“…The simulated |S 11 | and the input impedances for two reference antennas and the proposed antenna are plotted in Figures and . As shown in Figure , for Ref , two resonances at 0.75 GHz (mode 1) and 1.5 GHz (mode 3) are generated. Here, the resonances at 0.75 GHz and 1.5 GHz are 0.25λ fundamental resonances of the longer slot arm and branch AE, respectively.…”

“…Recently, many promising methods, such as the lumped element matching method, the coupled‐fed method, and the multiple mode method, have been proposed for reducing the ground clearance. For example, an inverted‐T open‐slot tablet computer antenna is fed by two feedlines with additional LC match circuits, and a new resonance can be generated to achieve the entire WWAN/LTE band coverage.…”

A low profile octa‐band antenna with a small size of 74 × 5 × 0.8 mm3 for the WWAN/LTE metallic narrow‐frame tablet computer is proposed. The antenna consists of a driven strip and a ground strip. A gap of 2.5 mm in width is disposed at the top of metallic frame, and a T‐shaped open slot is formed by the ground clearance and the metallic frame. As a result, additional slot resonant modes can be excited, and the operating bandwidth of the antenna is widened. With only 5 mm ground clearance, the antenna successfully covers all WWAN/LTE bands without any lumped elements. The antenna is fabricated. The measured results show that the antenna operates in 698‐960 and 1710‐2690 MHz bands with good radiation efficiencies. The proposed antenna is suitable for the metallic narrow‐frame tablet computer applications.

A triple band notch multiple-input-multiple-output (MIMO) antenna is designed and proposed with complementary-split-ring-resonators (CSRR) on upper side and defected ground structure on bottom portion of the FR4 substrate material. A square shaped radiating element with cone shaped microstrip line feeding is used in the current design to achieve 50-ohm impedance. A compact dimension of 36 Â 22 Â 1.6 mm is used to fit this model for portable communication devices. Split ring resonators are placed adjacent to the feed line to improve the gain and defected ground with stubs is placed to enhance the bandwidth characteristics. Proposed antenna has bandwidth ranging from 2 to18 GHz with notching at 5.2-5.8 GHz (WLAN), 11-12 GHz (Satellite Broadcasting) and 12.5-14.5 GHz (Aeronautical Radio Navigation). The envelope correlation coefficient (ECC) is less than 0.005 and mutual coupling is less than 15dB achieved. The prototyped antenna is providing peak realized gain of 5dB and maximum efficiency of 75% in the operating band. The results strongly support the applicability of current antenna model with band notching in wideband communications.
