development of multiband antennas for wireless USB dongle applications [2,3], monopole antennas [4][5][6], and planar inverted-F antennas [6]. However, these complicated antennas cannot cover bandwidths broad enough for future communication requirements, especially for GSM 1800/1900/UMTS 2100 and LTE700/2300/2500 bands [12].…”

Abstract-A 3D compact printed monopole antenna for most of the wireless communication applications is proposed in this paper. The proposed antenna has dimensions 40 × 30 × 1.6 mm 3 ; it is based on multi different length arms of E-shaped monopole with modified ground plane coupled with meander line. The performance of the 3D antenna is almost the same as a 2D antenna with reduction in size, and it could be fit in a wireless transceiver device. The size reduction about 25% compared to the 2D planar proposed antenna is realized on a printed circuit board to reduce the fabrication cost. The coupling between the antenna elements broadens the operating bandwidth, which includes most of the wireless commercial service bands, GSM1800/GSM1900/ UMTS/WCDMA2100 802.11b/g/LTE2600 (2690 MHz) as well as 802.11a/n (5150-5825 MHz). The antenna's simulated and experimental results are in good agreement. It is fabricated on a low-cost FR4 substrate and measured to validate the simulation performances. Measured results display that the proposed antenna produces omnidirectional radiation pattern of −6 dB impedance bandwidth at multi operating bands and average gain of 3.5 dBi and 2 dBi for 2D and 3D, respectively over the operating band.

“…Previous works include stacked patch radiators [1], [2], slots on patch radiator [3], [4], interconnected patch or slot radiators and defected ground planes [5][6][7]. These structures either increase the profile of the antenna or consume a significant area of the antenna substrate or cross polar radiation increases.…”
