A simple tri‐band monopole filtering antenna using multimode resonators is proposed. Two novel microstrip open‐loop multimode resonators and a monopole ring antenna with an open stub are integrated together on the same layer of the substrate. Compared with the traditional monopole antenna, the integration makes the proposed antenna operate at 2.4/5.2/6.5 GHz and realize two radiation zeroes at 2 and 3.3 GHz. It leads to the high selectivity for 2.4 GHz. The measured results, including the reflection coefficient, peak realized gain and radiation pattern agree well with the simulated results.

This paper presents a novel design of 4 GHz substrate integrated waveguide (SIW)radiating bandpass filter using multilayer technique on the Printed Circuit Board.The circular cavity structure using TM 010 mode for both filter and rectangular antenna areemployed in the design of this radiating bandpass filter. To realize the technique, modes of SIW filter and microstrip antenna are coupled using rectangular aperture at common ground plane.The simulation result shows good antenna gain and radiation pattern that prove the capability to integrate SIW filter and microstrip antenna directly without requirement of external matching, thus reduce the overall size of the device. To prove the concept, the multilayer structure is fabricated using Rogers RO3003 with dielectric constant, = 3. The measured results show good agreement with the simulated results.

“…The design of filtering antennas is currently accomplished by following one of two approaches. The first is to use a separate filtering structure that precedes the antenna [10]. This approach has the drawback of increasing both the insertion loss and the footprint of the whole circuit.…”

This paper proposes novel low-profile differential-fed planar antennas with embedded sharp frequency selectively. The antennas are compact and easy to integrate with differential devices without matching baluns. The antenna design is formulated as a topology optimization problem, where requirements on impedance bandwidth, directivity, and filtering are used as the design objectives. The optimized antennas operate over the frequency band 6.0–8.5 GHz. The antennas have reflection coefficients below −15 dB, cross-polarization levels below −42 dB, a maximum gain of 6.0 ± 0.5 dB, and a uniform directivity over more than 130° beamwidth angle in the frequency band of interest. In addition, the antennas exhibit sharp roll-off between the operational band and frequencies around the 5.8 GHz WiFi band and the 10 GHz X-band. One antenna has been fabricated with a good match between simulation and measurement results.
