This study presents a unique frequency-reconfigurable antenna that may be the first to use a dip switch and a bias circuit integrated on the same substrate as the antenna. Such an antenna may be used for many wireless applications, since it is small and versatile enough to operate in several frequency bands with different modes. Printed on a Rogers RT5880 substrate, the suggested structure has a relative permittivity of 2.2, a tangent loss of 0.0009, and a size of 28 × 26.35 × 1.6 mm3. Three-PIN diode switches are inserted between radiating patches. The proposed antenna operates in four modes, covering nine different bands by using three dual bands (i.e., 4.36 and 7.78 GHz, 3.56 and 6.89 GHz, 3 and 6.2 GHz) in MODE 1, MODE 2, and MODE three, respectively, and triple band in MODE 4 (i.e., 2.88, 5.87, and 8.17 GHz). The efficiency of the planned antenna is 97.66%, and the gain varies from 1.38 to 4.89 dBi. The obtained bandwidths at corresponding frequencies range from 5.5 to 31.17%. The suggested structure is modeled in the CSTMWS and the simulated findings are experimentally confirmed. The suggested antenna may be employed in current portable (5G) devices and the IoT.

Modified H-shaped array antennas are proposed to achieve high gain and good impedance matching for WiMAXapplications. Here a 3*2 H-shaped microstrip array antenna is designed. To reduce the return loss and for good impedance matching, the 50 ohm impedance transformer is used. By using H-shaped slot antenna, an air bridge can be avoided in design as well as the complexity of design can be reduced .The 180 degree phase shifters are organised in H-shaped antenna. It gives 7.77 dB gain and 11.97 dB directivity. The return loss of 16 dB and 24 dB can be achieved at 3.3 GHz and 3.7 GHz operating frequencies which are WiMAX frequencies. Index Terms:Modified H-shaped antenna, WiMAX, 50 ohm impedance transformer, 180 deg phase shifter.

“…With some modification, adjustment of the PIN diodes switches positioned along the feed line, and different numbers of configurations, more frequency and pattern reconfigurability have been achieved. The details about the novelty or a new concept of coupling methods implemented in aperture-coupled technique to achieve the frequency reconfigurability have been explained in [16].…”

“…Basically, the design and structure of the proposed antenna have been published in [16], but it only focuses on frequency reconfigurability. Therefore, by applying the structure and concept from the single stacked patch microstrip antenna in [16], the 2 by 2 stacked patch microstrip array structure has been proposed in this paper. With some modification, adjustment of the PIN diodes switches positioned along the feed line, and different numbers of configurations, more frequency and pattern reconfigurability have been achieved.…”

Abstract-This paper presents a frequency and pattern reconfigurable stacked patch microstrip array antenna fed by aperture-coupled technique. The antenna consists of three substrate layers with radiating elements sorted at substrate layer 1 (top patches) and substrate layer 2 (bottom patches). The layers have different sizes to indicate different operating frequencies. On the ground plane, the four sets of two different aperture slot shapes (I-shaped and H-shaped) are used to transfer the wave and signal to particular radiating elements during the PIN diode switches configurations. The I-shaped slots are used to activate the bottom patches while the H-shaped slots are used to activate the top patches. Four PIN diode switches are placed at the feed line, positioned between the I-and H-shaped slots. Next, by changing the PIN diode switches configuration to ten cases, the proposed antenna has capabilities to change the operating frequencies and the pattern characteristics itself. The measured results of return loss, gain and radiation patterns have slightly shifted compared to the simulated results.
