“…Therefore, dual-band or frequencyreconfigurable components that satisfy various frequency standards have been developed [1,2,3,4,5,6,7]. Unlike a dual-band antenna that always satisfies the condition of two different bandwidths, a frequency-reconfigurable antenna can vary its frequency, and this antenna exhibits reduced interference between the different frequency bandwidths, even though simultaneous multifunctionality is not allowed [5,6,7].…”

In this paper, we propose a novel electrically small dualband reconfigurable antenna. Low-and high-frequency resonances are generated by a substrate-integrated-waveguide (SIW) cavity resonator and a complementary split-ring resonator (CSRR). The overall size is reduced because of the use of an eighth-mode SIW (EMSIW) and an evanescent-mode CSRR. The varactor-loaded CSRR enables only the high frequencies to continuously vary from 2.38 GHz to 2.5 GHz for channel selection of wireless local area network (WLAN), while the low frequencies are fixed at 1.575 GHz for global position system (GPS), because the two resonant frequencies can be independently controlled. The proposed concept is demonstrated by the simulated and measured s-parameters and radiation patterns.

“…Chen et al [9] reported a modified inverted-L monopole with meandered wire and a conducting triangular. A rectangular strip and two lateral strips which are printed on a dielectric substrate are used to design a microstrip dual band antenna for WLAN Applications [10]. In [11], low-temperature cofired ceramic (LTCC) technology is used to design a dual band microstrip antenna for global positioning satellite (GPS) operations.…”

Abstract:In this paper, a new method for designing dual band microstrip antenna is presented. This method can be used to design any dual band microstrip patch antenna with arbitrary resonant frequencies and different frequency ratios. In this method, non-regular polygonal patch is used to design dual band microstrip antenna and particle swarm optimization (PSO) technique and ant colony optimization (ACO) are used to optimize the shape of the patch antenna. This method is used to design a dual band microstrip antenna for satellite application, which has resonant frequencies at 8.6 and 13 GHz.

“…In recent years demand for small antennas on wireless communication has increased the interest of research work on compact microstrip antenna design among microwaves and wireless engineers [1][2][3][4][5][6]. To support the high mobility necessity for a wireless telecommunication device, a small and light weight antenna is likely to be preferred.…”

Abstract-A single feed compact rectangular microstrip antenna is presented in this paper. A triangular slot is introduced at the upper edge of the patch to reduce the resonant frequency. A small piece of triangular patch is added within the area of the triangular slot to improve the gain bandwidth performance of the antenna. The antenna size has been reduced by 46.2% when compared to a conventional square microstrip patch antenna with a maximum of 160 MHz bandwidth and −27.36 dB return loss. The characteristics of the designed structure are investigated by using MoM based electromagnetic solver, IE3D. An extensive analysis of the return loss, radiation pattern, gain and efficiency of the proposed antenna is shown in this paper. The simple configuration and low profile nature of the proposed antenna leads to easy fabrication and make it suitable for the
