“…Furthermore, two small slots with a width of 0.5 mm are introduced in the ground plane for biasing D 1 and D 2 , and two 10 pF capacitors are mounted across the slots to provide RF wave connection throughout the ground plane. For biasing D 3 and D 4 , three biasing strips are etched beside the feed line, and three 12 nH inductors are joined for isolating the RF signals while maintaining the dc connection. Meanwhile, a 10 pF capacitor is placed in the feed line to prevent the dc current flowing into RF source of the antenna.…”

A wideband slot antenna with frequency-and pattern-reconfigurable characteristics for TD-LTE (3.4-3.8 GHz) and C-band (3.7-4.2 GHz) applications is proposed. The antenna consists of two symmetric slots that are fed by a fork-shaped microstrip line. Two PIN diodes are loaded in the slots to produce two different frequency bands. Meanwhile, two additional PIN diodes are inserted in the feed line to achieve the pattern reconfigurability. The wideband operation is realized by using the symmetric slots and fork-shaped feed line. Simulated and measured results show that the antenna provides 25°and 20°beam-steering in 3.4-3.8 and 3.7-4.2 GHz bands, respectively. Also, an impedance bandwidth of at least 12.8% is obtained in the operating bands.

“…A number of reconfigurable antennas have been reported. In [4][5][6], the antennas can switch between different resonant frequencies by changing the states of the PIN diodes. In [7], a lumped capacitor is inserted in the middle of a slotted patch antenna, and the operation bands can be tuned continuously.…”

“…In [11], frequency reconfigurable antenna using a thick substrate (3.3 mm thickness) is presented in which resonance is controlled by shorting strips; moreover, the conical radiation pattern is maintained even at higher frequencies. A compact frequency reconfigurable antenna proposed in [12] utilizes a simple square shaped radiating patch for Bluetooth, WLAN, and WiMAX applications. Three pin diodes are inserted in ground plane that controls switching bands.…”

“…In order to achieve multi-frequency response several techniques have been applied such as electromagnetic band gap structure (EBG) [9], ring resonator, defected ground structure antenna (DGS) [10], multilayer antenna, reconfigurable antennas [11], slots antennas [12], etc. Among these variety of designs, slot antennas offer several advantages such as keeping a low profile structure, single designs (which makes available for mass fabrication), bandwidth improvements, multifrequency response along other antenna improvements.…”

Abstract.A novel design of a multi band microstrip antenna is presented in this work. The double modified U slots planar patch antenna is designed, simulated and fabricated to operate at 2.8 GHz (between 2.794 to 2.846 GHz), at 3.1 GHz (between 3.145 to 3.196 GHz), at 3.6 GHz (between 3.56 to 3.3.644 GHz), at 4.7 GHz (between 4.684 to 4.772 GHz) and at 5.4 GHz (between 5.423 to 5.526 GHz) for WiMAX/WLAN applications. One of the main challenges was keeping a low profile and low cost substrate (1.2mm and FR4 respectively) with penta-band frequency response without scarifying these characteristics. Each resonant frequency is accomplished by modifying each U slot and patch radiator itself. Simulations had been conducted using HFSS software and measured parameters such as reflection coefficient (S11 parameter) was performed with a vector network analyzer. Measured results confirm simulated results that the antenna could work within mentioned frequencies. Parametric study was conducted in order to study the effect of slots variation over the design.
