“…The antenna was compact, but its bandwidths were narrow. In Reference , a rectangular aperture loaded with T‐stubs was excited by two T‐shape microstrip lines. This antenna exhibits self‐duplex behavior, but its channel selectivity needs to be improved.…”

A compact duplex filtering antenna using a T‐shape probe‐fed patch and hairpin resonators is proposed. First, the T‐shape probe‐fed patch is designed as a dual‐band radiation element by connecting a microstrip line to the patch. Then the dual‐band radiation element is coupled to two bandpass filters based on half‐wavelength hairpin resonators directly to construct the duplex filtering antenna. The two modes of the dual‐band radiation element function as last stage resonators, improving the selectivity of both the transmitting band and the receiving band, increasing the bandwidths, and enhancing the isolation. A prototype antenna is fabricated and measured. The measured results agree well with the simulated results.

This letter presents a slot‐based self‐diplexing MIMO (multiple‐input multiple‐output) antenna for dual‐band operation. In the first step, a self‐diplexing antenna is designed with two microstrip fed quarter wavelength slot‐antenna elements. Next, this self‐diplexing antenna is replicated to obtain the characteristics of a MIMO antenna. The designed self‐diplexing MIMO antenna with optimized dimensions operates at 5.1 GHz and 5.7 GHz. The peak gains obtained at two frequencies are 2.02 dBi and 2.96 dBi. Minimum isolation at both the operating bands is better than 15 dB. The proposed antenna offers a frequency ratio of 1‐1.62.

“…The antenna gains of radiation patterns were lower than 0 dBi with poor cross-polarization levels. A dual-band self-diplexing antenna equipped with double T-stubs loaded aperture was designed in [5]. The half-power beamwidths (HPBWs), which represent the angles required for covering devices in the same field of view (FOV), are not the same in the two bands, and the antenna gains are quite different in the two operating bands.…”

A novel filtering diplexing antenna for dual-band operation is presented. The antenna is composed of a slot-loaded patch and two resonators with a commonly used ground. Dog-bone-shaped slots are used on the ground for achieving broadside magnetic coupling and increasing the isolation between operating bands. The antenna design is based on a second-order Chebyshev bandpass filter synthesis. The proposed antenna exhibits high band-edge selectivity performance, low cross-polarization levels with half-power beamwidths greater than 86° for 2.4-and 5.2-GHz WLAN communication bands. The measured and simulated results are highly consistent.Index Terms-band-edge selectivity, Chebyshev bandpass filter, diplexer, filtering diplexing antenna.
