“…The increasing need for multiband radio front ends has led to research on frequency reconfigurable antennas [1][2][3][4]. Wide to narrow band reconfigurable antennas have received attention [5][6][7], as they offer multi-functionality and are potentially important for future cognitive radio systems which employs wideband sensing and reconfigurable narrowband communications.…”

Abstract-This paper presents a novel wideband to narrow band reconfigurable log periodic aperture coupled patch array. The wide to narrow band reconfiguration is realized by closing a selected group of slot apertures, to deactivate the corresponding group of patches. The patches are fed with a modulated meander line through aperture slots. A wideband mode from 7-10 GHz and three selected narrow band modes at 7.1, 8.2 and 9.4 GHz are demonstrated. Potentially, the number of sub bands can be increased or decreased as can the bandwidth of the sub bands by selecting a specific number of active elements. To verify and demonstrate the proposed design method, a prototype has been developed with ideal switches. Very good agreements between the measured and simulated results are presented.

“…The design of an efficient wide band small size antenna, for recent wireless applications, is a major challenge. Microstrip patch antennas have found extensive application in wireless communication system owing to their advantages such as low-profile, conformability, low-cost fabrication and ease of integration with feed-networks [1]. However, conventional microstrip patch antenna suffers from very narrow bandwidth, typically about 5% bandwidth with respect to the center frequency.…”

Abstract-A new high gain wideband L-probe fed inverted EE-H shaped slotted (LEE-H) microstrip patch antenna is presented in this paper. The design adopts contemporary techniques; L-probe feeding, inverted patch structure with air-filled dielectric, and EE-H shaped patch. The integration of these techniques leads to a new patch antenna with a low profile as well as useful operational features, as the broadband and high gain. The measured result showed satisfactory performance with achievable impedance bandwidth of 21.15% at 10 dB return loss (VSWR ≤ 2) and a maximum gain of 9.5 dBi. The antenna exhibits stable radiation pattern in the entire operating band.

“…Recently, many techniques have been developed to enhance the bandwidth. The most commonly used ones are adding slots to radiating element [4][5][6][7] and partial ground plane [8,9]. In addition, the microstrip antennas are known by their disability to operate at high power levels.…”

A new small high-gain wideband rectangular patch antenna is proposed in this paper. The antenna has a simple structure where the dimensions are about 11 mm by 7 mm by 1.58 mm leading to a good bandwidth. The antenna structure is optimized and simulated using electromagnetic commercial software, and the measured bandwidth defined by return loss <−10 dB is 1.97 GHz from 10.94 to 12.91 GHz for simulated results and 2.75 GHz covering from 10.8 to 13.55 GHz for measured results using vector network analyser. The gain is up to 4.91 dBi with a good radiation pattern. The comparison between simulation and measurement results permits to validate the structure of the proposed antenna. The low expenses of this profile and its simple configuration allow for an easy fabrication process, with usability in many applications such as radar, satellite and wireless communication.
