“…The antennas with dual polarization characteristic have also been reported [11][12][13]. Moreover, the gain enhancement researches have also been reported [14][15][16][17][18][19]. Therefore, there are many reports for dual polarization or gain enhancement individually.…”

Abstract-In this paper, a linear polarization switchable planar array antenna with enhanced gain and better crosspolarization is proposed. The proposed array antenna consists of a fed patch and four parasitic patches. Four switching diodes are loaded on the corners of the fed patch. The boundary condition of the fed patch is controlled by using the ON/OFF condition of the diodes, and the polarization angle of the array antenna can be orthogonally switched to ±45 • with better than −22 dB of crosspolarization. The simulated gain of the array antenna is remarkably increased to 12 dBi by using four parasitic patches surrounding the fed patch. For matching the resonance frequency of the parasitic patches with the fed patch, a square slot is formed at the center of each parasitic patch. The characteristics of the proposed array antenna are investigated by the FDTD simulation method. The array antenna is fabricated and the experiment is carried out. Both the simulation and the experimental results of the proposed array antenna demonstrate the polarization switching functionality successfully with the enhanced gain in S-band.

“…However, most of the S-DMB antennas in published papers [4][5][6][7][8] only have receiving or transmitting function. Microstrip antennas [7,[9][10][11][12][13] usually have an important advantage of being low profile, low cost and easy fabrication. Biconical antenna [14][15][16][17] is connected with a SMA connector to excite a TEM mode, resulting in the uniform radiation pattern in the H-plane.…”

Abstract-A dual-band multifunction hybrid antenna for carborne satellite communication relay system is presented in this paper. As a consequence of the radiation requirements, the proposed antenna consists of a left-hand circularly polarized (LHCP) microstrip patch and an omnidirectional biconical antenna with a conductor tube holding and radome. The LHCP microstrip antenna is used for satellite signal reception, and biconical antenna is used for relay communication transmission. A novel overmoded coaxial waveguide feed structure eliminates the interference between two feed ports. The proposed antenna has the advantages of robustness, low cost, and easy fabrication with conventional materials and printed circuit technology. An antenna prototype is fabricated to validate the design. Both the simulated and measured results are obtained with reasonable agreement.

“…However, in these techniques no concrete mathematical reasoning is provided in the literature. Moreover, all these techniques suffer from the problem of poor radiation characteristics, complexity and enlarged element size as reported in [10].…”

“…Many other techniques include slot-loading [6], chip loading [7], stacked shorted patch [8], using parasitic patches [9]. A new design of the microstrip patch with reactive load leads to new configuration is proposed in [10]. Using negative capacitor with a chip resistor incorporated in rectangular microstrip antenna around 4.23% bandwidth [10, Table 3] is obtained.…”

A single layer single element rectangular microstrip antenna on ridge ground plane for improved bandwidth is theoretically investigated with a view to develop a concrete physical insight in to the phenomenon. The simple single element probe fed rectangular microstrip antenna fabricated on conventional PTFE (Poly Tetra Fluride Ethelene) substrate have many advantages except its narrow bandwidth. The present study proposes the technique to control the resonant modes of a microstrip antenna for yielding better bandwidth using transverse resonance method. The present antenna is designed to fabricate on ridge ground plane which has been compared with conventional structure and around 6% -7% improvement in bandwidth is revealed. The detailed variation of radiation pattern across its frequency band has been studied and presented in this paper. The proposed idea has been verified through a commercial software package (High Frequency Structure Simulator) for a patch operating in X band and explained quantitatively. The electric surface current distribution over the patch surface for both the conventional and proposed antenna is presented to explain the broad banding effect physically.
